4.电池使用多久

充满电后传感器使用4~5小时。

 

5. 有什么机器视觉库可以用吗OpenCVOpenCV
推荐基于视觉的定位系统作绝对位置定位跟踪。有些库可以用,如跨平台视觉库OpenCV,经授权可以在商业与研究领域使用。

 

6. Mocap Studio支持原始数据输出吗
Mocap Studio目前不支持原始数据,但由于是开源可以自己添加这项功能。需要开源代码,直接联系我们。我们正在升级Studio,

使得可以支持多种类型数据输出。

 

7. 3-Space Sensor Suite软件一次能从多个传感器读取数据吗

3-Space Sensor Suite软件一次只能连接一个传感器,也只能从一个传感器读出数据。但是,可以同时打开多套Suite记录多个数据,利用系统的时间戳同步数据。另外,如果你有一些基本的编程经验,您可以编写一段脚本(script)程序同步传感器时间戳,并在同一时间收集来自所有传感器数据。我们有基于C和Python语言的基本案例放在网上:

http://www.yeitechnology.com/c-code-examples#multi_wireless_sensor_example

http://www.yeitechnology.com/python-code-examples#multi_wireless_sensor_example

 

8. 我打算写自己的程序了,要与3-Space传感器通信,我该如何开始

您可以了解下3-Space传感器协议,与所有传感器/适配器指令,各传感器型号用户使用手册。我们将几个Python和C语言的案列放在了网上:

http://www.yeitechnology.com/python-code-examples

http://www.yeitechnology.com/c-code-examples

我们也提供API接口可以发指令和从传感器收集数据。

 

9. 无线传感器对比蓝牙传感器

一般说,无线传感器比蓝牙通信更可靠。可靠性与传输距离取决于传感器中的蓝牙模块。根据我们的测试,蓝牙传感器距离(约10米)明显小于无线传感器(大约30米或更远)。 个人电脑容许同时连接7个蓝牙传感器(取决于电脑)。我们看到的最好结果是移动Android装置连接不多于2个蓝牙传感器。无线适配器可以同时连接多达15个无线传感器,多个无线适配器可以连接于同一台电脑。无线传感器通信也更加平滑和迅速。通常,我们只推荐蓝牙传感器用于需要通过Android操作系统装置发送数据的应用。

 

10. 可以用Linux操作系统吗

我们的传感器兼容Linux。如果您对在Linux环境下连接一个传感器有疑问,可以参考我们的Forum。

3-Space系列AHRS/IMU传感

1.General 总则

1.1 What parts (accelerometer, gyroscope, etc.) do you use in your sensors?

We replace the parts we use on our sensor boards as better components become available,

so we cannot guarantee a certain part will be used on a given board.

 

1.2 Can I use the 3-Space sensors for positional tracking?可用3-Space传感器作位置跟踪吗

Our 3-Space sensors are only capable of accurately tracking rotational movements. Translational

tracking (distance, position) would require double integration of the sensor's acceleration reading,

which inherently introduces a lot of error. Although we do offer pedestrian tracking as a form of

positional tracking with our 3-Space mocap suit, this will only work with humans as it relies on

walking motions, and one foot being on the ground at any given time.

If you had some other way of tracking the velocity or position at any given time, it would be possible

to use this data in conjunction with our sensor to determine the position by dead reckoning:

http://en.wikipedia.org/wiki/Dead_reckoning.

However, if you want just one device to track position,

you may want to try looking into a GPS or something similar.

我们3-Space传感器能够精确追踪方向。平移跟踪(距离、位置)要求同时融合传感器器加速度数据,

会有误差。虽然我们的MocapSuit体感服提供行人追踪工作模式,但只适合个人,因为数据获取依赖步行运动,

任何时候有一只脚踏在地面。

如果您有其它方式获得速度与位置,就可以结合我们的传感器航位推算测定位置。

航位推算维基百科:http://en.wikipedia.org/wiki/Dead_reckoning。

如果您希望设备跟踪位置,可以考虑GPS或其它卫星导航系统。

2. Compatibility兼容性

2.1 Are 3-Space sensors compatible with Linux?

Our sensors are compatible with Linux. Please refer to this post in our forum for more information

and a few examples: http://forum.yeitechnology.com/viewtopic.php?f=3&t=23&p=69.

3-Space传感器兼容Linux操作系统,参考论坛上几个案例信息:http://forum.yeitechnology.com/viewtopic.php?f=3&t=23&p=69.

 

2.2 Are 3-Space sensors compatible with Mac OS?

Our sensors are compatible with Mac OS, and the drivers required to detect and communicate

with our sensors should already be installed. Our calibration software is currently only compatible

with Windows, but we do have sample code available on our website that will work on Mac:

3-Space传感器兼容苹果Mac OS操作系统,但要安装与我们传感器通信的驱动程序。我们的校准软件只支持微软Windows,

但我们有案例源代码放在网站上、可以配合Mac。

 

2.3 Can I use the 3-Space mocap suit or PrioVR with MotionBuilder?

Currently there is no way to capture mocap data live through MotionBuilder. We will be releasing

a plugin for MotionBuilder that will allow this. Right now, you can record animation files in our

Mocap Studio software (in BVH format) and import them into MotionBuilder.

目前Mocap Suit或是Prio不能通过MotionBuilder实时捕作数据。我们有MotionBuilder插件,可以先用

Mocap Studio软件录制动漫文件(BVH格式),然后导入MotionBuilder。

 

2.4 Can I use the 3-Space mocap suit or PrioDK with Maya?

You can record motion capture files (in BVH format) with PrioVR using our Mocap Studio software: http://www.yeitechnology.com/yei-3-space-mocap-studio, then import the files into Maya or other similar programs. We will also be adding FBX as an export format option.

可以先用Prio在Mocap Studio软件录制动作文件(BVH格式),然后导入Maya或其它类似程序。我们也会加入FBX作为输出格式选项。

3. Wireless 3-Space Sensors 无线3-Space传感器

3.1 I want to use a sensor that doesn’t require me to have a wired connection. What are my options?

Our wireless model communicates with our wireless dongles, which can be plugged into a PC by

USB and is used to communicate and collect data from the sensor in real time. The range on the

dongle is about 100 feet. You can learn more about this sensor and dongle here:

http://www.yeitechnology.com/3-space-product-family-category/wireless.

We recommend our Bluetooth model for communicating with Android devices in real time. Our

Bluetooth sensors work within a range of about 30 feet, but this depends on the range of the

Android device or adapter you use. You can see more about this sensor here: http://www.yeitechnology.com/productdisplay/3-space-bluetooth.

Our data-logging model contains a 2gb micro SD card which can be used to record data to later

download and analyze: http://www.yeitechnology.com/productdisplay/3-space-data-logging.

The battery life on all of our sensors is about 5 hours, and they can be plugged in to charge via

USB. They are also all capable of data collection via a USB connection.

 

3.2 I cannot decide whether I should use the wireless or Bluetooth model. What do you recommend?

In general, our wireless sensors offer better performance than our Bluetooth model, due to the

lower reliability of Bluetooth communication in general. The reliability and range will depend on

the Bluetooth module in your particular device, but our tests show Bluetooth range (about 10m

in our tests) is significantly less than the wireless range (about 30m). PCs will allow for up to 7

Bluetooth sensors to be connected at the same time (depending on the PC). We have seen the

best results with mobile Android devices using no more than 2 Bluetooth sensors. On the other

hand, each of our wireless dongles can communicate with up to 15 wireless sensors at a time,

and multiple dongles can be used on a single PC. Communication with wireless sensors is also s

moother and faster than Bluetooth sensors. Typically, we only recommend using Bluetooth

specifically for applications that require data to be sent to an Android device.

 

3.3 What is the battery life of the wireless, data-logging, and Bluetooth sensor models?

The battery life is typically 4-5 hours.  It is possible to extend the battery life with a USB battery

extender like you would use with a cell phone. For example, an 8400 mAh cell phone battery

extender would extend the battery life to about 3 days.

The battery is rated to last for 400 charge cycles until the battery life reaches 80% of its initial

capacity. We estimate the batteries should last around 18 months to 4 years depending on how

often they are used.

 

3.4 What is the range on the 3-Space Bluetooth sensor?

We have tested our Bluetooth sensors up to 15m, but found that they started working sporadically

after about 10m. However, the range you get will depend heavily on which Bluetooth adapter you

are using. The one we used for testing was a Belkin adapter (model F8T017).

 

4. YEI 3-Space Sensor Software/Firmware  3-Space传感器软件/固件

4.2 Can't Update Firmware

When I try to update my firmware, I am getting the following message: "This

firmware is not the correct version of this type of sensor." What am I doing wrong?

First, make sure that you have downloaded the correct firmware for your sensor model.

Second, make sure you are using the latest version of the 3-Space Sensor Suite. You can

download and install the latest version from this link:

  

4.3 Mocap Studio Data Options

 Can I export raw data (such as acceleration) from the Mocap Studio?

The Mocap Studio is currently not able to export raw data, but it is open-source so it is possible

to add this functionality yourself. If you would like to have access to the source code, please

email us. We will be updating the Studio to allow for more types of data output.

 

4.4 Logging with Multiple Sensors in Suite

Can I use the 3-Space Sensor Suite to log data from multiple sensors at the same time?
As the 3-Space Sensor Suite software can only connect to one sensor at a time, it can also only log data from one sensor data time. However,it is possible to open multiple instances of the Suite and record multiple logs simultaneously,using the system timestamp to synchronize the data. Alternatively, if you have some basic programming experience, you can write a script that synchronizes the sensor timestamps and collects data from all sensors at the same time. We have a basic example of this on our website in both C and Python:http://www.yeitechnology.com/c-code-examples#multi_wireless_sensor_example 
http://www.yeitechnology.com/python-code-examples#multi_wireless_sensor_example 
Depending on your application, you may be interested in using our Mocap Studio software to capture data from multiple sensors: http://www.yeitechnology.com/yei-3-space-mocap-studio. 
 

4.5 Writing Software for 3-Space

How do I get started writing my own software to communicate with the 3-Space sensors?

You can learn more about the 3-Space sensor protocol, as well as all of the available sensor/dongle

commands, in the user’s manual for your respective sensor model. We provide some examples on

our website of our serial protocol in Python and

C:http://www.yeitechnology.com/python-code-examples

http://www.yeitechnology.com/c-code-examples

We also offer an API which can be used to send commands to and gather data from our sensors: http://www.yeitechnology.com/yei-3-space-application-programming-interface.

 

5. 3-Space Sensor Settings & Options  3-Space传感器设定与选项

5.1 Acceleration Data

I see that 4 different types of acceleration data can be given by the sensor. What do these mean?

The raw acceleration is taken directly from the accelerometer and converted into units of g.

Corrected acceleration is the value of the acceleration once the calibration has been applied.

Normalized acceleration is the unit vector of acceleration, and gives only the direction of

acceleration (not the magnitude). The corrected linear acceleration in global space takes into

account the sensor's orientation, and gives the acceleration acting on the sensor in the global

frame rather than the sensor's reference frame. This value is also given in units of g.

 

5.2 Sensor Drifts after Disabling Magnetometer

I disabled the magnetometer on my 3-Space sensor, and now I am seeing a lot of

drift in my orientation data. Why is this happening, and what can I do about it?

All gyroscopes inherently have some drift over time. Unfortunately, it is not possible to compensate

for this drift without another external reference. In our sensors, we use the magnetometer data to

correct for this -- so if the magnetometer is disabled, you may be seeing some drift in orientation

due to this. You may want to try calibrating the gyroscope to decrease the amount of drift as much

as possible, but we recommend enabling the magnetometer and using gradient descent calibration

to compensate for magnetic interference.

 

5.3 Gyroscope Drift Rating

How much drift can I expect to see from the gyroscope if I have the magnetometer disabled?

The raw drift on the gyroscope is rated by the manufacturer as 11º/hour, but we have seen it drift

at about .92º/minute (55.2º/hour). Some of our sensors have been upgraded to have an improved

gyroscope, which is rated for a drift of 1.5º/hour. Upgraded sensors currently include the wireless,

embedded, Bluetooth, and data-logging models.

 

5.4 Gradient Descent 梯度下降

What is gradient descent?

Gradient descent is a replacement for ortho-calibration, and uses the same calibration process. Gradient descent
is designedto give more accurate results than sphere and ortho-calibration combined.
 
5.5 Filter Mode Options 滤波模式选项

I see that there are 4 filter modes available -- Kalman, Q-GRAD, Q-COMP, and IMU.

What is the difference between these, and which one should I be using?

The Kalman filter (which is currently the default filter) allows for rates of up to 250Hz, for both

logging and real-time data acquisition. This is currently the filter that we recommend for everyday

orientation data collection.

The Q-GRAD filter updates faster (up to 850Hz) and is more resistant to changes in magnetic field

than the Kalman filter, but since it is slower at incorporating changes in the accelerometer and

magnetometer readings it may take time to settle into the right orientation.

The Q-COMP filter updates at a rate of 850Hz or more over a USB connection with similar

performance and accuracy to the Kalman filter. This is currently the filter we recommend for

high-speed orientation data collection.

IMU mode does not do any orientation filtering (thus it allows for the highest data transfer rate

of up to 1300Hz), and should only be used for getting data straight from the accelerometer,

magnetometer, and/or gyroscope.

5.6 Strange Data with Euler AnglesI am using the Euler angle output, but in certain orientations my yaw and roll
values begin to look strange. Why is this happening?
If the pitch value nears 90º, this may result in inaccurate readings for the yaw and roll angles. This is due to gimbal lock,
which is an inherent limitation with Euler angles.
You can read moreabout this here: http://en.wikipedia.org/wiki/Gimbal_lock.
 
6.PrioDK
6.1 PrioDK vs. 3-Space Mocap SuitPrioDKPrioDK
What is the difference between PrioDK and the 3-Space Mocap suit?    PrioDK与Mocap suit的不同之处
The functionality of PrioDK will be essentially the same as the 3-Space Mocap suit.The main difference is that PrioDK has all of the sensors daisy-chained to one another and uses 1 hub for wireless communication. On the other hand, the 3-Space suit's sensors each have their own wireless module which not only increases the overall cost of the suit, but also means that communication is slower, and there is a greater chance of wireless interference when using multiple suits. However, this also means that the 3-Space suit offers more freedom of movement, as well as the ability to use the sensors individually.PrioDK is targeted toward gamers and for game content creation, so the suit design makes it simple and fast to put on and is pre-configured for the human body. The 3-Space mocap suit is more customizable, with options that can be set on how to capture data,filter parameters, etc. The accuracy between the two suits is about the same.
PrioDK体感服与Mocap suit动捕服基本功能是一样的。不同之处在于PrioDK所有传感器都是彼此菊花链接,提供一个集线器与主机做无线通信;3-Space suit每个传感器有自己的无线模块,成本有所增加、通信变慢,还有可能在同时使用多套动捕服时产生无线通信干扰;当然动捕服给了你更大的自由度,同时每个传感器可以单独使用;PrioDK针对的目标市场是游戏玩家和游戏内容制作者,所以设计为简单和快速穿上,已经预设置好了适合全身身体;动捕服则更加个性化,有如何捕作数据的设置选项、滤波器参数等;二者精度基本一样。
 
6.2 Motion Capture Gloves
Will PrioDK include motion capture gloves? 

Motion capture gloves which will integrate with PrioDK directly are being considered.

However, development on this would not begin until after the first release of PrioDK in 2016.

 

6.3 Using Multiple PrioDK Suits 多套Prio体感服PrioDK多人玩的躲避球游戏,同一空间多达30个人各自穿PrioDK一起玩!PrioDK多人玩的躲避球游戏,同一空间多达30个人各自穿PrioDK一起玩!

How many PrioDK suits can be used in the same physical space?

Each suit will require its own base station for communication, with approximately 30

PrioDK suits being supported in a shared space. 同一空间,多达30套Prio体感服,每套体感服需要一个盒子(基站)。

 

6.4 PrioVR Lite vs. Core vs. Pro 目前统一为PrioDK

What is the difference between the PrioVR Lite, Core, and Pro suits? 

The difference between thesof 11 sensors plus the chest hub sensor. Sensors are

located on the hands, lower arms, upper arms, chest, head, upper legs, and lower

legs PrioVR Pro is the full suit which includes 16 sensors plus the chest hub sensor.

Sensors are located on the hands, lower arms, upper arms, chest, head, upper legs,

lower legs, shoulders, feet, and torso.

 

6.5 Game Compatibility

What games will PrioDK be compatible with?  PrioDK兼容的游戏

3 demo games will be released with PrioDK. One is a zombie survival game (we have

been showing off this game at several conferences), another is a dancing rhythm game,

and the third is a dodgeball game. Third party game developer support and an emulation

layer for older games will be available.e suits is the number of sensors. More sensors allow

you to track more body parts more accurately. Each suit has the following number of sensors:

Prio Lite is upper body only with 7 sensors plus the chest hub (which includes a sensor).

Sensors are located on the hands, lower arms, upper arms, chest, and head.

Prio Core is the base suit.  目前PrioDK随机带僵尸生存游戏、跳舞游戏、躲避球游戏供三款。

鼠标仿真

替代电脑鼠标,作为空鼠标工作;也可解除鼠标仿真工作模式。
以TSS-BT蓝牙惯性传感器仿真鼠标为例:
首先TSS-BT与电脑设备配对,然后Sensor Suite, Sensor菜单 -> Sensor Info,跳出HID仿真窗口,勾选Mouse格,确认OK.
电脑鼠标不能工作,空鼠标(鼠标仿真)可以控制光标。
取消空鼠标,Suite -> Sensor Info,Mouse格勾选取消,就可以用回电脑鼠标了。
To use a Bluetooth sensor as a mouse, fellow these instructions:
• Pair the Bluetooth device with your Computer. To do so, please follow the Bluetooth Sensor Setup instructions at: http://www.yeitechnology.com/sites/default/files/YEI_TSS_Quick_Start_Manual_3.0_r1_4Nov2014.pdf
• Connect to the sensor in the 3-Space Sensor Suite
• In the Sensor Suite, under the Sensor menu -> Sensor Info. A popup with a HID Emulation box will appear. Check the Mouse button, and press OK. Your mouse will now be disabled and the sensor will now control your cursor.
• To undo this, navigate back through the Suite -> Sensor Info and uncheck the Mouse box using the sensor.

ServoCenter Questions伺服控制问答

1. Industrial robot,such as Fanuc,Kuka,Nachi,Kawasaki,ABB, Staubli,Comau,Epson,Yaskawa,Siasun (China manufacturer) are top 10, it seems its field are different from ServoCenter, correct? Explain the position of ServoCenter please.

十大工业机器人,包括Fanuc,Kuka,Nachi,Kawasaki,ABB, Staubli,Comau,Epson,Yaskawa和中国的新松,ServoCenter似乎与工业机器人领域不同,请解释。

>Unlike industrial servos which are designed to control massive industrial robots, RC servos are small, cheap, mass-produced actuators used for radio control and small-scale robotics. Today, RC servos are used in small-scale robotic applications, animatronics, unmanned aerial vehicle (UAV), including hobbyist and professional applications.

The ServoCenter™ family of embedded servo controllers allows RC servo motor control from any USB, serial RS-232, MIDI-capable device. ServoCenter is also available in DIP and TQFP chip packages. The ServoCenter 4.1 Sequencer allows complex tasks to be programmed via a script sequencer in addition to other programming options that are standard in the ServoCenter products.

ServoCenter allows amazing and unsurpassed control of the seek position and seek speed of up to sixteen connected servos -- independently and simultaneously, with simple, logical commands. ServoCenter also offers 16 channels of digital I/O which allow it to act as an easy interface for a variety of development needs.

不象工业伺服马达其目的是为了控制大量的工业机器人,RC无线电控制伺服马达是小、价格便宜、大量生产的执行器,用于控制各种小型机器人。今天,RC伺服用于小型机器人应用,电子动画,无人驾驶飞行器(UAV),包括业余爱好者和专业应用。

该ServoCenter™系列嵌入式控制器伺服允许RC伺服电机控制任何USB、串行RS-232、MIDI功能的设备。ServoCenter也可以是DIP和TQFP芯片封装。该ServoCenter4.1序程序除了那些属于ServoCenter产品标准的编程选项,复杂的任务还可以通过脚本序进行编程。ServoCenter允许惊人的、无与伦比的控制,连接高达16个位置和速度伺服马达 - 独立、同时运转,用简单的逻辑命令即可。 ServoCenter还提供16通道的数字I/O接口,允许它作为一个简单的界面,适用于各种开发需求。支持伺服马达电位器、角度传感器反馈数据输入I/O数字接口。参考应用案例(http://www.aitcl.com/products/servocenter/) 

2. SeroCenter is embedded controller of RC servo, ServoCenter connects servo and host remote controls ServoCenter, correct? If yes, ServoCenter has Rx & Tx parts, correct?

>You are correct, each ServoCenter board can control up to 16 servos. The ServoCenter is controlled via host. The host controls the ServoCenter via direct USB or serial RS-232, or MIDI connection. The ServoCenter MIDI can be controlled by almost any MIDI-capable device including digital audio workstation, MIDI keyboard controller, sequencer, etc. The ServoCenter 4.1 models are controlled via on-board sequencer, computer, microcontroller, or other electronic device capable of using our intuitive control protocol.

每块ServoCenter板能控制多达16个伺服马达。ServoCenter由上位机控制,有RS-232串口或USB、MIDI接口。ServoCenter MIDI 能控制几乎所有MIDI设备,包括数字音频工作站、MIDI键盘控制器、定序发生器等。ServoCenter 4.1型控制器能由板上序发生器、电脑、微控制器或其它采用我们直观的控制协议的电子设备控制。ServoCenter控制16个Servo马达ServoCenter控制16个Servo马达

 

 

 

 

 

 

 

 

 

 

 

 

 

3. Could we say Industrial Robot is mainly for heavy industrial, ServoCenter is for light industrial? Please list some examples and possible applications. We need more instructions to target market.

>ServoCenter can control almost any RC style servo. RC Servos are available for almost any application ranging from miniature motors designed to fit on a UAV or small robot to larger high-powered motors designed for high-torque applications. To get an idea of possible applications, please visit our customer project showcase at http://www.yeitechnology.com/servocenter-project-showcase

ServoCenter能控制几乎任何遥控型伺服电机,不管是小型马达设计无人机或机器人,还是大力矩应用的大功率马达。

4. Does ServoCenter product family has Development Kit & board?

>I think the ServoCenter 4.1 can function as an all-in-one development kit to create products which can be implemented as either a board-level solution of as a TQFP IC solution in a commercial product.

ServoCenter 4.1也适合做开发板,创立执行板卡级方案和TQFP芯片级商业产品方案。

5. When will you continue the update job?

>ServoCenter is a stable product and currently isn’t scheduled for updates or new versions.性能稳定成熟产品.

6. How about service robot and smart robot, could you give some solution proposal (TSS-EM + ServoCenter)?

>The TSS-EM could be used along with the ServoCenter to greatly simplify the creation of either dynamic/balancing robots or motion-controlled robots that mimic a user’s natural hand or body movements. For example, the TSS-EM could be placed within a robotic system and provide the sense of balance that the robot uses and processes to subsequently drive servos that are connected to a ServoCenter board. Another example would be utilizing TSS-EM modules mounted on a human body or in a hand-controller to sense movement information that would be sent to a robotic arm that is controlled by the ServoCenter. The resulting robotic system would allow tele-operation and could be placed in environments which are either dangerous or otherwise unsuitable for human workers.

TSS-EM、ServoCenter可用于服务机器人、智能机器人等,方便地创立动态/平衡机器人和动作控制机器人,模仿操作者的手臂、身体动作。TSS-EM传感器可置于机器人系统中感知平衡,机器人随后驱动连接到ServoCenter板的伺服马达。这样,遥控机器人系统可以在危险的场合或其它不适合人类工作的环境作业。

7. DIP chip and TQFP chip are basic controller, other boards with USB,series,MIDI,USB-mini port all base above mentioned chip?

>The DIP and TQFP chips are chip-only versions of the ServoCenter 3.1 line of servo controllers. These models are chip-only and are intended for customers who would like to integrate the chips into their own designs or products.

The USB and USB-MINI models are the latest line of ServoCenter 4.1 servo controllers. These servo controllers feature better performance and have more features than the ServoCenter 3.1.

The ServoCenter MIDI features a MIDI IN and MIDI OUT connector to allow servos to be controlled via MIDI controller such as a MIDI keyboard or digital audio workstation.

DIP、TQFP是芯片级ServoCenter控制器,适合客户打算集成控制器芯片到自己的产品设计中。

8. According to ServoCenter Project Showcase, it seems all are small power servo application, is it possible to apply ServoCenter to following mainstream fields: NC machine, Industrial robot, Injection molding machine (plastic)?

The ServoCenter can be used in any field that can utilize RC servos.

ServoCenter适合任何遥控马达应用场合。

9. ServoCenter is for DC servo motor only, not for AC servo motor, correct? If not, then not for Variable-frequency Drive field, correct?

The ServoCenter line of products is designed to directly control RC (radio control) servos. Radio control servos are connected through a standard three-wire connection: two wires for a DC power supply and one for control, carrying a

PWM (pulse-width modulation) signal. This signal is generated by ServoCenter controller.

ServoCenter产品线专为控制RC遥控马达设计,遥控马达通过标准的三线连接——2条线直流电、1条线控制线——执行PWM脉冲宽度调制信号。该信号由ServoCenter产生。

10.遥控伺服马达RC Servo、ServoCenter是无线控制的吗?

RC Servo是一种闭环系统(直流电机DC、步进电机是一种“开环”系统),指通常用无线电遥控(Radio Control)电路进行操作的的伺服电机,伺服电机本身并不是无线电控制的,只是连接到遥控汽车、飞机上的无线接收机,伺服电机从无线接收机取得信号,意味着不必通过无线电信号去控制机器人、遥控车等,应用于伺服电机即可。可以借助PC、微控制器控制伺服电机。

ServoCenter即伺服电机控制器。电脑上发指令,给ServoCenter即可,通过ServoCenter控制伺服马达。

脉冲宽度调制(英语:Pulse Width Modulation,缩写:PWM),简称脉宽调制,是将模拟信号转换为脉波的一种技术,一般转换后脉波的周期固定,但脉波的占空比会依模拟信号的大小而改变。
