  • T-motor company was kind enough to send me two robot actuators with MIT mini Cheetah controllers. And It was a pleasure to test them. Thanks to the fast controller you can do the collision detection and bilateral telepresence.

    You could try using the STM32 you used for your DIY Mini Cheetah Controller as the brain. Most of the STM32 boards are programmable in the Arduino language and some even support CAN built in or have support for normal Arduino shields. And of course they are much faster than an Arduino.

      If you really wanted to make an awesome 3D printer, you might pick low/minuscule backlash, mid-range speed, high stiffness, and a controller that focuses on precision and not torque or speed.

      Yes. You can put torque = 0, this will be position control. If you also set stiffness to zero, this will be speed control. But for speed control there is a drawback: it has a limit at how many turns it can make. It cannot rotate indefinitely like with ESC.

      karry venkatesh yes, in my opinion this actuator should work, but your entire arm should be light of course!!! To control you can use arduino with can bus shield or teensy with can bus shield or stm32 or many others. Arduino would be the most simple. Teensy could be a good compromise, relatively simple and quite powerful.

      Simple question, but just to be sure: do you connect. Your connection should be like this:
      Ground - Ground
      Tx - RX
      Rx - Tx.
      Transmitter to Receiver, Receiver to Transmitter. Please check this. According to 2:12

      In this case maybe try another usb-serial converter. I don’t know. It should work.
      I had a problem when I was connecting it first time. Because I was using wrong cable (ground was in the place of receiver. And receiver was on the ground place), But on video it is shown correctly.

    When chaining the motors together, is there a trick to the CAN Id and Master Id settings on the motors? I can talk to a single motor fine but when I add another motor in (including the termination 120ohm) I can't talk to any of the motors?

    • @Skyentific
      @Skyentific  3 ปีที่แล้ว

      You need to change id. By default they all have id=1. Master id is usually equal to zero.

      Chaining 3 motors works fine as long as I don’t use id higher than 3. For some reason the id 4 and higher (i tried 4, 5, 6 and 7) does not work for me.

      365rpm, I don’t know where you need to have such high rpm. I don’t pay attention at rpm of QDD actuators, because they usually have enough rpm for most of the tasks.

      My opinion: Gyems has better mechanics (looks more solid, less backlash), but T-motor has better electronics (easier to control, more possibilities). I even think about taking Gyems actuator, and putting the better electronics (controller inside).

    I know these are quality actuators but the price is way out of the range of most hobby projects. Unless you are building some high priced professional product you will be looking at a much more affordable option such as the brushless gimbal motors on Aliexpress.
