Sirius Reveal:
https://www.youtube.com/watch?v=zxG7JpejR4g
Can someone tell me the name of the device that the robot Sirius uses in this video to control their arm? Their arm device is rotated using a CIM motor. If I'm not mistaken, CIM motors do not stay in place as Sirius's arm does when lifted off the resting position. Are they using some sort of gear box that locks the arm in any position in the given rotation? Or does a CIM motor have some kind of idle when powered and connected to a motor controller?
Thank you for taking the time to read this post! Any help is greatly appreciated
