(...) The key to making this work is to ensure that there is tension at either end of the run that keeps the worm gear at one end of the axle or the other until it hits a hard stop. For example, my robot arm uses rubber bands to hold the gripper (...) (22 years ago, 13-Nov-03, to lugnet.technic, lugnet.robotics)

One of the most import parts of a moco system is how much space the camera needs to cover. They can range from just pan and tilt, commonly called a "hothead" which will either record or playback only rotational data (HPB), all the way up to systems (...)
