Hi,
It occurs to me that if you use a pair of rotation sensors to manually
control the structure the sensors that are embedded into the structure
aren't really necessary ... or are they? What if you simply included a
couple of clutches to protect the motors. Wouldn't it work just as well?
cheers

| (...) Hi, Think of it like a robot arm. You can't get the precise control without the onboard sensors. It operates almost like an extension of your fingers. Also you wouldn't be able to program autonomous routines. It also enables self centering on (...) (18 years ago, 9-Dec-06, to lugnet.robotics)
