Re: monkey rail

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
