Using the Lynx6 and Rios, I am playing around with having the arm pick up a block, move around and then put the block back. I am finidng that in certain positions, the entire arm shakes violently. However, this seizure stops as soon as I move slightly.
Edit: The shoulder shakes worse at ~90 degrees, and the load bearing springs hindered motion more than helping.
My question is two fold, A) What causes that shaking? and B) How do I prevent it?
Is the arm new or well used? The pots in servos can wear causing eratic behavior when the pot wiper tries to sit on the wear spot. A spring adjustment might help eliminate the possibility of a resonate condition at that particular position.
It’s not really clear what’s going on by a description. Can you post video? Does it effect one axis more than others? There are some power issues that can effect this. Make sure the VS=VL jumper is removed and the SSC-32’s VL terminal is powered by a 9vdc battery. Let me know…
Check to see if the servo has become unplugged to the servo extender cable. How was the elbow servo found to be unresponsive? Was the robot in use at the time?
The servo is plugged in, and all the other servos are working properly. The elbow servo is not even resisting motion. When a different motor is plugged into that pin the other servo works, and when this servo is plugged into a different pin, it fails to work.
I can replace the servo for you. I will need the invoice or order number, and the old servo returned to me. Please contact me with a pm with this information.
