Gripper assembly and positioning?
Posted: Thu Feb 01, 2018 2:57 pm
Just a quick note re gripper assembly, correct me if I'm wrong:
If you follow the instructions, you will go through the servo centering process for pan, grip and tilt. When you then assemble the gripper, you are instructed to assemble it in a near-closed position (grippers pointing forward).
However, I notice that when doing the demo behaviors, this means the grippers are too far forwards.
I made my own Arduino sketch to put the gripper in stowed position, and then just removed and repositioned the arms. This seems to be working fine. You can use servo trim to adjust the arms to close exactly.
