More Robots at Barley
Still a work in progress but the hardware and electronics are complete. All that remains is to finish the programming.
My intention is to have these robot arms re-enact some of the "Great Brilliancy Prize" Games of the chess masters.
A central master UNO stores the command list for the moves, and feeds these alternately to two slave UNOs which drive the servos.
I rebuilt the shoulders and elbows to fit dual contra-rotating servos. A problem I didn't anticipate was that the servo travel from 0 deg. to 180 deg. is not exactly linear. I had to build in a numeric adjustment of up to 5 deg. in the "write" commands, to keep the partner servos as close as possible in synchronisation. The master UNO can also issue a command to park and cut the power on the currently inactive arm, to minimise overheating of the servos in that arm.
