New, better controller. Better motors. Improved mechanics.

Similar projects worth following
I managed to get an old robot arm. I wasnt happy with the controller so Im building my own! Along the way Im trying out different motors and ways to drive them.

The robot is made of aluminium and uses harmonic drives for all axes so its pretty solid. Originally the motors are brushed dc (which are simple to control), sadly axis 2 and 3 lack power and need to have more oomph. Id like to use cheap, lightweight bldc outrunners, with that come more challenges.

  • Encoder mounted

    Not the stiffest encoder mount but it should do the job in the prototype... The encoder is a HEDS 5500 K11 with 96cpr and was mounted at the backside of original motor

  • Pulley. Finally.

    The new pulley arrived today, now the bldc is ready to drive the axis! I still need to find a way to mount an encoder though...

Is this a Scorbot? At my lab we actually built an Arduino based controller to replace the stock one.
