Now my newly made 3 DOF Robot Arm can solves 'Tower of Hanoi' problem
The design was based on the 'uARM metal' project and I did some updates with available materials. Firmware is GRBL 1.1, which is used to control CNC machines.
Need some position calibration mechanism and coordinate mapping function from Cartesian to Cylindrical for stepper motors driven by CoreXY arrangement.
