Raspberry Turk

By Joseph Meyer |

The Raspberry Turk is a robot that can play chess—it's entirely open source, based on Raspberry Pi, and inspired by the 18th century chess playing machine, the Mechanical Turk.

The arm is primarily made out of Actobotics components. It is a Selective Compliance Articulated Robot Arm (SCARA) which means that it can move freely in the XY-axes remaining fixed in the Z-axis. The motion is controlled by the rotation of two servos which are attached to gears at the base of each link of the arm. At the end of the arm is another servo which moves a beam up and down. At the bottom of the beam is an electromagnet that can be dynamically activated to lift the chess pieces. The base of the arm is fixed to the table-top box.
