Reddit user /u/Available-String-891 showcased a homemade 4-DOF 3D-printed educational robotic arm that recognizes the opponent's moves via camera and autonomously plays a game of Nine Men's Morris; they state the video was recorded during the arm's first successful game. The arm's J1-J3 joints use POM gears from Tarot 450 helicopter main gears paired with NEMA 14 stepper motors, J4 uses an RC servo, the gripper is made of flexible TPU, and the controller is a BTT SKR Pico 3D printer board with TMC2209 drivers, supporting sensorless homing. The author states the first version is 4-DOF with room for expansion, and that subsequent movements will be smoother and faster.
