Robotic Chess Machine
I started building
"Robotic Chess"
by sanding and staining the wood base, which are approximately 16 x 16
inches. After the base, the sliders were mounted and the gantry
was constructed to be attached to the sliders. The motor belt and
pulley for the Y-axis was attached to the base, and the belt was
attached to the slider. The horizontal mechanism for the X-axis
was mounted to the gantry, and the vertical mechanism for the Z-axis
was attached to the horizontal mechanism. Then the gripper was
attached to the vertical mechanism. Finally, the wires for all
the motors were stripped, soldered, and crimped. The final piece
of the project, before the programming of the robot is the chessboard.
Through programming, the robot is
able to move the chess pieces on the chess board. This is done by
sending pulses ot the individual stepper motors. The robot is
wired to the computer using a bread board interface, located between
the robot and the computer. Two stepper motors on the robot can
be commanded to move forward, back, left, or right to move the chess
piece around the chess board. The third stepper motor moves the
chess piede off of the board and back down, allowing the chess pieces
to pass freely of each other. A gripper, which utilizes a
solenoid, grabs the chess pieces, so when the vertial motor is used,
the chess piece moves with it.
