Hardware

1. The first part of the arm is the grabber, composed of 2 REV Robotics extrusions connected to gears spun by a Rev SRS servo.

2. The wrist uses a core hex motor, replacing the broken GoBilda torque servo. The wrist is used for bending the grabber back to fit inside the 18 x 18 x 18 square. It is also helpful when placing a pixel on the backboard.

3. The linear actuator uses a giant screw or lead screw, spun by a motor to go up and down.

4. We also have a motor to pivot the arm to pick up and drop pixels. The other side has another dead axle on a ball bearing on a c channel supporting the motor.

5. The airplane launcher uses rubber bands to launch the paper airplane. The servo holds the rubber band back then when a button on the controller is pressed, the servo will release.

6. We used a mecanum drive train with a rev chassis, and Rev Robotics ultra planetary motors with 20:1 ratio spinning Gobilda mecanum wheels. We have a wooden frame around the robot to protect the wheels and motors from accidents. Our Control hub and expansion hum are under the white sheet under the linear actuator.
