In order to control the wrench for Performance Test 3, the robot needed an additional mechanism. Team members constructed a pronged mechanism made out of a double angle strip and popsicle sticks, which was controlled using a Futaba servo motor. The servo motor was taped to the front of the robot on top of the wooden chassis for the test. Initially, the popsicle sticks were attached to the double angle strip with screws, but the sticks did not stay in place, so electrical tape was found to be a better adhesive. The team also leveled the robot, which was previously angled following the removal of the back wheels, by adding four 6.5” x 1” x 0.25” pieces of wood underneath the chassis. Finally, a QR code stand was added using two 5.5” double angle strips and additional wood.
