2 cars, with the bigger one able to climb up the ramp and push the arm which sits in the base. The smaller car is meant to focus on pushing the balls on the table.
The bigger car was made with an aluminum base plate and acrylic claws which could aid in the pushing of balls sitting on the edge of the table. It also had strong magnets on its back, bonded by epoxy to the base plate. The car would ride up the ramp backwards and push against the arm. The magnets coincide with a plate of nails fixed to the back of the arm. The car will then be able to pull the arm back away from the center lever over the balls before pushing it back towards the lodged wedge to score. The smaller car has an acrylic base plate, and a ball caster for added manoeuvrability.
The arm: which also has a wedge release mechanism that deploys the hollow wedge into the slot after the center lever has been pushed away. We lasercutted acrylic for the arm. It is held by press fit rods, and it also has a main axle (that allows it to sit in the base) press fitted.
The base: in which the arm sits and slides. It was made out of lasercut plywood. It has two similar side plates, a top plate and a ramp, held together by brackets and hinges.
