rope climber - I designed and built the rope climber to race 3 stories up a 1/4" steel cable tensioned to the floor. Using 2 motors, each with one pinion gear and one large gear, driving the wheels. Using springs to tension the wheels to the cable. I also used four 9 volts batteries in a mix between series and parallel set up for maximum power. The design also had to be balanced and couldn't tilt while it was climbing. I received 2nd place.
custom car - Objective was to design a custom car based on the following constraints. The constraints of this car are that the car can only have 3 wheels, one in the front and two in the back. The front of the vehicle is supposed to lean into turns like a motorcycle while the back of the car stays stagnant and does not lean. The constraint is that the driving motor is supposed to sit on the front of the frame while it leans like a motorcycle, but it is supposed to drive the rear axel which does not lean. We therefore designed and built a foam prototype for a spherical gear and drivetrain housing.
unmaned picture frame assembly line - The object of this is to make two different size picture frames from start to complete product. Using timing belts to cut certain sizes of molded wood at 45 degree angles, metals rollers to carry the wood down to the rotating table where 4 pieces of wood get hydraulicly pushed together passing by the glue rollers and getting tacked around a piece of glass being hydraulicly pushed up from a lower assembly line. The complete frame is then lowered and moved into packing crates.
