Young humanoid, while browsing NXTLog, came upon ski4Jesus' project
pneumatic car. Eventually, young humanoid wanted to build one. Young humanoid used two cylinders to power the rear wheels. One NXT motor operated the dual switches using a mechanism copied off ski4Jesus' project. The second motor pumped air, while the third steered the front wheels. Although a fun experiment, the car exhibited both low speed and low torque.
