Bad Piggies: Tow Trucks

These tow trucks all share a similar design. The boom is based on an articulating set of springs and soda bottles that is counterweighted by a V8 engine and a pair of controlling propellers. An inverted rotor is set underneath the tow truck to serve as a brake and to stabilize the truck while the boom is in use. Each tow truck has a degree of specialization to accomplish a specific task. The first tow truck uses the end spring to latch onto a contrived umbrella bumper on the target vehicle. The connection is reversible, so the vehicle can be dropped off at a later time. The tow truck does not have a reverse drive; I use the momentum of the boom as it is lowered in order to back the tow truck into position. The second tow truck features a more realistic wheel-lift system that uses a spring to cradle the drive wheel for towing. The unrealistic part, of course, is that you need to drive the target vehicle onto the cradle. To facilitate this, I attach an air bellow on the end, which performs several nearly simultaneous functions when actuated: 1) The air bellow pushes the cradle toward the truck so it is lodged into a secure position with the air bellow angle down. This helps the target vehicle drive onto the air bellow. 2) The air bellow is thinner when actuated so that the target vehicle can more easily drive onto it. 3) The air bellow automatically re-inflates so that it lifts the vehicle up, which allows its wheel to easily drop into the cradle. A significant drawback to this design is that the connection cannot be readily reversed. The third tow truck is intended for heavier loads. It uses an umbrella and tiny wheel as a locking mechanism so that the boom doesn't swing back due to the load inertia. The boom has some trouble lifting the heavy load, so there is definitely some room for additional optimization of this design.
