AT traction engine EM 3D model

The AT traction engine is a traction engine (see wikipedia on 'Traction_engine'), inspired by the '1902 Ivel Agricultural Motors Ltd traction engine' and runs on 2 AC-electric engines. 2 motors are used (one for each track) to allow the vehicle to make turns (vehicle control). The vehicle is controlled with 2 levers. The AC-electric engines themselves are powered directly (on-demand) using a set of batteries placed in the middle of the vehicle. The intent of these batteries is to supply power until arriving at the agricultural field. Upon arriving there, the batteries are disconnected and picked up and placed on the ground (using the handlebars and detachable floor plate). The controls are also detached from the vehicle yet remain connected to the vehicle allowing the vehicle to be controlled remotely. For the powering of the AC motors, an AC-power cable from the electricity mains grid is plugged into the AC-printed circuit board. The cables from the levers are also plugged into the AC-board.

The camera (the green box at the front) is used by the driver (manual control); it is pointed towards the ground and serves to view whether the vehicle drives correctly in its track. The screen is placed relatively low, and the driver can also look over it (so on-sight, without using a camera), to see the vehicle's relative position in the field.

The camera not used by the autopilot, the autopilot only has 1 measurement tool, namely a tool to count the revolutions of one of the wheels (and hence the distance travelled). The autopilot is only an additional feature, and the vehicle first needs to be set in it's starting position manually.
