Robot App™ Description

Que-boid can drive on four faces thanks to the track design.
The design for the track supports is taken from the LEGO 8294 Excavator; I used four excavator track supports attached by beams to build the model structure. I am very pleased with how reusable the LEGO 8294 design is. Why re-invent the wheel when you can build on the work of giants?
The battery pack is mounted on a fold-out frame on the side of the rover. Two medium Power Function motors have plenty of torque to drive the rover - it is surprising lightweight and sturdy. The LEGO NXT controls the motors via the Mindsensors NRLink interface. For simplicity I do not have any cables attached in the pictures shown.
