This is the first Robug a small electronic model which runs on the 2 1.5v cells with two motors and 2 gearboxes.

It self shape with no base as the gearboxes are join together as well as being attached by the battery pack.

the third wheel (the back wheel) is a tag along for balance and for support (as it has no base) it is attached to the battery pack.

at first this Robug went round circles as the motor were different voltages so when the power was low circles were all it would do.

now the motors are the same voltage and the gear boxes are attached by the axis's so it no choose but to go in a strait line.
