Todo:

Today we improved our front for the fuel cube collector. Previously, we had just mounted wheels on two motors on the frame directly. However the problem was pulling in cubes diagonally. We have thought about an arm tensioned by rubber bands/medical tubing.

Calculating the distance between the wheels

Afterwards we built a prototype, that did not use the right dimensions yet.

It worked great and reliably when we tested it.

The next step was to mount it to the frame of the robot. We inserted a little extrusion between the extrusions holding the wheels. To this we attached the angle bracket.
