The treads were held together using the long pegs and attaching beams to the sides to keep the treads rigid.

This design did not work in a test because the robots were not level, making it so not all the wheels were on the ground, prohibiting it from driving correctly.

Knowing that only the brick needed to cross the gap, we could have built a much simpler robot of the brick attached to the treads, similar to above, but with the brick in the middle of the treads. The brick would drive until the treads spanned the gap, then would drive a motor that turned the treads to move the brick to the other side of the gap. When trying to build this originally, we were unable to find a way to get all of the tread onto the other side of the gap, and believing that was necessary, that robot idea was scrapped. After building the robot above and finding it did not work as intended, time was running out, but we also realized it was only the brick that had to cross the gap. With only a few minutes to go, we modified our robot to be just a car that would jump a gap using a ramp made of the cardboard insert from the kit, the lid to the kit, and the other EV3 brick.

We believed that our robot simply wasn't aligned properly when we had it start to move, so we readjusted its orientation and tested once more, right before time was up.

This final test left us with a broken robot as time expired, leaving only what follows for documentation of the competition itself.
