Cool Frame Ideas?

We threaded the cubes and connected the sides with counter sunk bolts. this allowed us to quickly remove one entire drive module and replace it with a spare. Allowing us to make repairs without having to miss matches of work directly around the robot.

I am going to attach a picture of the chassis, if you have any questions feel free to ask.

Just curious.... Why were the center wheels located more towards the centerline of the robot than the outer wheels?

If I Recall it was just an ease of mounting decision. We wanted wide wheels in the center to push but didn't want to have to make the whole drive module wider.
