Step 3Simply Fold in Half
We were lucky to have frames with an abundance of holes already drilled (which didn't make much sense to us, were these so you could hang ornaments?)
So we cut some small tabs with which to re-attach the motor so it would be oriented correctly relative to the drive pulleys on the tape players.
This part was tricky because if the wheelbase was too narrow it would be unstable and unmaneuverable, but too wide and the angle of the pulley would be too severe and pop off. So we married the players with anchor bolts and tightened them bit by bit until we got to a gap where all was working well.
Just a note: You can get these tiny belts online, but we used rubberbands because they were handy, free, and worked better on our robot than in a landfill.
