The robot’s front is a standard two-wheel front which then changed to tank like wheels. After that, I changed out the structure of the front. But I ended up reverting back to the original with some minor edits like an attachment where I have my weapon. There were also a few edits to the wheel where I made it stick on to the axle well. Third, my motor has a neat spot to connect to the wiring that goes through the entire robot so it is not exposing wire.
