This is the result of the first chassis print! Having discovered an abundance of hoarded Raspberry Pi 0Ws knocking about, I am probably going to go ahead with using that platform for prototyping, I have also decided that I will go with active nose wheel steering rather than differential steering, the differential steering presented a challenge for me to implement, given that I am new to coding. I however have not given up on it and will come back to it in the future.
