Fully constructed prototype. Only the steering mechanism needed to be tested, so things like seats and motors were left unrepresented.
Testing of the steering mechanism. The real EV would not be constructed to turn in this manner, but cutting these grooves allowed us to simulate a steering system quickly and simply.
Overall, this prototype demonstrated a capability to make turns, and while of limited applicability to the full sized EV, gave us the confidence we required to proceed with the design.
