This is a RC car controller for a hypothetical driver whose arms only go up to his/her elbows and only has one leg. The special controllers were designed, manufactured, and tested within a three-week period and received a score of 8 out of 10 for ergonomic design and efficiency. We emulated the handicap user by only using one leg and nothing from the elbows down while using the controller. To test the efficiency and ergonomic design, we had to complete one lap around an infinity shape track in the fastest time possible. Our speed was fast up until the three-fourths mark when one faulty conductor prevented the RC car from completing the track. The issue was the conducting plate not always making connection with the wires due to its small size. It is an easy fix.
