I spent most of every Saturday during the school year in shop with the rest of the MIT Solar Electric Vehicle Team. Most of the car had been designed, but simulations had to be done, components machined, and fits checked.

My focus was on front suspension and steering. When you turn the steering wheel left, for example, the right (outside) tire is farther from the center of car rotation than the left (inside) tire. This means that the outside tire must rotate less than the inside tire in a turn if you want to avoid skidding.

In 1818, Rudolph Ackermann patented a design which corrects for skidding through the use of a trapezoidal linkage at the front wheels.

This design is used in cars today, and I helped the MIT Solar Car team deploy it on 2020 car build.
