I’ve been working on some finishing touches to the mechanical design of R2. That includes creating a battery rack to house to the two batteries. One battery provides power to the onboard computer (6 volts). They other battery provides power to the linear actuators that control the steering, accelerating, and braking systems (12 volts). It’s not exactly electrical engineering, it’s more mechanical engineering, but that’s why I like EE: it combines Computer Sciences and Mechanical Engineering, plus some other stuff into a nice little bundle of joy. Woo-hoo!
