I am working on, with some friends, a small project. It is to take a toy radio-controlled car and put a rotating electronic rangefinder on it in order to have it drive itself around SIMPLE obstacles. We all have a slight background in electronics (not much) and lots of experience in computer programming. We are currently torn between using a Zilog Z80, with required peripherals, or a microcontroller. The car is about 8"x16", so size really isn't a problem. It runs from two BLDC motors. We have decided on using two rangefinders, two color sensors, various servo motors, and other data-gathering peripherals. The rangefinders will be building a simplistic map of the car's surroundings in order to navigate them. Do you recommend us to use a microcontroller, build a full system with the Z80, choose a different option, or do something else with our time?
