Programmable robot car

Post by Cbuckley07 »

I currently have a whole bunch of Adafriut 3216 chassis and motor kits. I would like to make them into programmable robot cars that would be programmed to run a course. What should I get to run them a raspberry pi or I also saw a featherlight bluefruit? Thanks for your help and advice.

It depends on what you mean by "run a course".

If you mean by remote control, then one of the Bluefruit options would be a good way to go since you could control it from most mobile-phones.
If you mean autonomously via 'dead-reckoning', then any simple microcontroller board would work. (Though I hope you are not teaching students dead-reckoning as it is a bad way to approach robot navigation!)
If you mean autonomously using sensors (e.g. line following, distance/obstacle sensing etc.) we'd need to know a bit more about the course.

My goal is for them to learn programming not so much robot navigation. Yes, I want the students to program the robot to run through a set course. Are there any microcontroller boards in stock currently? I just realized many are out of stock. Thanks

For the Mini Round Robot Chassis (#3216), you will need both a processor and a motor driver.

This guide shows a robot built on this chassis with a Crickit (which has the motor drivers) and a MicroBit. https://learn.adafruit.com/microbit-crickit-robot
We are out of stock on the Microbits at this time. But we do have a Crickit board for the Circuit Playground Express. Both these and the Circuit Playground boards are in stock.

The distance sensor shown in the guide linked above is optional.

Another option would be the Motor FeatherWing - combined with any one of the Feather processor boards:

The Feather 328P is the most basic of the Feather boards: https://www.adafruit.com/product/3458
