I used an arduino to control the motor controller for now. I plan to upgrade to a Raspberry pi 4 to control the motors and also run the speech recognition program pocket sphinx from Carnegie Mellon University. I have the speech recognition working as in “robot go forward” on a raspberry pi 3 but it takes around 5 seconds after saying it to recognize that’s what I said. I hope the raspberry pi 4 is quicker. The motor controller circuit is called 298N. With arduino there is a new programming language to use but it’s pretty simple. With Raspberry pi 3 and 4 you can use python.
I bought the chassis from Amazon:
You can get it at a better price somewhere else now. When I bought it, it was $160. The chassis includes 4 motors, but not the motor controller.Edit or delete this

Will someone buy this for me?
