Let's Make Robots!

Servos, steppers, and motors

Hello everyone,

I am starting a robot build using an arduino board. It will have 4 legs with knee joints that end in wheels. Each wheel will have forward/reverse movement and will turn both directions to steer. The result will be a wheeled robot that can dance.

Please provide advice on what type of motors or shields to use. I believe servos might work best for the knees. DC motors for the wheels and stepper motors for steering might help reduce costs. Any thoughts?

Also, are there any shields that work well with a good number of motors? The driving wheels could all be run by the same controller and the steering motors could be operated in pairs.

Thanks for the help,
