Initial Experimental Setup

I will have a laptop computer running Ubuntu Server Linux. I want to connect it to a Motor Controller via USB (or Serial). I want the Motor controller to control two motors. The idea is that the motor will drive wheels connected to the laptop to drive it on a carpet. Steering is achieved by one motor going backwards while the other goes forwards. The motor needs to be powerful to do this.

Note: I will be writing a C++ program to send the serial commands to the Motor Controller.

Products that I think will do this

TReX Jr Dual Motor Controller DMC02 - This is a serial motor controller that can drive two motors. - £34.99
Motor - GM9 - Gear Motors 2 x £7.00 = £14.00
