Today, I ordered two motor controllers from Daventech (http://www.robot-electronics.co.uk/acatalog/Motor_Controllers.html). The MD03 model. I already have two PID motor controllers with encoder input and all the rest, but they can only deliver 3amps and my motors can drain much more.
So the idea is to using these MD03 drivers that can cope with 20amps current. They can be controlled via I2C protocol which I planning to use to connect all the robot elements. These drivers can also use PWD + sense signal, so later, I am planning to re-use my PID controllers to get accurate position and speed. I will cover this later I guess.
So now, I just need to wait for the delivery and start testing...
