RAD 2.0 Schematic?

Does anyone have a schematic or diagram outlining the electrical components for a RAD 2.0? 

Quick question on undrstanding a diagram

Hi friends,

I am making my first circuit from a diagram. I have made it all, but cannot figure out how to wire up the potmeter shown in red.

It has 3 wires, where do they each hook up to?

Thanks!

NEED HELP! with my motor controller


Hello guys. I'm creating a RF controlled 2.5kg sumo bot. I'm a mechanical engg. student and so don't have much knowledge in electronics.

Basically I need to create a 10Amp motor driver for driving 2 12V dc motors,10A each using relays.
Buttons on remote control:

      1
2           3
      4

1-Move Forward
2-Rotate Anticlockwise
3-Rotate Clockwise
4-Reverse


I'm planning to use these schematics for radio controlling
