I will show you how to make an Lego Mindstorms Car without using any batteries to make it move!

See? I wasnt joking:)

Step 1: You Will Need:

NXT Mindstorms 2.0 Kit:
2 Electric Mindstorms NXT Motor
2 Technic Axle 9
1 Technic Axle 5
4 Technic Bush 1/2 Smooth
1 Technic Bush
4 Wheel 43.2 x 22 without Pinholes, with External Ribs
4 Tyre 43.2 x 22 ZR
2 Technic Gear 36 Tooth Double Bevel
1 Electric Cable NXT 50cm

There's a cable sticking out of the motor, it's hooked to the nxt which is off camera.
<p>Actually, your wrong. It is NOT hooked onto the NXT, and the NXT is not off-camera either. In fact, I even tried this, and it turns out energy can be transferred between 2 motors. But he didn't really mention that the car can't steer. </p>
Oh wait i see what you did nevermibf
Good idea! I've done this many times with model motors. Why didn't I ever think to do it with Mindstorms? :)
Nice Instructable, I found that this technique makes for very good proportional steering on wire-control models.
