Robots - 4QD - Electric Motor Control


4QD controllers have been built into a wide variety of robots taking part in the Robot Wars and BattleBots series. The house robotsĀ  such as Major Damage and Sir Killalot use 2 x 4QD-300 controlled via a DMR-203 radio control interface to provide really heavy duty traction control. Weapons that only need single direction control are often powered by our Porter 10. Our new Pro-160 has a direct radio control input and can be used for steering or weapon motor drive.


A popular solution for drive motors is 2 x DNO-10 controllers linked by our DMR-203 radio control interface.
