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.


The 2016 / 17 series has seen a surge in interest and a number of competitors have chosen our controllers. A popular solution for drive motors is 2 x DNO-10 controllers linked by our DMR-203 radio control interface.
