Malice Electronics!

Robotic Death Company Weapon Speed Controller

During the 2021 Season our Vex BB motor controller burnt up 3 times and we had to find an alternative!

Malice runs a ME0909 Motor to power our Weapon, this is a massive motor that runs on 12S and 600amp+ peak. There are very limited motor controller options to get something that massive moving a weapon as heavy as ours. There are the old reliable contactors, the Trampa VESC and the Vex BB ESC.

Contactors are great for the old batteries that didn’t have the capacity to dump all their amperage all at once. Since we run lipos, if we used a contactor, we would have our batteries dump their amps and catch on fire (see Tombstones fight against Shrederator for what happens when you use Lipos with Contactors)

The trampa vesc is a great ESC for brushless motors, but when it’s used in brushed mode (what we need for the ME0909) use a very reduced current, and the spin-up time is ATROCIOUS.

The Vex BB seemed like our best option because it had been shown reliable by robots like Bite Force.

Luckily, the amazing folks over at Robotic Death Company have now solved our speed controller problem! We have tested it out and it’s proven to work!!!

Castle Drive Speed Controllers

For our drive, Malice uses castle speed controllers in brushed mode! We use brushed drive motors because for the way we drive, brushed gives us the best control!
