You do not say whether the robot was functional before you started blowing Victors. It is possible that your code is causing the Victors to rapidly change direction. Although, robots normally encounter reversals, a code error can wreak havoc with the elctronics as they interact with the motors. If you are using multiple motors in a single transmission, are the motors connected properly? Fulll throttle with the motors fighting each other could easily damage the Victors. Were the breakers buzzing? This is an indication of extremely high currents. Causes are improper wiring, shorted terminals, locked transmission, or metal flakes. As others have pointed out, my experience is about 85-90% of all failures are metal flake related.
