Even with the PTC, motors can burn out under stall conditions. They do not react quickly enough.The Game Development Committee will not allow individual fuses to protect EACH motor. (it's been asked on Q&A). When prototyping, we used fuses to protect our motors, and it worked well. We were able to design the minibot drive to minimize stall potential. Analogous to the Hostbot electrical system, circuits are fully protected with a main breaker and an individual fuse or circuit breaker to EACH motor. The minibot should follow the same wiring protocol as the Hostbot for many reasons, but proper electrical design and consistency across the board are major concerns that have not been addressed.
