I'm sure he could contact a supplier that would change the windings for the same price if he went into production mode. So doing this for his prototype doesn't seem unreasonable. He's under a massive time crunch per his school semester to get this project out the door.

Yeah agree. Having to rewind the motors just adds yet another task to the list for someone trying to build this thing.

Also BLDC based motors in bots seem to be popular now, used to be steppers and harmonic drives from what I remember reading.

Idk why electrostatic actuators aren't getting more popular like HASEL and a few papers on ones using fiber pumps come out recently. I suppose the danger that the high voltages present hmmm.

But surely we can replicate muscle fiber actions magnetically, just need some sort of crazy micro manufacturing process to make the magnets.
