It's a pity, really. I wouldn't mind having a 'hard' emergency switch that would disengage the motor should our arm extend past the end. My fear, perhaps ungrounded, is that a failure in software will allow a failure in hardware. I've seen too many test stands destroy themselves because the motors were instructed to go when the hardware was maxed out.

Test, test, test again
