Speak engineering to them. Tell them that first implements a single point dedicated ground which uses dedicated wires as the return path instead of the robot frame. There isn't an awful lot of noise to begin with, some of it is managed by using a twisted-pair, and we are allowed to use small capacitors for sparking motors.

Many of our systems are noise resistant to begin with, for example PWM, which doesn't depend on the voltage but the signal timing which is inherently RF noise resistant. Our motors don't really care what's riding on the DC signal from a jaguar for example. If they are car guys then they should also know that we use CAN bus technology.

Compared to even a 1960s automobile our robot wiring is actually quite simple.
