Looking at kits where they create robots. I wonder if they can be simplified with wireless power and wireless communication. Maybe the power could be from wireless induction and the signal or mini power from Wifi. This way they don’t need all those wires to work. The robot exterior could then be streamlined.
For the assembly of electronics maybe this could make things much easier and fault tolerant. No broken soldering and more.
So each component would then have a little wireless chip and an induction receiver.
