I know, you are probably thinking "We just gave them a miracle and they still aren't satisfied."
But, seriously, just a suggestion:
We now have a simple snap together piece added on to each module. Now, we need a simple three pin electrical part that will send the signal up from the gripper and wrist and elbo and shoulder to the EZB. I hope I am making it where you could understand it. But, why not have a connector that will not require any wires, just a snap and it will have voltage and ground and maybe have more than one signal on the little snap part. Then you would have no wires to get tangled, smashed, crossovered,unplugged.
Hard to explain what I see in my minds eye. But, WIRELESS SNAP TOGETHER PARTS. Not exactly wireless signal, but the circuit built in to the bracket or servo.
You could do this easily if you had some conductive plastic.
