The robots should be able to use inductive charging to recharge, that would eliminate the power port and also make it easier for them to recharge themselves....You could set a condition that if it's battery drops below a certain level it would find it's dock and recharge.....the inductive part (LOL not so sure about the technical aspects) could be in the feet or underside the robot would basically just have to stand or sit in the right spot, no need to line up jacks or anything like that!!
