Marcus et al,
I have to say that I am concerned about having inverters on carts where no safety ground exists. A simple inverter for a laptop power supply on the surface should not be a problem if all devices are functioning normally and are fully insulated. However, with the lack of safety ground, the potential for contact with exposed metal parts on the robot cart does exist. I must warn everyone that 110 volt wiring can be lethal and should only be considered when under certified electrical supervision.
