Would you consider possibly adding power distribution and wire conectivity to these roboports. Maybe add an additional recipe for one with power distribution and then leave the original without. To compensate for this feature add to it's recipe the number of substations it would take to cover the area serviced by the roboport and then to me anyway it wouldn't really be an overpowered item. I tested it and you would need aprox 36 standard substations to fill the coverage area.
