My model is that of a scooter. It can help the astronaut to move from place to place. It can also work more nicely with a solar panel attached to it.
For the convenience of the astronaut, I also attached a tablet panel and there are antennas in case if the astronaut is able to receive signals in space. The parts of the scooter are seat, base and wheels, handle, connectors, tablet holder and antennas.
