They use radio communication equipment.

The lunar buggies were solar powered vehicles used on the moon, it was mainly to travel faster and explore a larger area of the moon.
There are three Lunar Roving Vehicles (LRVs) left on the moon from Apollo missions 15, 16, and 17
Lunar rover taken to the moon driven around and is still where it was parked. For all the idiots, morons and naysayers who say we didn't go to the moon explain that one!( and the laser reflectors we monitor.)
Three. Not so sure about the names though. The closest I got to the names was Lunar Roving Vehicles (LRV).
The Lunar Roving Vehicle (LRV) was transported to the moon on the Apollo lunar missions. It was folded and stowed on the lunar module, and astronauts assembled and deployed it once they landed on the moon's surface.
It was the Apollo 11 spacecraft, but they landed on the moon on the lunar module.
Those are the vehicles fuel tanks
Rocket ships are vehicles made to operate outside of Earth's atmosphere. Some of the lunar missions also had a lunar rover that was basically a car for the moon where there is no air to run an engine, so it was electrically powered.
Three from the Apollo missions and two from the Soviet Unions Moon Walker program, so five total.
Lisa Davanay has written: 'Design of an unmanned, lunar cargo lander that reconfigures into a shelter for a habitation module or disassembles into parts useful to a permanent manned lunar base' -- subject(s): Lunar bases, Reusable space vehicles
The vehicles used on the Moon were designed with the Moon's gravity in mind. They would not function correctly on Earth. So the answer is that the Moon's gravity affects the lunar rovers in the same way as gravity affects cars and other vehicles on Earth.... it is what keeps them on the surface, and prevents from from floating off into space.
