Between 1969 and 1977, the Russians launched a series of rovers to the moon.

Lunakhod 1 was the first ever rover to move across the surface of a remote planet or moon.

It looked like a bath tub with a lid and had eight wheels. The lid was a solar array that powered the rover, but it also had a radioisotope power source that kept it warm during the long lunar nights.  The rover performed soil analysis, took pictures and X-rays.
