What "lunar rovers" did the United States send to the moon?

The United States sent four "lunar rovers" to the moon, the earliest of which was a trolley. The difference is that the American lunar rovers were brought by the astronauts who landed on the moon themselves. On February 5, 1971, two astronauts on the American Apollo 14, Shepard and Mitchell, pushed a two-wheeled cart carrying their tools, instruments and cameras on the moon. A walking survey was conducted on the lunar surface, thus leaving the second human rut mark on the lunar surface. The vehicle also brought back 43.5 kilograms (96 pounds) of moon rocks.

On July 31, 1971, there was a second motor vehicle on the moon - "Rover 1". This vehicle is quite delicate, with a total length of about 3 meters and a weight of 209 kilograms (only 33 kilograms on the moon). The four wheels below are equipped with independent drive motors, making it very flexible. Its tires are made of special rubber and are still elastic even at temperatures of more than 100 degrees below zero. The driver can control the vehicle forward, backward, turn, climb (the maximum gradient is also 30°), accelerate and decelerate, etc. The maximum speed on the lunar surface is 18 kilometers per hour, which is similar to the speed of a fast-moving bicycle. The two astronauts of "Apollo 15" drove it for 27.9 kilometers, conducted multiple research projects on the lunar surface along the way, and collected lunar rock specimens in different places. Subsequently, "Apollo" 16 and 17 also brought lunar rovers, which traveled 27 and 35 kilometers on the moon respectively. These lunar rovers are equipped with television cameras and special transmission equipment. The activities of astronauts on the lunar surface are all sent back from the lunar rovers.
