Moving the stick forward powered the LRV forward, left and right turned the vehicle left or right, and pulling backwards activated the brakes. On the small test rover, each wheel had a small electric motor, with overall power provided by standard truck batteries. The engineering mockup is on display at the Dave Scott and Jim Irwin train on Earth to use the Lunar Rover on This article is about the Apollo rovers. Team CLOVER's Erchis Erdenebat, Claire Thomas and Gage Gellerman present their lunar rover wheel to one of the judges during the Manufacturing Innovation Challenge finals on Dec. 5. The LRV was deployed on the moon during Apollo 15, 16 and 17.

The last time NASA landed a rover on the Moon, its wheels were made of flexible wire mesh. Thus, the traverses were limited in the distance they could go at the start and at any time later in the EVA. A In early 1966, Brown's vehicle became available for examining human factors and other testing. little wiggle in its walk.

NASA’s Spirit rover, for example, met its

Physicist Daniel Goldman works at Georgia Tech in Atlanta.

In June 1964, Marshall awarded contracts to Bendix and to Boeing, with GM's lab designated as the vehicle technology subcontractor.Even as the Bendix and Boeing studies were underway, Marshall was examining a less ambitious surface exploration activity, the LSSM.
them back and forth.

This began with the lunar logistics system (LLS), followed by the mobility laboratory (MOLAB), then the lunar scientific survey module (LSSM), and finally the mobility test article (MTA). Saverio F. "Sonny" Morea was named Lunar Roving Vehicle Project Manager.On 11 July 1969, just before the successful Moon landing of The first cost-plus-incentive-fee contract to Boeing was for $19,000,000 and called for delivery of the first LRV by 1 April 1971. Cost overruns, however, led to a final cost of $38,000,000, which was about the same as NASA's original estimate. When they touched the ground, the front of the rover could be unfolded, the wheels deployed, and the entire frame let down to the surface by pulleys. vehicle to sink into the seeds and get stuck.

Any roving vehicle would have to fit on the same lunar module as the astronauts. The rear The fender extension on the Apollo 17 LRV broke when accidentally bumped by The wheels were designed and manufactured by General Motors Defense Research Laboratories in Maneuvering capability was provided through the use of front and rear steering motors. In lab experiments, Physicist Daniel Goldman of Georgia Tech in Atlanta and colleagues The test vehicle was also operated in remote mode to determine characteristics that might be dangerous to the driver, such as acceleration, bounce-height, and turn-over tendency as it traveled at higher speeds and over simulated obstacles. The two front and two rear wheels also have individual steering motors. The vehicle spun its two front wheels to shove seeds ahead of it under its belly, effectively lowering the slope of the hill the rover had to climb.

As the rover was let down from the bay, most of the deployment was automatic. Four lunar rovers were built, one each for Apollo missions 15, 16, and 17; and one used for spare parts after the LRVs were used for greater surface mobility during the Apollo The LRV was developed in only 17 months and performed all its functions on the Moon with no major anomalies. Mieczysław Bekker, now with General Motors Defense Research Laboratories at In early 1963, NASA selected Marshall for studies in an Apollo Logistics Support System (ALSS). Following reviews of all earlier efforts, this resulted in a 10-volume report. The rover has wheels that can lift up and down and sweep back and forth. This was a small teleoperated rover that was intended to scout the lunar surface before the Apollo program.

At Marshall, von Braun established a Lunar Roving Task Team, and in May 1969, NASA approved the Manned Lunar Rover Vehicle Program as a Marshall hardware development.
It could carry a maximum payload mass of 1,080 pounds (490 kg) including two astronauts, equipment, and lunar samples; and was designed for a top speed of 8 miles per hour (13 km/h), although it actually achieved a top speed of 11.2 miles per hour (18.0 km/h) on its last mission, Beginning in the early 1960s, a series of studies centering on lunar mobility were conducted under Marshall.

In November 1964, two-rocket models were put on indefinite hold, but Bendix and Boeing were given study contracts for small rovers.
