I don't have any non-copyrighted images of Lunokhod to put on this page,
but here are pictures of Lunokhod-3 (yes, Lunokhod-3!),
which is very similar to Lunokhod-2, except its cameras.
Luna-21 landed 15 Jan at 23:35 GMT inside 55-km Le Monnier crater
on the eastern edge of Mare Serenitatis.

Lunokhod's were controlled remotely from Earth.|
This photo shows Lunokhod crew at work.
There were 2 crews working in turn. Shifts were about 2 hours. Each crew consisted of commander, driver, navigator, flight-engineer and high-gain antenna operator.
|Commander:||Nikolai Yeremenko||Igor Fyodorov|
|Driver:||Gabdulkhay Latypov||Vyacheslav Dovgan|
|Navigator:||Konstantin Davidovsky||Vikenty Samal|
|Flight-Engineer:||Leonid Mosenzov||Albert Kozhevnikov|
|Antenna operator:||Valeri Sapranov||Nikolai Kozlitin|
Lunokhod-2 was very similar in design to Lunokhod-1.
It had 8 wheels, each with independent suspension and its own motor and brake. Any wheel could be permanently disconnected from its motor if the motor gets stuck. Lunokhod's could move at 2 different speeds, 0.9-1 km/h and 1.8-2 km/h and turn in motion as well as on the spot. It was possible to go over obstacles up to 0.4m high or holes up to 0.6m wide. Onboard automatics would stop the rover in case of dangerous tilt or wheel blocking or motor overheating. The crew could override the protection.
Lunokhod-2 had 3 low-rate TV cameras and 4 panoramic cameras.
TV cameras could work at different frame rates: 3.2, 5.7, 10.9 and 21.1 seconds per frame
(not frames per second). Their vertical resolution could vary from 300 to 400.
Whatever frame rate was chosen, exposition was always 1/25 sec. to prevent motion blur.
2 panoramic cameras had field of view of ~180° horizontally and 30° vertically.
2 other cameras had field of view of 360° vertically and 30° horizontally and resolution of 500x6000.
