Spirit and Opportunity are the names of the two most recent vehicles that have been sent to the surface of Mars by NASA. They both landed in January 2004, on opposite sides of the planet. The mission have been a huge success, far beyond expectations. They are still in operation today, way beyond their initial 90 day target, although Spirit became stuck in the sand in May 2009 and is now just a stationary observational platform.
The name of the first robot to explore Mars was "Sojourner". Sojourner was a rover robot. Sojourner weighed 24 pounds on Earth, but only 9 pounds on Mars. This robot was about the size of a child's wagon. Sojourner was a very slow robot. He could only move 2 feet per minute. Even though Sojourner was slow, he was used to complete many tasks.
Comment: It depends how you define a robot. I would say the "Viking" landers were robots, even though they were not able to move around.
In that case "Viking 1" and "Viking 2" were the first robots to successfully land on Mars and do useful work. "Viking 1" was just first, by a short time, ahead of its "twin".
So the answer is, probably, "Viking 1".
There have been several robotic landers and rovers sent to Mars. The ones which landed and deployed successfully are:
Viking 1 (1976)
Viking 2 (1976)
Mars Exploration Rover A "Spirit" (2004)
Mars Exploration Rover B "Opportunity" (2004)
Phoenix (2008)
Of those, only Spirit and Opportunity are still operational.
It might depend on what is intended by "robot". Several landers were motionless but had robotic arms used to sample soil. Several missions intended for landing and surface operations, and at least one intended to be an orbiter, crashed on the surface. One intended to crash (Deep Space 2) may not arguably have been considered robotic, and failed to communicate. As of early 2016, two continue to be mobile and still roam the Martian surface (Curiosity, and Opportunity). A complete list of artificial objects on mars which had at least some robotic capability should include the USSR "Mars 2" "Mars 3" and "Mars 6" (all failed); the United States "Viking 1" "Viking 2" landers, "Sojourner" (from Pathfinder); "Mars Polar Lander" (crashed); "Spirit" "Opportunity" "Phoenix" and "Curiosity" (Mars Science Lab); and the UK's "Beagle 2" which experienced failures. The four with a wheeled design, and which were successfully mobilized, were Sojourner, Spirit, Opportunity, and Curiosity.

As of 2013, humans have not been to Mars.The first man to step on Mars was......... no one, no man has ever been on Mars, only the mars Rover, a little robot like machine that takes pictures and sand samples of the earth like planet, Mars!!
first of all mars rover is a robot... so a robot can only work if it's given a program... and it depends on the program... it could be a program that let's a robot clean serve or whatever... but there's a very huge disadvatage of robot... a robot doesn't have coomon sense, emotion, and decision making... well for our present technology... so that's how hard it is for a robot to work... for a robot... hundred and thousands miles away from earth.... how on earth will the mars rover work... i can imagine a mars rover as a retarded cockroach because take a look at this.... mars rover needs to give program and control every now and then from earth to mars.... imagine how hard it is..... our technology is vvverry primitive... in terms of robotics... but we made a very big progress but still looooooOOOOng way to GO
His name was sojourner.
It is a Mars rover.
a robot
what was the name of the FIRST modern robot ? what was the name of the FIRST modern robot ?
There's a robot on Mars call, "The Mars Rover" if that is what you are talking about
curiosity.
The first rovers sent to Mars were the Russian Rovers,Mars 2 and Mars 3. But, Mars 2 crash-landed on the planet and Mars 3 ceased transmissions 20 seconds after landing. Mariner 4 was the first succesfully landed probe.
just a robot
planet mars udiscy ?
Sojourner, in 1997.
The robot was the first ever to land and explore Mars. But it only worked for days.
