Children and parents waited to have a chance to work with a robot. Orbiters, landers and rovers have all been used to explore Mars. But the NASA rovers, Spirit and Opportunity, are the closest things we have to the space robots of science fiction.
The rovers were launched in two thousand three. They can think for themselves in a limited way.
Spirit and Opportunity have wheels, an arm and camera eyes. Spirit stopped operating in March. But Opportunity continues to communicate with Earth. Both have traveled across many kilometers of the Martian surface performing experiments along the way.
VOICE TWO:
On Mars Day, hundreds of people waited for their chance to use robot technology. Dan Grunberg is a student at the University of Maryland. He has been working on Mars Day for four years. He supervised the two robot activities.

DANIEL GRUNBERG: “I’ve always loved working with the robots. And when I first started it was a challenge working with the robots, understanding how they worked and figuring them out. But over time, we slowly got used to it and we try to make it as kid friendly as possible because kids are what we gear towards and they’re the most important people that come through.”
VOICE TWO:
In one activity, children try to get a robot arm to pick up a block and place it in a cup.
