According to some scientists, robots are defined as machines that can interact with their environment and have some abilities to make decisions on their own. In this segment adapted from Curious, robots are also viewed as machines that perform tasks that humans can't (or won't) undertake. One example of a robot is the Mars Rover, an autonomous robot (one that can make some of its own decisions) that was designed to study the past history of water on the ground surface of the planet Mars. LAGR stands for Learning Applied to Ground Robotics, a program that is designed to teach robots how to learn, starting with the human senses.
