This activity takes place in the robot controller. Body The body of a robot is related to the job it must perform. Industrial robots often take the shape of a bodyless arm since it's job requires it to remain stationary relative to its task. Space robots have many different body shapes such as a sphere, a platform with wheels or legs, or a ballon, depending on it's job. The free-flying rover, Sprint Aercam is a sphere to minimize damage if it were to bump into the shuttle or an astronaut.
Some planetary rovers have solar platforms driven by wheels to traverse terrestrial environments.
Aerobot bodies are balloons that will float through the atmosphere of other worlds collecting data. When evaluating what body type is right for a robot, remember that form follows function. It all depends on the job they have to do and the environment they operate in. You probably saw the Jason AUV at work when pictures of the Titanic discovery were broadcast. One area of research suggests that an underwater robot like RoboTuna could propel itself as a fish does using it's natural undulatory motion.
