218 MOVING YOUR ROBOT

• Hydra robots combine two or more locomotion styles into one. For example, the robot
may use articulated legs with wheels or small tracks as feet. Other types of hydra robots
may combine the functionality of two front legs to serve as a gripper. The name hydra
comes from Greek mythology; the Hydra was a beast with seven heads, who guarded the
entrance to the underworld.
• Unpiloted underwater robots use various propulsion means, such as propellers and thrust-
ers, to move around in fresh and saltwater.
• Similarly, unpiloted flying bots are scale versions of planes and helicopters.
