Meet MANTIS: a multi-limbed walking robot with different gaits that can overcome obstacles and perform various manipulation tasks. The robot has rotational actuators in its arms, legs, and heads. It comes with laser rangefinder, stereo camera system, and temperature/current/tactical sensors.
As the above video shows, this robot can change direction, climb over obstacles, grasp and pick things, and perform tasks in two different postures. It uses its four rear legs for locomotion and 2 front legs for manipulation.
