Bipedalism success of creating a fully passive, un-powered bipedal walking robot, those working on such machines have begun using principles gleaned from the study of human and animal locomotion, which often relies on passive mechanisms to minimize power consumption. Bipedalism Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped , meaning "two feet" (from the Latin "bis" for "double" and "pes" for "foot"). Types of bipedal movement include walking, running, or hopping. Few modern
Animal cognition for spatial location and to discover how an animal is able to determine locations. Typically the maze is a circular tank filled with water that has been made milky so that it is opaque. Located somewhere in the maze is a small platform placed just below the surface of the water. When placed in the tank, the animal swims around until it finds and climbs up on the platform. With practice, the animal finds the platform more and more quickly. Reference memory is assessed by removing the platform and observing the relative amount of time the animal spends swimming in
