A robot build in the MIT Artificial Intelligence Lab -Humanoid Robotics Group

In 1993, after years of research on behavior-based insect robots, Brooks and his team at MIT started to construct a robot shaped like a human. They named it COG, an abbreviation for “cognition,” and also the tooth of a gear. COG was designed and built to emulate human thought processes and experience the world as a human. Brooks and his team further assumed that people would find it easier to interact with a robot and aid the robot in its learning process when the robot could respond in a somewhat human way. Consequently, the machine should have limbs, sensory organs, and a physical resemblance to humans. Unlike other artificial intelligence systems, like medical expert systems, COG was meant to test theories of human cognition and developmental psychology.
