This clip shows some 1995 footage of Cog interacting with Prof. Rod Brooks. The robot is attending to visual motion, and orienting its head and neck toward that motion. The arm and hand motion shown in this clip are simple repetitive motions which are not interactive.

One of the large sensori-motor integration tasks that has been implemented on Cog so far is the ability to reach to a visual target. Cog learns this task by trial and error. The first video clip shows the robot attempting to reach to where it is looking without any learning. Notice that the hand and eyes end up in very different positions.
