Robot learns to play Connect Four.
A French team has taught the Nao robot to play Connect Four.
The robot understands voice commands, and has facial tracking to recognize the emotion of its opponent.
The relative size of the board is huge compared to the two foot robot (think of a playing on a board five feet tall), and Nao must stand back a bit to get an accurate picture with the camera in its eye. The proximity does not allow for stereoscopic vision. Once the board is accessed, Nao must track a complex series of data from its inertia sensors and motors to understand the kinematics necessary to place the piece correctly in the slot.
