Add a Humanoid Head to your EZ-Robot so it can recognize its surrounding and display emotions. Includes a built in 640x480 resolution camera for vision tracking with the ARC software. The eyes include 18 RGB LEDs to display expressions in thousands of custom colors. The two metal gear mini servos operate the neck movements in horizontal and vertical directions.
