Sus Hinton (@noopkat) released a couple of months ago a library to control OLED screens from Johnny-five:  https://www.npmjs.com/package/oled-js, so I ordered a SSD1305 from Adafruit.

I will like to add a screen to Felix to eventually give some status feedback, but mostly to display/animate eyes. Sort of the way Baxter from Rethink Robotics does it.

To mount the screen I designed two head pieces and cut them with on the laser-cutter.

The head is controlled by two HXT900 servos. One servo rotate the head from left to right and the other to tilts the head. The rotation is to allow the two SHARP 2Y0A21 proximity sensors to scan the room. The tilt is just cute.

Besides the screen and sensors I also added a small piezo speaker.

I’m happy with the result, now time to do the wiring.
