Zoe The Robot
Zoe's Head

Video Camera, Ultra-sonic range finder and an I.R. range finder.


U.S. = Ultra-Sonic
I.R. = Infra-Red
Zoe's head is mounted atop a Servo city SPT200 Pan & Tilt kit
Available at https://www.servocity.com/spt200-pan-tilt-kit/
Zoe's head is moved by Hitec Servos part number HS-645MG

The powerful HS-645MG is one of Hitec’s most popular servos. It’s the perfect choice for those larger sport planes or monster trucks and buggies requiring a durable high torque servo. Featuring their unique M/P and metal gear train technology, the HS-645MG offers one of the strongest gear trains available in any servo.

2. Image Missing   IMG_0238.JPG  Similar to the computer section, the head has 8 sides, but it is not a "perfect" octagon.
I wanted places to mount 8, I.R. sensors, but not exactly at 45 degree increments.

This shows the top of Zoe's head, before paint. Her nose is pointed downward.
3. Image Missing    IMG_0242.JPG Nose is pointed downward. This shows head, body and computer section.
4. Image Missing     HeadInside.JPG    The top and bottom of the head is made from "foam core" board, reinforced with wood.
Inside the head are wires for the I.R. sensors, the Video Camera and an ultrasonic sensor.
I'm going to try mounting a GPS receiver in the head also.
The software may be able to move the head to obtain a better GPS signal.
The head is mounted on a 3 axis, (pan / tilt / wobble) mechanism - with servos controlled by the computer.

The "Head/Neck" servos are NOT controlled by the R/C receiver. The robots software controls the head based on items detected by the sensors, or the software will move the head to point the camera or sensors to check the robots path, or to indicate confusion. (head wobble)
