While sick with the flu a few months ago, [CroMagnon] had a vision. A face with eyes that would follow you – no matter where you walked in the room. He brought this vision to life in the form of Gawkerbot. This is no static piece of art. Gawkerbot’s eyes slowly follow you as you walk through its field of vision. Once the robot has fixed its gaze upon you, the eyes glow blue. It makes one wonder if this is an art piece, or if the rest of the robot is about to pop through the wall and attack.
Gawkerbot’s sensing system is rather simple. A PIR sensor detects motion in the room. If any motion is detected, two ultrasonic sensors which make up the robot’s pupils start taking data. Code running on an ATmega328 determines if a person is detected on the left or right, and moves the eyes appropriately.
[CroMagnon] used an old CD-ROM drive optics sled to move Gawkerbot’s eyes. While the motor is small, the worm drive has plenty of power to move the 3D-printed eyes and linkages. Gawkerbot’s main face is a 3D-printed version of a firefighter’s smoke helmet.
The ultrasonic sensors work, but it took quite a bit of software to tame the jitters noisy data stream. [CroMagnon] is thinking of using PIR sensors on Gawkerbot 2.0. Ultrasonic transducers aren’t just for sensing. Given enough power, you can solder with them. Ultrasonics even work for wireless communications.
Check out the video after the break to see Gawkerbot in action.
You’d think an OpenCV approach would be better but actually I like the hysteresis on its delayed response…
Get that thing back aboard the Lexx where it belongs…
Oh wow – I haven’t thought about that show in years. You’re right – this hack would fit perfectly with the aesthetic
Cool!
It reminds about a SF book or novel where some aliens provide free houses, but each room has an eye that was just watching. Those aliens were not the main story line. The eyes were always watching the people, but apparently the eyes never exploit what they saw, in any way. Just always watching.
Does anybody know the title of that SF book?
I would like to see that done to one of these:
https://en.wikipedia.org/wiki/Kit-Cat_Klock
That page needs a GIF.
No, never say that again. It needs a video maybe, but not in the form of a god-awful 256 color, poorly compressed, uncontrollable animated GIF. The web has better ways of showing videos these days, so let’s put GIF in the garbage where it belongs.
A mostly black and whithe GIF, 687 KB. Way smaller than an embedded video and looks acceptable IMHO.
Well, that’s my dose of creepy for the morning.
My daughter agrees!
Eyes should be dim-red, and turn away when you stare at it for too long.
Creepy up to 10.
C-3PO in bondage. Creepy.
I’m thinking inset into a picture – with the eyes glowing red and moving when they did. They would mess up someone’s day.
Here’s the “Opto-Isolator” from 2007, a project by Golan Levin and Greg Baltus:
