The Watchman

thingiverse

I added face tracking to the Doorman, creating the Watchman! The eyes will track your face as you move past. I made design changes, most notably to incorporate Google's AIY VIsion board (for face detection) and to incorporate Will Cogley's [Advanced Eye mechanism](http://www.nilheim.co.uk/latest-projects-and-blog/compact-and-robust-3d-printed-animatronic-eye-mechanism.) Video of tracking: https://www.youtube.com/watch?v=xo8RRXo4SKw More detail on what I changed: - Designed face structure to securely package electronics and allow quick access. - Integrated Google's AIY Vision Hat for offline face tracking. - Added batteries for mobile use. - Wrote Python and C++ programs to find faces and direct servo positions. - Adapted and upgraded eye mechanism - using Will Cogley's (Nilheim Mechatronics) advanced eye mechanism. - Designed laser accuracy tuning hardware  - integrated lasers to tune eye mechanism accuracy. The eye mechanism STL's I uploaded are parts that I used instead of the equivalent parts from Will Cogley's eye mechanism. To build this eye mechanism, you should follow Will Cogley's very useful [guide](http://www.nilheim.co.uk/latest-projects-and-blog/compact-and-robust-3d-printed-animatronic-eye-mechanism), and substitute my parts where needed. The face structure prints as a single piece, I printed in PLA and had great results. Safety note: If you make this project and use the laser calibration eyes, don't test with your face! Use a printed photo, drawing, etc to activate the facial recognition. Lasers can cause permanent eye damage. Code for this project can be found on [Github](https://github.com/graham-jessup/Watchman) Read more about this project on my site: https://grahamjessup.com/watchman/
