Rudy: Final Edition (V3) by marceuxcroix

Last crawled date: 3 years, 3 months ago

Rudy the Really Rude Robot is a proximity sensing robot that responds to proximity by rotating its face away from proximity while flashing a NeoPixel RGB LED strip and playing various sounds. Rudy is based on an Arduino Nano clone and uses a GA12-N20 DC motor, an HC-SR04 ultrasonic sensor, and an active tone generator.
While Rudy V1 features a printed shell, Rudy V3 (and V2) uses a cast acrylic lamp shade. The lamp (https://www.homedepot.com/p/Alsy-8-in-Color-Changing-LED-Glow-Ball-Lamp-19237-000/205208125
) was purchased at a local Home Depot; identical lamps under different brand names can be found online. Rudy's lower chassis is designed to screw into pre-existing threaded holes in this lamp's shade. All other electronics from the lamp are not used as part of this project.
Due to the build-to-build tolerances associated with drilling out the holes for the ultrasonic sensor, the armature that holds the sensor in place is not modeled in and needs to be built manually. The bracket that holds the ultrasonic sensor has allowances for bracket attachment. I also used a small breadboard to connect Rudy's electronics to one another. This is not necessary although I recommend it; the design has a space allowance for a small breadboard as located in the thing images.
Finally, the GA12-N20 draws about 15 milliamps when rotating. It is not generally best practice to drive a DC motor directly from the output pins of any Arduino but the low power requirements of this motor fall well under the max per-pin output (40 mA) of the Nano.
Rudy is now complete. Previous versions of Rudy are all published on Thingiverse under my username.
