Forums user Gucabe took over 18 months to build this awesome astromech droid, which he’s continually upgrading and adding additional features to. An inspiring build for sure!
Hi, ever since I was a little kid I fell in love with R2-D2 and have always wanted to have one of my own. 30 something years later I joined the R2 builders club and started working on my own astromech droid. Took me one and a half years to complete it, well to certain extent. A project like this is never realy done, you always add more and more stuff. But here is what I have so far.
His name is R4-Y0 (aka “El Rayo”) and he is an imperial astromech droid.
Main body controller: Arduino Uno. Has the main program to control the movement, sound triggers, servo signals and serial communication to daughter boards.
Dome controller: Arduino pro mini. Communicates with main controller and controlls the lights
Coin slot sequence: Trinket pro. and leds
Data panel: Trinket pro. led matrixes and neo pixels
The utility arms are servo driven and Im using the Adafruit metal gear servos along with the adafruit servo expander.
I am also using the adafruit 2mb sound board to add additional sounds. Main sound board is from a different source since I needed to use an SD card.
The control is done using a wireless ps2 controller and dongle. Connected directly to the Arduino.
This video is great because the ‘droid uses a sound board to emulate ‘motor sounds’ to make it a little more, well, droid-y!
And here are more quick clips, showing the data panel:
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
