Sphero R2-D2 Teardown by @Mindtribe: Potentiometer Encoder, Hall Effect Sensors, STM32F MCU, & More! | #StarWars
Check out this teardown by Mindtribe of the Sphero R2-D2 ‘bot highlighting some pretty expected and unexpected sub-circuits, basic components used in novel ways, and overall design & engineering choices:
The Star Wars series has garnered attention for multiple generations. The revolutionary special effects, dramatic storyline, and personable characters have made it a staple in the sci-fi community. Connected toymaker, Sphero, set out to replicate one of Star Wars’ fan-favorite characters – R2-D2.
Sphero’s inclusion of realistic sound effects and interactive motion controls give this toy a personal experience for users of all ages to enjoy. Their custom application enables users to control R2-D2, driving home Sphero’s mission to revolutionize connected play.
After “toying” around with R2-D2 in the office, we wanted to get an inside look at the electronics that made R2-D2 possible. While our partner, Fictiv, did a great job detailing the mechanics, we took an electrical view and analyzed the electronics, architecture, and “smarts” that made R2-D2 a reality. Take a look!
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.
