Meet Otto DIY+, a charming, open-source, bipedal robot that’s easy to build, fun to customize, and packed with playful features. Brought to life by Camilo Parra Palacio and the Otto DIY community, this engaging project combines Arduino, Bluetooth control, and 3D printing to create a robot that can walk, dance, play sounds, avoid obstacles, and respond to touch—all in under a few hours instructables.com+8hackster.io+8forum.arduino.cc+8.
At its heart lies an Arduino Nano paired with metal-geared micro servos for its legs and optional arms. It’s powered by a rechargeable Li‑Po battery and comes alive with mobile connectivity via an HC‑05/HC‑06 Bluetooth module. Attach a sound sensor or touch pad for interactive input—the robot becomes responsive to claps, tap gestures, and even ambient noise instructables.com. The 3D-printed design is thoughtfully optimized for PLA printing with no support structures needed, so assembly is a breeze.
What makes Otto DIY+ especially cool is its balance of simplicity and interactivity. There’s a dedicated app and Bluetooth support, so you can control it from your phone or teach it new routines. For less code-savvy makers, visual programming through Blockly lets you arrange behaviors without typing. More adventurous tinkerers can dive into the Arduino IDE to customize movement patterns, sensor responses, or personality-driven animations.
The underlying design philosophy shines through: Otto is fully open-source and community-driven, encouraging modifications, remixes, and playful experimentation. Join the builder community to share your improvements, post videos, or challenge others to a dance-off. From a STEM classroom teaching basic robotics to a hobbyist's weekend project, Otto DIY+ sparks curiosity and creativity.
If you’ve got a 3D printer, a couple of servos, and a basic Arduino setup, Otto DIY+ delivers a rich robotics experience without being overwhelming. It’s a delightful introduction to mechanics, electronics, programming, and design—all wrapped in a cute, interactive robot. Click here to view the full project ➜
