Otto is an open-source, Arduino-compatible, 3D-printable bipedal robot that anyone can build, program, and customize to learn robotics, electronics, and coding.
Otto DIY Biped Robot
Overview
Otto DIY is an open source, 3D printable biped robot designed to make learning robotics, electronics, and embedded programming approachable and hands on. The Otto Biped model can walk, dance, react to its environment, and be extended with new behaviors and hardware modules.
Key Features
- Fully 3D printable biped robot body
- Microcontroller based control system
- Walking, dancing, and expressive motion using micro servos
- Obstacle detection with ultrasonic sensor
- Sound output using a buzzer
- Modular and extensible hardware design
- Programmed entirely through Embedr
Hardware Requirements
- Microcontroller board compatible with Otto
- 4x micro servo motors
- Ultrasonic distance sensor
- Buzzer
- Battery and power switch
- 3D printed body parts
- Screws, wires, and basic tools
Software Requirements
- Embedr account
- Otto firmware and project files available in this directory
Getting Started
- 3D print the Otto Biped body parts or use a pre printed kit
- Assemble the servos, electronics, and wiring
- Open this project in Embedr
