Canonical robot record
Overview
Petoi Bittle is a palm-sized, open-source quadruped robot dog built for hobbyists, students, and educators interested in robotics, coding, and AI. Rather than rolling on wheels, it walks and runs on four legs and can play animal-like tricks, giving it a lifelike, bionic character. It originated from founder Rongzhong Li's OpenCat project and was crowdfunded on Kickstarter before becoming a standard Petoi product.
The robot is sold as a construction kit that buyers assemble themselves, which doubles as a hands-on introduction to mechanical and electronic systems. It is built around an Arduino-compatible microcontroller and includes an inertial measurement sensor, programmable LED lighting, and digital servo joints that drive its gait and posture.
Bittle can be operated with an infrared remote or the Petoi mobile app, and its open-source firmware lets makers program new behaviors using block-based coding, Python, or C++. This openness makes it a popular platform for STEM learning, experimentation, and robotics research.
RoboZaps maintains this record as part of its canonical robotics database. Specs are source-verified where linked; the record compares public facts across manufacturers rather than representing a single robot maker.

Record changelog
- Degrees of Freedom: 9-12 changed to 9 · Jul 8, 2026
tranche-5 verification (corrected): Official spec: 9 powered servo joints (2 per leg x 4 + 1 neck). '9-12' overstates - Bittle and Bittle X are both 9 DOF.
- Battery Life: 30-60 min changed to 1 hour · Jul 8, 2026
tranche-5 verification (corrected): Official spec: 7.4V 1000mAh, 'Battery life: 1 hour'; product page: 'about one hour of continuous walking'. No official 30-60 min range.
- Max Speed: 0.3 m/s changed to 0.4 m/s (2 body lengths/s, safe fast speed) · Jul 8, 2026
tranche-5 verification (corrected): Petoi: 'A safe fast speed is 2 body lengths/second' (2 x 200 mm body = 0.4 m/s; the page's '40mm/second' is an apparent typo for 400 mm/s - New Atlas independently
