Petoi Programmable Quadruped Robot System
They move with four legs rather than wheels. Legged motion gives them more freedom to navigate unstructured terrains, and expresses the joy of life whenever they move. Such dynamic maneuverability was only seen on a few luxury robots from the best labs or tycoon companies previously, such as Boston Dynamics Spot or Sony Aibo. Petoi Programmable Quadruped Robot System
- Petoi robots are brought to life by assembling its puzzle-like frames and configured & remote controlled via Petoi mobile app.
- They are programmable via C/C++/Python.
- They have dynamic agile maneuverability and gaits that are performed like real four-legged animals.
- With our customized Arduino board coordinating all instinctive and sophisticated movements, you can clip on various sensors to bring in sensing and perception.
- Inject artificial intelligence capabilities by mounting a Raspberry Pi or other AI chips through wired/wireless connections.
- Built on the popular open source robotic pet framework OpenCat , Petoi robots acts as an open platform for any robotic dream.
- Petoi robot pets makes a perfect tool for learning, teaching, researching, or a surprising gift to impress your family and friends.
System Overview
To solve the varies challenges and strike a fine balance of cutting-edge technology and cost-effectiveness to fit in a compact form factor that can be commercialized, affordable, and mass-producible, we've designed and engineered a robotic system of five major components: body frame, actuator, electronics, power source, and the software to coordinate all the hardware to perform varied tasks.
Actuators
A great actuator is the core of any quadruped walking robot. As the pioneer in mini quadruped robots, we found no off-the-shelf servos when we started to produce our products. So we first ODMed a precise servo with perfectly tuned PID to meet the challenges of powerful, fast yet stable quadruped walking for Nybble. For the second product Bittle, working with the factory from the very first day with many iterations, we designed a brand new servo P1S that's slim and fast with a controllable angle of 270 degrees.

Electronics
Petoi robots are driven by NyBoard V1, a customized Arduino board with rich peripherals. We fully utilized the chip of a regular Arduino Uno to coordinate sophisticated motions. The board can drive at least 12 PWM servos, and an IMU (Inertial Measurement Unit) is used for balancing. It stores "muscle memory" and detects body status (orientation and acceleration) for balancing. We provide an infrared remote to trigger basic movements. The board also listens to string commands from the serial port, such as "walk", "sit", or more detailed instructions for individual joints.
