Product Details
＋
BiBoard is a four-legged robot ESP32 microcontroller board developed by Petoi. With a high-performance processor, larger memory and storage, and wireless connections, it is mainly designed for developers and engineers working on multi-degree-of-freedom (MDOF) Multi-legged robots with up to 12 servos. An audio function is also included.
Features
- drive 12 PWM servos
- an IMU (Inertial Measurement Unit) is used for detecting body status (orientation and acceleration) to balance
- Infrared remote controller
- 3 sockets for external modules.
- USB Type-C port for uploading firmware and serial communication.
- 64Kbit I2C EEPROM
- DAC and audio application.
-
- Built-in connectivity support
- Serial
- Bluetooth
- WiFi
- Compatible with Petoi open source quadruped robotics kits such as and
- Raspberry Pi support - the board also provides a 2×3 socket for mounting Raspberry Pi. You should use wires or adapters to mount the Raspberry Pi on the BiBoard, instead of mounting directly. The Pi allows robotics kits such as Bittle to analyze more complex sensory data, connect to the Internet, and make decisions by itself
The source code is open-source on with a detailed .
Example application
- Petoi's bionic robot dog Bittle fully utilized BiBoard to coordinate 8 degree-of-freedom(DOF) sophisticated motions
- Bittle walks over an 8.5cm(3.35 inch) gap. More details from .
