Open Source ESP32 Robot Controller

I designed this ESP32-based general-purpose robot controller board to serve as a general purpose, versatile and powerful tool for supporting a wide range of robotics and engineering projects in educational environments. This basic building block was meant to serve as a first step in helping students design all kinds of fun and exciting robotics projects! Designed with four high-power motor drivers (DRV8871), it can efficiently control drive motors, ensuring reliable and precise movement. A dedicated motor driver for active end effectors, such as electromagnets or pneumatic pumps, adds further flexibility for various applications. The board's UART-compatible header pins enable seamless communication with more powerful single-board computers (SBCs), expanding its computational capabilities for complex tasks like AI and machine learning.

Additionally, the board features five sets of header pins for stepper motors or servos, providing support for advanced robotic manipulators or multi-axis systems. Its integration of WiFi and Bluetooth functionality unlocks a host of opportunities, from remote teleoperation to IoT-based automation projects. This robust controller bridges the gap between high-level SBCs and low-level motor control, making it an ideal platform for developing innovative robotics solutions and exploring cutting-edge technologies in education and research.
