Programmable 4DOF robotic arm kit with ESP32 control delivers hands-on STEAM learning for Arduino and MicroPython projects, featuring joystick and web app control for easy, precise manipulation and quick assembly

ESP32 4-DOF Robot Arm Kit (single unit) for easy USB control
✔️ 4 MG90S servos, ESP32-C3 board, joystick & Web App control

This compact desktop robot arm kit is designed for hands-on STEAM education. It uses four MG90S servos to enable four axes of movement and a claw capable of picking up light items. The ESP32-C3 board is pre-programmed for quick setup, so you can start experimenting without uploading code. Control is available via a joystick or a web app, with mode switching at the press of a button. An onboard battery holder and USB charging keep it portable, and the kit includes Arduino and MicroPython documentation to deepen programming skills.

✅ 4 MG90S servos provide four degrees of motion for precise movement
✅ Pre-programmed ESP32-C3 control board for plug-and-play setup
✅ Joystick and Web App modes switch with a press of a button
✅ Onboard battery holder and USB charging for portable use
✅ Step-by-step assembly tutorial included for quick build
