Overview
The Waveshare RoArm-M1 is a compact 5-DOF desktop robotic arm built around the ESP32-WROOM-32 microcontroller. It uses high-torque ST3215 serial bus servos (30kg.cm) and features a carbon fiber and aluminum body with a stainless steel gripper.
Key Features
- 5 Degrees of Freedom including gripper clamping
- Multiple Control Modes: Angle control, inverse kinematics coordinate control, motion recording/replay, and lead-follow mode via ESP-NOW
- Wireless Control: Built-in WiFi and Bluetooth 4.2 for remote operation via web application or JSON/HTTP commands
- Cross-Platform Web App: No software installation required — control directly from any browser
- ROS 2 Support: Includes URDF model files and ROS 2 demo packages
- Onboard OLED Display: Real-time status monitoring
- RGB LED Indicators: Visual feedback for arm state
- 1:3 Reduction Group: Timing pulley system on main arm for enhanced torque
