Description

Waveshare High-torque Serial Bus Servo Desktop Robotic Arm Kit is a compact desktop robotic arm platform designed for robotics education, motion control development, automation demos, and ROS based experimentation. It is built around an ESP32-WROOM-32 controller and uses high-torque serial bus servos to deliver flexible movement, wireless control, and multi-mode operation in a relatively compact 5-DOF desktop form.

This EU version includes the RoArm-M1 arm set and a 12V 5A EU power supply. The arm combines a stainless steel gripper, carbon fiber arm, and aluminum body, and supports multiple control modes such as angle control, coordinate control, leading-following, and motion recording and replay. It can also connect to Raspberry Pi 5, Jetson Nano, and PC for more advanced robotics workflows.

Features

• 5-DOF robotic arm design including gripper control.
• ESP32-WROOM-32 main controller with WiFi, Bluetooth 4.2, and ESP-NOW communication.
• High-torque serial bus servos for controlled multi-joint motion.
• Multiple control modes including angle, coordinate, leading-following, and motion recording with replay.
• Host compatibility with Raspberry Pi 5, Jetson Nano, and PC through USB.
• Cross-platform web application and ROS 2 demo resources for development.
• Durable mechanical structure using stainless steel, carbon fiber, and aluminum.
• Onboard OLED screen, RGB LED, Type-C, and UART circuit for debugging and status display.
• Servo torque lock control for more flexible manual positioning and teaching workflows.

Other Content

Onboard resources are already integrated, including the ESP32-WROOM-32 main controller, OLED screen, RGB LED, Type-C, and servo control circuitry. This makes the kit more convenient for rapid robotics experiments than a bare mechanical arm requiring a separate controller stack.

Flexible control methods are one of the key strengths of the RoArm-M1. Waveshare specifically highlights leading-following control, torque lock on/off, and position recording with step replay, which are useful for teaching, demonstration, and motion tuning.

Mechanical structure also matters here. The combination of stainless steel gripper, carbon fiber arm, and aluminum body is one of the main reasons this arm is positioned as a stronger desktop kit instead of a toy-grade robotic arm.
