ESP32 5+1-DOF Robot Arm Kit RoArm-M3-S with High Torque Serial Bus Servos

With the RoArm-M3-S from Waveshare, you can build your own precise, versatile robotic arm for applications in research, education, or DIY projects. The kit is based on a powerful ESP32 microcontroller and uses seven Serial Bus Servos, allowing you flexible and smooth movement in five axes plus a gripper. The integrated high-torque servos ensure stable and precise movements while maintaining a compact design. Control is wireless via WiFi or Bluetooth, allowing convenient integration into existing systems or remote control via app. The arm is operated using inverse kinematics and user-friendly software, enabling immediate use even without extensive programming knowledge. Thanks to the included graphical user interface, you can easily control positions via drag & drop or execute complex motion sequences. A web interface and support for MicroPython are available for programming. The robust aluminum housing of the joints and the modular design provide long service life and easy maintenance. The software is open source, allowing individual customization of the system. The model is suitable for precise gripping and sorting tasks, experimental automation, and as an introduction to the world of robotics. A wide range of tutorials and demos make entry especially easy. Recommended Accessories: RoArm Gripper Gripper-A Features: The robot arm kit uses a powerful ESP32 microcontroller with integrated WiFi and Bluetooth for wireless control and easy integration. The seven built-in Serial Bus Servos offer high torque and enable stable movements in five axes and precise gripping control. Inverse kinematics allow intuitive control of the end effector position without manually driving individual servos. The software supports MicroPython and offers easy programming through a web interface even without prior knowledge. The mechanical design is based on CNC-machined aluminum parts for high stability and long service life in daily use. An integrated buzzer and an RGB status LED provide visual and acoustic feedback on the operating status. The open-source software offers the possibility to customize the robotic arm to your projects flexibly. Application Examples: Used in educational projects to convey robotics and programming knowledge Automated sorting of small objects on a conveyor belt Gripping and placing tasks in makerspaces or development environments Integration into IoT projects for remote control via WiFi Demonstration and development of AI-controlled motion sequences Documentation: Waveshare Wiki Board Overview: ESP32-WROOM-32 Controller Module Can be developed with the Arduino IDE IPEX1 WiFi Connector For connecting a WiFi antenna to increase wireless communication range LiDAR Interface Integrated radar adapter function I2C Expansion Interface For connecting an OLED display or other I2C sensors Reset Button Press and release to restart the ESP32 Download Button The ESP32 starts in download mode after powering on DC-DC 5V Voltage Regulator Circuit Power supply for host computers like Raspberry Pi or Jetson Nano Type-C Port (LiDAR) For transmitting LiDAR data Type-C Port (USB) Communication interface of the ESP32, for uploading programs to the ESP32 XH2.54 Power Connector Supports DC 7-13V input, can power serial bus servos and motors directly INA219 Voltage/Current Monitoring Chip On/Off Switch To turn on and off the external power supply ST3215 Serial Bus Servo Interface For connecting to ST3215 serial bus servos Motor Interface PH2.0 6P Group B Interface for motors with encoder Motor Interface PH2.0 6P Group A Interface for motors with encoder Motor Interface PH2.0 2P Group A Interface for motors without encoder Motor Interface PH2.0 2P Group B Interface for motors without encoder AK09918C Three-Axis Electronic Compass QMI8658C 6-Axis Motion Sensor TB6612FNG Motor Control Chip Control Circuit for Serial Bus Servos For controlling multiple ST3215 servos and retrieving feedback TF Card Slot For storing logs or WiFi configurations 40PIN GPIO Header For connecting to Raspberry Pi or other host boards 40PIN Expansion Header Facilitates the use of the GPIO pins of Raspberry Pi or other host boards CP-2102 UART-to-USB, for radar data transmission CP-2102 UART-to-USB, for ESP32 communication Automatic Download Circuit For uploading programs to the ESP32 without pressing the EN and BOOT buttons Technical Data: Manufacturer: Waveshare Manufacturer SKU: 30442 Main Control: ESP32 MCU Degrees of Freedom (DOF): 5+1 Working Range: Horizontal Diameter: 1120mm (Max, 360° omnidirectional), Vertical: 798mm (Max) Operating Voltage: 12V 5A Power Supply, supports 3S Lithium Batteries (not included) Payload: 0.2kg at 0.5m Repositioning Accuracy: ≈±5mm (under the same load) Servo Speed: 40 RPM (no load, no torque limit) Operating Range: Base-360°, Shoulder-180°, Elbow-225°, Hand-135°/270° Drive Type: TTL Serial Bus Servo, Direct Drive Joint Number of Servos: 7 (6x ST3215, 1x ST3215-HS) Joint Angle Sensor: 12-bit 360° Magnetic Encoder Servo Torque: 30KG.CM at 12V, 20KG.CM at 12V (EoAT) Joint Feedback Information: Servo Status, Joint Angle, Rotation Speed, Joint Load, Servo Voltage, Servo Current, Servo Temperature, and Servo Operating Mode Main Control: ESP32-WROOM-32 Main Control Module Functions: WiFi, BT, Dual Core, 240MHz Wireless Control Mode: 2.4G WiFi, ESP-NOW Wired Control Mode: USB, UART Manual Operation Mode: Web Control Interface Host Operation Mode: UART/USB/ESP-NOW*/HTTP Communication via JSON Data Format Commands (* Feedback information is not available in ESP-NOW communication mode) Host Support: USB-connected devices including Raspberry Pi, Jetson Orin Nano, and PC.
