ESP32 5-DOF Open-Source Robotic Arm RoArm-M1

The RoArm-M1 is a versatile, open-source robotic arm based on the ESP32 platform, offering 5 degrees of freedom. With high load capacity thanks to the 30kg.cm strong ST3215 servo, it is ideal for a wide range of applications, from precise motion sequences to control via a Raspberry Pi or other computers. Thanks to flexible control modes, such as angle control or coordinate control, you can program the arm precisely to your needs. The robotic arm also supports wireless control via WiFi or ESP-NOW, making it particularly flexible in application. With extensive ROS-2 integration and support for multiple host computers, you gain a wealth of development and learning opportunities. The RoArm-M1 is equipped with a stainless steel gripper, a carbon fiber arm, and an aluminum housing, making it both robust and lightweight. Perfect for anyone looking for an affordable, high-performance robotic arm.
