A. Introduction​

The Giraffe Follower Arm is an affordable, open-source 5-DOF robotic manipulator designed for hobbyists, educators, and researchers. Built around a lightweight, 3D-printed frame and high-torque Waveshare ST3215 servos, Giraffe offers a perfect balance of robustness, precision, and affordability. The advantages include:

  • Easy Assembly: A comprehensive yet small Bill of Materials (BOM) with a detailed assembly guide.
  • LeRobot Integration: Allows you to teleoperate and teach Giraffe with our servo-less Leader Arm.
  • ROS2-Native Control: Pre-configured packages for simulation, visualization, trajectory planning, and hardware bring-up.
  • Sensory Extensibility: Optional integration with Intel RealSense off-the-shelf webcams for eye-in-hand or eye-to-hand setup configurations.
