Thor is an open source, 3D-printable 6-degrees-of-freedom robotic arm designed to be affordable (under 350€) and accessible for education, makers, and robotics enthusiasts. The repository provides FreeCAD source models, STL/STEP files, a bill of materials, and documentation for printing, assembly, electronics, and GRBL-based firmware control.

Use cases

  • build a 3D printed robotic arm at home
  • teach robotics in schools and universities
  • learn industrial manipulator kinematics hands-on
  • print and assemble a 6DOF robot arm from STL files
  • control a robot arm with G-code like a 3D printer or CNC
  • integrate a DIY robot arm with ROS2 and MoveIt2
  • modify an open source robot arm design in FreeCAD

When to choose

  • you want an affordable, fully open source robotic arm you can print and build yourself
  • you need an educational platform for robotics courses covering CAD, electronics, and firmware
  • you want an industrial-style yaw-roll-roll-yaw manipulator with ROS2 integration
  • you prefer hardware designed entirely with open source tools (FreeCAD, KiCAD, GRBL)

When to avoid

  • you need a ready-made robot that works out of the box - this is a multi-week build project
  • you need to lift heavy payloads beyond 750 grams
  • you require high-precision industrial automation
  • you have no access to a 3D printer or willingness to solder and source electronics
