Rotary Stewart Platform v2



Stewart Platforms provide the realistic movement necessary for flight simulators, and are also used in robotic surgery. Normally they are only seen in universities, because students have to build custom machines for specific applications. As part of Raising Robot Literacy, we believe in making a standardized and affordable robot available "off the shelf". Making robots more accessible to more people, and helping to promote their use and understanding.


  • 1500g static holding force (worst case, tested to failure)
  • +/-20 degrees pitch & roll (theoretical max)
  • 10 degrees yaw (theoretical max)
  • +/-40mm heave, surge, and sway (theoretical max)
  • Runs on GCODE. Understands G00,G01,G
  • Limit switches & homing (G28)
  • Measures 165mm across the top, 230mm across the base, 190mm high at rest, ~230mm at center position
  • Weighs ~1650g. 150g less and it could carry a copy of itself!

Mounting holes on top plate have been planned for an extra 7th axis (full yaw rotation).
