Modifications may come


Actuators can be connected to the bones where you find it appropriate. The shape of the bones can be freely chosen. No modification on the central hub or balancing support rod can be made. Both exoskeleton and endoskeleton approaches are welcome

Cylinder-based robots:

  • Overall specifications
    • Max printed volume of pelvis/femur/tibia together : 500ml
    • Robot must be able to contract to a height of 250mm, measured from the floor to the center of the pelvis joint
    • Robot must be able to erect to a height of 400mm, measured from the floor to the center of the pelvis joint
    • Only joint types found in the human body are allowed. Ball bearings are allowed
    • The robot must be able to jump a full round at a speed > 12cm/sec
  • Actuators:
    • Max number of pneumatic cylinders : 4
  • Pelvis:
    • The size can be chosen freely
  • Femur (upper leg bone):
    • Length between center of joints : 200mm
  • Tibia (lower leg bone):
    • Length between top joint center and sole limit circle center : 210mm
  • Sole:
    • The size of the casted silicone sole must be able to fit into a cylinder with a diameter of 50mm
    • No other part of the robot than the sole can touch the ground

McKibben-based robots:

Same as for cylinder-based, except:

  • Jumping speed > 1cm/sec
  • No contract/erect height requirements
  • You can use as many McKibben muscles as you want
