Tether Climber Competition
From mechanical design to control systems, this challenge is all about building robotic climbers capable of ascending a vertical tether. Teams must combine precision, power, and adaptability to simulate the vehicles that could travel from Earth to orbit.

Engineering the Climb
The Climber Competition is the headline challenge of WSPEC. It tasks teams with building robotic climbers capable of ascending a vertical tether while transporting a payload using only stored electrical energy.
The heart of the system
As a critical component of the space elevator concept, climbers must be efficient, reliable, and capable of operating in extreme conditions over long distances. Their development involves challenges in robotics, materials, power systems, and control, making them a central focus in turning the vision of continuous, scalable space access into reality.
