Abstract
Maintenance robots are needed for the space elevator system in order to keep the system safe. Then, especially, the robots must climb up and down the tether such as a rope and so have self climbing mechanism. The mechanism is one of the key technologies to realize the space elevator system. However, the tether is not fixed and then the tether's movements are unstable. In this presentation, we show our constructed prototype climber model of the space elevator and fundamental experiment results. The climber model has two independent driving wheels for the climb up the long ribbon straightly and will make brief stops at some target positions supposed as space stations.
