Locomotion is an important factor of astronaut support robots for construction, repair, or inspection. The requirements for it are long reach, smallness, and lightness. Tethers are good candidate because they can make long reach and are very light. They are also compact when they are reeled up. The authors have proposed a re-configurable tether-based locomotion method. In the concept, the robot...

In order to assess functional skills of older adults, both timed up and go (TUG) test and gait speed (GS) test are well validated concerning their predictive capacities. However, the question remains unclear which one of these tests represents better the whole physical performance of older adults. The aim of this study is to determine the more representative test, between TUG and GS, of the who...
