Small creatures have inherent mobility problems due to their stride limitation and small body size compared to surroundings. Meanwhile, some of them, such as locusts and fleas, have evolved to acquire better mobility by employing saltatorial (jumping) locomotion. In the similar context, the mobility of small-scale robots can be improved by jumping. To date, several small-scale jumping robots ha...

A number of recent studies have examined the effect of installing physical barriers or otherwise restricting access to public sites that are frequently used for suicides by jumping. While these studies demonstrate that barriers lead to a reduction in the number of suicides by jumping at the site where they are installed, thus far no study has found a statistically significant reduction in the l...

The aim of this study was to quantify internal joint moments of the lower limb during vertical jumping and the weightlifting jerk to improve awareness of the control strategies and correspondence between these activities, and to facilitate understanding of the likely transfer of training effects. Athletic men completed maximal unloaded vertical jumps (n = 12) and explosive push jerks at 40 kg (...
