Friction forces play an important role in analysis of robotic contact tasks. In most of related studies, only ??local?? constraint on friction forces imposed by, for example, Coulomb's law is considered. However, when contact forces are indeterminate, such local constraint is not enough to assess possible friction forces appropriately. Although Omata and Nagata derived additional ??global?? constraint...
Snakes utilize irregularities in the terrain, such as rocks and vegetation, for faster and more efficient locomotion. This motivates the development of snake robots that actively use the terrain for locomotion, i.e., obstacle-aided locomotion. In order to accurately model and understand this phenomenon, this paper presents a novel nonsmooth (hybrid) mathematical model for wheel-less snake robots,...
