Geometry and mechanical function of multijoint extremities from mammals to insects: towards biomimetic design of robotic arm

Proccedings of 11th International Conference Biomdlore 2016, 2016
Biomechanics of legs of different families of insects is studied. Geometry of different pairs of legs designed for walking, running, swimming, digging and other tasks has been measured on entomological collections. Relationships between the lengths of three main segments (femur, tibia, tarsus) as well as their smaller segments (if any) have been ...
