Abstract
A robotic limb is described. The robotic limb has a closed tubular casing made of viscoelastic material defining a chamber containing an incompressible fluid. The closed tubular casing has a sheath formed by substantially inextensible intertwined wires. In the chamber there are groups of transverse actuators axially spaced from each other, connected to the sheath and adapted to reversibly contract the closed tubular casing at least partly in the radial direction. The robotic limb also has longitudinal actuators adapted to reversibly contract the closed tubular casing at least partly in the axial direction being connected to each of the groups of transverse actuators.
