Abstract: The invention discloses a bionic wrist joint based on an asymmetric 3-RRR parallel mechanism, including: an asymmetric 3-RRR parallel mechanism and a drive unit. The asymmetric 3-RRR parallel mechanism includes: a moving platform, a first static platform, and three asymmetrically distributed parallel branch chains, wherein each branch chain includes a passive rod and an active rod. An end of the active rod is connected to the first static platform via the revolute pair, and another end thereof is connected to the passive rod via the revolute pair. The axes of the revolute pairs at two ends of the active rod form an axis included angle. Three axis included angles are different, the passive rod and the moving platform are connected by the revolute pair, and three axis included angles corresponding to the passive rods are different. The drive unit is configured to drive the asymmetric 3-RRR parallel mechanism to move.

Abstract: A passive exoskeleton based on energy flow characteristics of a foot-ankle complex includes a first passive exoskeleton. The first passive exoskeleton includes an energy distribution mechanism, a strike-recipient mechanism and a wearing fixing assembly. The energy distribution mechanism is connected to the strike-recipient mechanism, and the energy distribution mechanism is also connected to the wearing fixing assembly. The energy distribution mechanism includes a ratchet wheel shaft, a left torsional spring, a right torsional spring and a middle guide wheel respectively sleeved on the ratchet wheel shaft. The middle guide wheel is connected to the wearing fixing assembly through an ankle joint power-assisted cord. The ratchet wheel shaft is connected to the strike-recipient mechanism, the strike-recipient mechanism drives the ratchet wheel shaft to rotate, and the ratchet wheel shaft drives the left torsional spring, the right torsional spring and the middle guide wheel to rotate.
