The invention discloses a reversible
impact-resistant mechanical arm and a driving method thereof. The reversible
impact-resistant mechanical arm comprises a
humerus-imitating module, an
ulna-imitating module, a
radius-imitating module, an
actuator mounting block and a mechanical arm driving module, wherein one end of each of the
ulna-imitating module and the
radius-imitating module is connected with the
humerus-imitating module, and the other end of each of the
ulna-imitating module and the
radius-imitating module is connected with the
actuator mounting block and used for driving the
actuator mounting block to swing and turn over, the
humerus-imitating module comprises a humerus rod, the ulna-imitating module comprises an ulna rod, the radius-imitating module comprises a
radius rod, the inner ends of the ulna rod and the
radius rod and different positions of one end of the humerus rod respectively form spherical pairs, the outer end of the
radius rod is hinged with the actuator mounting block, and the outer end of the ulna rod and the actuator mounting block form a spherical pair. By adopting the humerus-imitating module, the ulna-imitating module and the radius-imitating module, the reversible
impact-resistant mechanical arm not only can realize buckling and stretching movement, but also can realize inward rotation and outward rotation movement.
