Six-degree-of-freedom parallel waist exoskeleton with human parameter adaptive function and kinematics initialization method

PendingCN122274919AHuman bodyBody shape
This invention discloses a six-degree-of-freedom parallel lumbar exoskeleton with human body parameter adaptive function and a kinematic initialization method. The exoskeleton uses linear actuators in both assembly and disassembly configurations: in the assembly configuration, one end of the linear actuator is connected to the lower platform and the other end to the upper platform, with the lower platform used to fix to a first target plane and the upper platform used to fix to a second target plane; in the disassembly configuration, the lower platform is used to fix to the first target plane and the upper platform is used to fix to the second target plane; both the lower and upper platforms are composed of two semi-rings; in the assembly configuration, the linear actuators adopt a heterogeneous layout, using two linear actuators with different initial lengths to shift the workspace of the mechanism towards the front of the human body, thereby obtaining a larger range of forward flexion; in the disassembly configuration, it can be used to obtain the desired rehabilitation trajectory; furthermore, after the exoskeleton is strapped in, the method provides a kinematic control model by measuring the physical gap variable between the moving and fixed platforms, reflecting individual body shape differences, and reconstructing it, thereby obtaining the corrected actual coordinates of the hinge points, thus ensuring, to a certain extent, accurate matching between the exoskeleton's motion center and the user's actual motion center.
