This application belongs to the field of wearable robot technology, specifically providing a mechanical load-bearing exoskeleton system based on ground reaction force self-triggering. The exoskeleton system includes an upper body mechanism, a thigh mechanism, a knee joint mechanism, a lower leg mechanism, and a foot mechanism. The knee joint mechanism includes a knee joint support, a locking component, and a transmission assembly. When the foot mechanism touches the ground and the sole of the foot is compressed and deformed by the ground reaction force, the thigh mechanism slides downward relative to the knee joint support. The transmission assembly drives the locking component to slide towards the thigh mechanism and connect with it, thereby locking the knee joint mechanism. The compression deformation of the sole of the foot caused by the ground reaction force is used as a trigger signal to automatically trigger the locking of the knee joint mechanism. The knee joint mechanism can lock at any reasonable angle, so that when the wearer is going up or down slopes, climbing stairs, or bending their knees for cover, the exoskeleton system can still effectively assist the human body in bearing the load by locking the knee joint mechanism.

This invention discloses a method and system for adjusting assist parameters of wearable robots based on a biomechanical model, relating to the field of wearable robots. It addresses the current problem that wearable robots cannot intelligently adjust assist torque and damping coefficient. The method involves: constructing the standard deviation of the single-step cycle and the standard plantar pressure range for the wearer's legs; selecting the initial assist torque and initial damping coefficient when the wearer uses the wearable robot based on the difference values; analyzing the plantar pressure at different time points after the wearer uses the robot; analyzing whether the wearable robot needs adjustment based on the actual plantar pressure and the actual single-step cycle standard deviation; and adjusting the initial assist torque and initial damping coefficient of the wearable robot based on the plantar pressure deviation rate and the single-step cycle deviation rate. This invention achieves adaptive adjustment of the wearable robot's assist parameters based on plantar pressure deviation data and single-step cycle deviation data.

This invention provides a multimodal perception and pose calculation method for industrial wearable robots, comprising: acquiring joint inertial data collected by an inertial measurement unit and image sequences collected by a visual sensor; constructing a human kinematic chain model; estimating human pose from the image sequences and outputting the visual pose and confidence level of each joint; when the visual pose confidence level is lower than a threshold, using the nearest reliable visual observation point as the end effector constraint and the joint angular velocity as the driving force, predicting the pose of the occluded joint through forward kinematics recursion; when a high-confidence visual pose of the end effector is detected, the residual between it and the predicted pose of the end effector obtained through recursion is backpropagated to the upstream joints through inverse kinematics calculation to correct the accumulated angular displacement error; adaptively weightedly fusing the visual pose and predicted pose of each joint to output the final human joint pose. This invention effectively solves the visual occlusion problem and improves the continuity and accuracy of pose output.
