This paper proposes a new 13 degrees of freedom equivalent kinematic model for the human upper limb and fully considers the movement characteristics of human upper limbs in anatomy. The proposed model can be utilized to analyze the human upper limb workspace and joint motions. Furthermore, the model can effectively evaluate the existing upper limb exoskeleton and provide suggestions for structural improvements in line with human motion.

The reconfigurable external fixation based on the seven-link mechanism has configurations in multiple dimensions, multiple postures, and multiple fracture scenarios, enabling rapid and stable fixation of fractures in the femur, tibia, elbow joint, knee joint, and ankle joint. It has been verified that this external fixation has stable structure and reliable fixation and significantly shortens the operation time and can be used for temporary fracture fixation in emergency medical scenarios.

This paper proposes a novel dual-tunnel soft pneumatic origami actuator to provide a large maximum shrinkage rate for reciprocating motion. A programmed design method is proposed based on the geometric parameter model and stiffness model of the actuator. In comparison to other actuators, this actuator weighs only 5 g, and the force-to-weight ratio is 600. The maximum shrinkage rate of the actuator is 61 %, increasing the potential for lightweight and compact devices.

This paper proposes a novel EMG-based motion compensation controller in active training control to improve patients’ active participation. After proposing an upper limb rehabilitation robot and doing the path plan, the EMG compensation experiments and the active training control experiment are done to prove that the method can control the robot in providing auxiliary force according to patients’ motion intents. The robot can guide the patients in implementing reference tasks in active training.

This paper proposes a bionic, multi-posture wheelchair, based on the proposed human–wheelchair coupling model, according to the movement characteristics and requirements. The two key factors in designing the multi-posture wheelchair, the consistency of the motion center and the compensation of the shifting center of gravity, are analyzed in this paper. The novel multi-posture wheelchair can implement the sit-to-lie and sit-to-stand transformations with a maximum slipping distance of 10.5 mm.

This paper proposes a novel, 4 degrees of freedom, end-effector-based upper limb rehabilitation robot with space training. The robot can assist the human upper limb in performing rehabilitation training of the shoulder flexion/extension and adduction/abduction and elbow flexion/extension. Different from the desktop-type end-effector-based robot, the proposed robot can provide a wide range of shoulder flexion/extension training and cover the range of movement of the human upper limb.

Short summary
This paper presents a novel soft bionic elbow exoskeleton based on shape metal alloy (SMA) actuators (Sobee-SMA). The exoskeleton adopts a bionic design, combining active deformation material SMA and high elastic material rubber band to simulate the contraction and relaxation of the elbow skeletal muscle. According to the static analysis of the human–exoskeleton coupling model and experiments, the exoskeleton provides elbow-assisted motion and ensures the safety of the thermal heating process.
