... the fish not handled by the robot. Design/methodology/approach The design approach of the salmonid slaughter line focuses on using 3D machine vision and a bleed‐cutting robot with four biaxial pneumatic actuators to handle the slaughtering of pre‐anesthetized salmon and rainbow trout. Findings...

.... Research limitations/implications The new design reduces the number of actuators used in the robot and increases the magnetic adhesion force. Practical implications Thanks to the excellent passing‐obstacles and payload capabilities, the climbing robot with the new mechanism has a widely applying...

Since the actuator often contributes a significant portion of the module weight, it is interesting to investigate...

... musculoskeletal system” is achieved through the use of the pneumatic artificial muscles. The study provides a novel method to describe the force property of the articulated mechanism driven by muscle actuator and a transmission. Design/methodology/approach A musculoskeletal system consists of multiple bodies...

... actuators. The control system provides independent control for the robot. The joint axes of the robotic arm are arranged to mimic the natural upper limb workspace. Findings Findings are the classification of training modes and control methods of rehabilitation training, and the characters of both...

... robotic devices are relatively complex, large, cumbersome and difficult to be installed in a humanoid robot arm. Under‐actuated robot hands use less motors to drive more rotating joints, thus to simplify the mechanical structure, decrease the volume and weight and finally lower the difficulty of control...
