AI Technical Summary
Traditional rigid robotic arms suffer from significant damage and insufficient gripping stability when grasping fragile items and complex curved surfaces. Soft robotic arms have limited longitudinal gripping range and are flexible and easily deformable, making it difficult to meet the gripping requirements of complex curved surfaces.
Design a variable stiffness soft manipulator suitable for grasping complex curved objects. The manipulator uses a magnetorheological damper with magnetorheological fluid to achieve variable stiffness of the soft finger. Combining lateral and longitudinal grasping designs, the manipulator utilizes a pneumatic drive and rope transmission mechanism. The stiffness of the soft finger is changed by controlling the on and off of the magnetorheological damper.
It improves the gripping stability and load capacity of the soft robotic arm, enhances the gripping force on complex curved objects, and meets the rigidity and stability requirements of the gripped objects.
