Challenging hard-arm assisted manipulators to achieve anthropomorphic movements.

　　For many years, research has been devoted to the gripping and other operations of hard-arm assisted manipulators, rather than to better implement gripping, transferring and sorting. This remains a huge challenge for most hard-arm assisted manipulators to achieve anthropomorphic, flexible grasping and squeezing. In addition, anthropomorphic manipulators have very complex mechanics and require complex control systems to be designed to enable their flexible control. At the same time, a variety of sensor information can be used, but there is still no guarantee of reliability and safety, which severely limits the widespread use and commercialisation of flexible anthropomorphic manipulators.

　　Its safety advantages in unstructured environments such as hospitals and homes allow it to play an important role in handling delicate work tasks. Test results have shown that manipulators can safely manipulate fine objects and interact with their environment.

　　Conventional parallel jaw grippers handle fine objects because of insufficient stiffness and flexibility. Other dexterous, rigid arm-assisted manipulators tend to have bulky fingers, rely on transforming wire plates at complex times or are too expensive.

　　Inspired by biology, one researcher has proposed a spiking neural network for controlling the soft grasping action of robotic hands. This control system uses SVH5 to point the hand and grasp objects of formlessness, size and stiffness.

　　In unstructured environments such as hospitals and homes, robots need to be able to perform dexterous manipulation tasks, such as handling pills, coins or other small fragile objects. Many existing robotic end-effectors are specifically designed for industrial applications, with a focus on repeatable, robust manipulation of large, rigid objects. These end-effectors can exert large forces, making them prone to damaging small, delicate, non-rigid objects such as berries and poker.

　　Interest in soft and rigid arm assisted manipulators has recently increased due to their safety advantages. At a conference in the field of robotics, a school presented a pair of manipulators equipped with high-resolution tactile sensors that allow flexible manipulation of cables, wires and other deformable objects.

　　Robots are widely used in a variety of industrial manufacturing and packaging processes for picking and placing tasks with great efficiency and accuracy. However, their use in other applications has not been extensively studied. In particular, many collaborative robot arms used in academia and industry are equipped with two-finger parallel jaws or vacuum jaws. Some laboratories and companies use very expensive and complex anthropomorphic (human-like) hands, but they are often difficult to control independently because of their high degree of freedom. Other researchers have developed their own hands, such as soft air grips or interference grippers, but usually with small working spaces and low accuracy.
