Grasping is a significant yet challenging task for the robots.In this paper,the grasping problem for a class of dexterous robotic hands is investigated based on the novel concept of constrained region in environment,which is inspired by the grasping operations of the human beings.More precisely,constrained region in environment is formed by the environment,which integrates a bio-inspired co-sensing framework.By utilizing the concept of constrained region in environment,the grasping by robots can be effectively accomplished with relatively low-precision sensors.For the grasping of dexterous robotic hands,the attractive region in environment is first established by model primitives in the configuration space to generate offline grasping planning.Then,online dynamic adjustment is implemented by integrating the visual sensory and force sensory information,such that the uncertainty can be further eliminated and certain compliance can be obtained.In the end,an experimental example of Barrett Hand is provided to show the effectiveness of our proposed grasping strategy based on constrained region in environment.
