When a vacuum sucks air out of the gripper, the skin constricts, forcing the origami skeleton to collapse into a narrow funnel. The bunched-up gripper’s rigged interior and rough latex skin help it keep ahold of objects.(***********)(**********)Shuguang Li, a roboticist at Harvard University and MIT, and colleagues plan to present this device at the International Conference on Robotics and Automation in Montreal in May.(***********)(**********)In lab experiments, the soft gripper picked up household objects of various sizes and shapes, successfully glomming onto a smartphone and the handle of a mug, among other things. Whereas rigid robotic hands lack dexterity and might be liable to crush delicate objects, this rubber gripper gently handles fragile items such as soft fruits and wine glasses.(***********)(**********)And unlike (**********************************)other soft robotic hands(********), which struggle to lift heavy cargo, this device could lift up to about (*********************************************************************************************) kilograms — more than (**************************************************************************) times its own weight ((***********************************)SN: 9/(*******************************************************************************************)/(******************************************************************************************), p. 8(************************************)). That ability allowed the gripper to hoist an electric drill and a full bottle of wine. Such a versatile gripping machine could one day work on a factory assembly line or lend a hand around the house.(***********)(******)(*************************************)(**************************************)(***************************************)(****************************************)(*****************************************)(******************************************)(*******************************************)(********************************************)(***************************************)(****************************************)(**********)(*********************************************)ON HAND (**********************************************)A new soft robotic gripper picks up objects of various sizes and shapes without letting heavier objects slip out of its grasp or crushing delicate items.(***********)(*******************************************)(********************************************)(***********************************************)(************************************************)(**********************)(*******************)(**********************)(**********************)(**********************)(******)(******)
