The invention provides a multi-mode soft
robot based on a bistable structure and a using method of the multi-mode soft
robot, and belongs to the technical field of soft robots. The
robot has two working
modes of quick grabbing and wriggling and
crawling. According to the structure, a lower elastic plate is fixed in a groove of a connecting base, an upper elastic plate and the lower elastic plate are connected through a symmetrical hinge, the upper elastic plate and a top plate are also connected through a
rotating hinge, and four sets of elastic plate-hinge structures are evenly arranged along the circumference. And when the robot is in the rapid grabbing working mode, the top plate is pressed to move downwards, when the acting force exceeds an energy threshold value, the robot can rapidly jump from the first
stable state to the second
stable state and capture the object, and the air bag is actuated to be inflated to release the object to restore the initial state. And when the robot is in the wriggling and
crawling working mode, the robot takes the second
steady state as the initial state, and the single-side actuating air bag is repeatedly inflated and deflated, so that the robot advances in the corresponding direction. The soft robot has two working
modes of quick grabbing and wriggling and
crawling, and the potential application value of the soft robot is expanded.
