Description

technical field [0001] The present invention relates to the fields of space operation, surgical operation robot and flexible manufacturing, and more specifically relates to a shape memory alloy soft driver. Background technique [0002] In recent years, the application of robots is no longer limited to the traditional manufacturing field, but has gradually expanded to medical rehabilitation, resource detection, national defense and military fields. In these fields, the working environment and task requirements have become complicated. Traditional rigid robots have shortcomings such as limited flexibility, poor biocompatibility and environmental adaptability, making it difficult to adapt to the working environment and complete task requirements. In response to this problem, people have developed a variety of soft robots by imitating soft organisms such as octopuses and earthworms. These soft robots have high structural compliance and good environmental adaptability, and have...
