Abstract

The invention provides a cuttlefish-imitating robot based on two-way SMA spring driving, and belongs to the field of bionic robots. The problems that a traditional driver represented by a motor is large in noise, low in driving efficiency and the like are solved. A power part, a control part, a transmission part and an execution part of the robot are sequentially connected, the left end of a sliding rod of the execution part is connected with the right end of a rear end cover, the right end of the sliding rod is matched with the left end of a sliding groove, and relative sliding can be generated; the right end of the sliding groove is connected with the left end of the front end cover. The left end of the two-way SMA spring is connected with the sliding rod, the right end of the two-way SMA spring is connected with the sliding groove, and the transmission part is connected with the two-way SMA spring and supplies power to the two-way SMA spring. The shape memory alloy is used as a driver, the cuttlefish-imitating robot based on double-stroke SMA spring driving is designed, the cuttlefish-imitating robot is driven by the double-stroke SMA spring, a sliding rod and sliding groove device is used as an executing mechanism, and efficient and high-speed advancing can be achieved underwater.

Description

technical field [0001] The invention belongs to the field of bionic robots, in particular to a squid-like robot driven by a double-way SMA spring. Background technique [0002] Many researchers are developing new tools for underwater missions due to increased demands related to ocean engineering such as cables, pipelines, natural gas drilling and seafloor surveying. Due to its high environmental adaptability, good compliance and high maneuverability, the bionic underwater robot has once become a research hotspot of underwater robots. However, the traditional drive represented by the motor has defects such as high noise and low drive efficiency. Contents of the invention [0003] In view of this, the present invention aims to propose a squid-like robot driven by a double-way SMA spring to solve the problems of high noise and low drive efficiency in the traditional drive represented by a motor. [0004] To achieve the above object, the present invention adopts the followin...
