The invention discloses a solar-powered diving bionic observation and weeding imitation crab robot, which comprises a main body, crab claws, crab legs and a mimetic waterproof casing. The crab legs and the crab claws are respectively arranged on both sides of the main body. Crab claws comprise a third tong arm fixed on both sides of the front part of the main body, a second tong arm hinged at the end of the third tong arm, and a first tong arm hinged at the end of the second tong arm , the end of the first pincer arm is provided with crab claw weeding shears, and the inside of the crab claw is provided with a shear extension mechanism and a reset mechanism, and the shear extension mechanism is used to drive the crab claw weeding shears to open and merge at the same time. The crab claws are extended inwardly, and the reset mechanism is used to restore the crab claws to their original positions. The invention ensures the least disturbance to the crabs, avoids the influence on the growth and reproduction of the crabs, and timely removes the aquatic plants that grow too fast through the weeding shears of the crab pincers, thereby ensuring that the breeding environment is suitable for the growth and reproduction of the crabs.

The invention discloses an elastic passive folding torsion wing, which comprises a main wing and an aileron, the aileron is elastically connected to the main wing, and the flapping action of the aileron lags behind that of the main wing when it moves; in the flapping motion , the main wing and the aileron are deformed to change the angle of attack of the wing, thereby realizing the passive twisting of the wing during flapping. The present invention realizes the cooperative movement of "swapping-folding-twisting" without increasing the complexity of the mechanical mechanism and the control system by controlling the single degree of freedom "swapping", which effectively improves the aerodynamic efficiency and makes the aircraft more bionic. Close to the flight of real birds.

The invention relates to a random coupling and multi-load laying method for autonomous underwater vehicles. The random coupling and multi-load laying method has the advantages that single adjacent random coupling is introduced in order to overcome the shortcoming of requirements on simultaneously establishing complicated coupling relations between an AUV (autonomous underwater vehicle) and all peripheral neighbors in movement procedures of existing methods; each AUV only needs to establish a coupling relation with a single neighbor in a movement procedure, and the multiple AUVs can cooperatively move by the aid of time-variant target switching on the basis of movement states of the neighbors; the difficulty in implementing cooperation between the AUVs can be simplified, and the integral safety and sailing precision of AUV systems can be improved; AUV movement cooperation procedures can be simplified, cooperation targets can be switched over by each individual in real time according to the movement states of the neighbors, and accordingly the movement flexibility of the systems can be improved while cooperative computation burden is relieved.

The invention provides a multi-robot collaborative motion control method, which uses a two-dimensional grid graph to represent the robot work area, decomposes the work area into blocks, and uses a collaborative control algorithm and a real-time heuristic algorithm to enable each robot to find the total cost Less, meet the total CTL and can move to the next position of the target position, avoid static obstacles in real time, and reach the target position through coordinated movement. The present invention does not need a solver to solve the problem, and considers the solution of the simplified problem from the perspective of the grid method and CTL and LTL. The grid-based map representation method divides the entire environment into several grids of the same size. There is no need to know the global environment information in advance, and each robot can only perceive the environment information within the sensor range and communicate with the robot within the communication range. It overcomes the defects that the centralized control easily leads to the lack of robustness and scalability of the system, and realizes the coordinated movement of multiple robots.
