In order to study the influence of deck shaking during ship motion on the stability of ship deck foreign matters cleaning robot, based on the random wave model and the ship's motion with the wave, MATLAB software was used to simulate and analyze the random wave, the ship's motion with the wave and the force of the ship deck foreign matters cleaning robot, and satisfactory simulation results were obtained. In this paper, the stability of ship deck foreign body cleaning robot is analyzed, and a stability analysis method is proposed, which provides a theoretical basis for the stability analysis of ship robot.
Underwater manipulator plays an important role in underwater operation, and structural design is of great significance to the function and underwater operation of underwater manipulator. At present, the structural design lacks systematic summary. This paper attempts to illustrate the structure of underwater manipulator according to its carrier, operation and function, clarify the matters needing attention in the design of underwater manipulator, and provide summary experience for the design of underwater manipulator.
Biology has evolved over hundreds of millions of years to form excellent bionic objects that inspire the design of bionic robotic mechanical structures, and combing bionic structures and objects from an evolutionary perspective can make the design of mechanical mechanisms clear. Arthropods occupy 80% of the animal species, among which spiders, locusts, dragonflies, and butterflies with flying abilities are excellent bionic objects.
Welding technology is the foundation of structure forming process in mechanical industry, and welding seam tracking is the key technology of intelligent welding. The scholars current study of welding seam tracking has been a lot, but mostly involves complex visual identification, complicated control algorithm and multi-sensor data acquisition, brings to the system to deal with the heavy burden of data operation, and in practical production because of the different welding conditions, to have different demands, this paper in all kinds of welding conditions for classification principle. The advantages and disadvantages of various weld tracking methods are summarized, and the tracking methods with adaptability under various working conditions are put forward, which can be used for reference by readers of various research directions.
