This project focuses on the handling of explosives in hazardous situations. It is mainly composed of walking mechanism, telescopic table, rotary table, detection platform, water knife, liquid nitrogen storage tank, liquid nitrogen delivery pump, jet trailer, jet water pump and other parts. Starting from the shortcomings of the existing EOD robots, the work innovatively designs a multi-water knife EOD robot based on liquid nitrogen cooling, which cuts explosives through water jets to prevent explosions, and uses liquid nitrogen cooling to further ensure the safety of the EOD process. In addition, this product uses a double water knife structure, through the use of mechanical arm, rotating table, telescopic table and other devices so that the water knife has multiple degrees of freedom, can effectively meet the destruction of explosives under different positions and posture tasks, a wide range of applications. This product uses pan-tilt to adjust the position and angle of the camera while cutting, and monitors the cutting position in real time to ensure the cutting accuracy and the safety of EOD.
