Aiming to solve the current shortage of manual control methods of EOD robots, a 3d coordinate calculation method of EOD robots based on computer binocular vision was studied and developed, and a corresponding control system was designed accordingly to achieve the automatic grasping of EOD robots. This paper first introduces the mechanical structure design of EOD robots, then introduces the principles of computer binocular vision and its software and hardware. Finally, the experiment and analysis of grasping precision are carried out. In grasping, when the hand claw is in front of the robot, the error is minimized. Conversely, when the claw is above or below, to the left or to the right of the front of the robot, the error becomes larger. Meanwhile, the closer the target position, the lower the error. But the visual range of the robot is not very close, otherwise the target may not be caught, or the target may not be able to be in the visual range of the camera.
