EOD robot

Abstract

The invention discloses an EOD (Explosive Ordnance Disposal) robot. The EOD robot comprises a chassis, a searching mechanism and a grabbing mechanism, wherein the searching mechanism and the grabbing mechanism are arranged on the chassis; the chassis comprises a first platform, a middle platform and a second platform which are connected in sequence, two ends of the middle platform are respectively hinged to the first platform and the second platform, lifting mechanisms are respectively arranged between the middle platform and the first platform as well as the middle platform and the second platform, the first platform, the middle platform and the second platform are respectively provided with a pair of crawler wheel traveling mechanisms and two DC (Direct Current) speed reduction motors; the searching mechanism and the grabbing mechanism are arranged on a same rotating frame, the lower part of the rotating frame is connected with the middle platform through a rotating shaft, the grabbing mechanism comprises a robotic arm and a gripper, one end of the robotic arm is connected with the rotating frame, and the other end of the robotic arm is connected with the gripper through a first steering engine; the searching mechanism comprises a camera, a first support and a second support, the rear end of the first support is connected with the rotating frame, the front end of the first support is connected with the second support through a third steering engine, and the camera is arranged on the second support through a fourth steering engine.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an anti-terrorism anti-explosive robot. Background technique [0002] With the increasingly severe global anti-terrorism situation and frequent terrorist attacks at home and abroad, the armed forces and security departments of various countries have a huge demand for EOD robots. At present, the cost of EOD robots launched in domestic and foreign markets is relatively high, which is not conducive to large-scale promotion. [0003] EOD robots belong to the category of ground mobile robots in unstructured environments, and the research on it abroad started earlier. European and American capitalist countries such as the United Kingdom, France, Germany, and the United States have successively launched technical research on EOD robots. Most of the earliest EOD robots were used for military purposes. With the development of the times, many products have been used for civilian use, and...

AI Technical Summary

Problems solved by technology

[0006] 1. In order to install a large amount of equipment, the EOD robot makes the structure complex and bulky

EOD robots can't perform well or can't complete the task in a special environment with a small space

[0007] 2. The cost of EOD robots is too high, and the price of low-end products is more than 200,000 RMB. Due to the high cost, it cannot be equipped in large quantities, resulting in a large number of manual EOD robots, which increases the danger of EOD workers.

[0008] 3. The EOD robot generally adopts a tank-type chassis, but since the EOD robot must work under harsh road conditions, the ability to overcome and avoid obstacles must be strong, so it uses crawler wheels, but only has one or two sections of the chassis , when passing through larger obstacles, it is usually impossible to cross obstacles that are about the same height as itself. At the same time, during the uphill or downhill process, the EOD robot chassis is less prone to imbalance

[0009] Existing EOD robots usually have a robot body with a manipulator structure, and can only remove suspicious objects when performing tasks. In some special cases, the danger cannot be eliminated immediately, and even unnecessary casualties will be increased. The manipulators of these EOD robots usually adopt a two-section arm structure, and the flexibility and extension distance of the manipulator still need to be improved. In actual use, it is often impossible to perform special grasping postures in narrow positions.

[0010] The shortcomings of the EOD robot hardware system can be summarized as follows: huge size, high cost, scattered hardware structure, unbalanced layout, poor flexibility of the mechanical arm, insufficient stretching distance, poor climbing, downhill and obstacle-crossing capabilities.
