Problems solved by technology

[0003] Traditional crawler robots have two degrees of freedom or three degrees of freedom, that is, there are only two main motion modules or two main motion modules plus a pair of swing arms that move simultaneously, which simplifies the design difficulty, but reveals some in terms of maneuverability. Insufficient, manifested as limited obstacle height, unstable movement when going downstairs, etc.; the crawler mechanism of traditional crawler robots is mostly separated from the main body of the robot, which facilitates the design of the main body of the robot, but the insufficiently compact design makes the grounding area insufficient, affecting its Mobility performance in non-structural environments; traditional crawler robots mostly use gears or chain drives, which cause problems of increased weight and unstable transmission; traditional crawler robots are mostly directly connected to the frame for control, power and other components, which is not conducive to The protection of important components also brings inconvenience to installation and commissioning

Abstract

The invention relates to a crawler type six-freedom-degree mobile robot which comprises a frame, main motion modules, swing arm motion modules, a control box and sensors. The whole robot has six freedom degrees, two main crawlers can move independently, through the design of a crawler type structure, the robot has high ground passage capacity and can run, steer and the like on a complex road surface, four swing arms can also move independently, and therefore the robot has excellent performance on climbing stairs, crossing obstacles and obstacle avoidance and other tasks.

Description

technical field [0001] The invention belongs to the technical field of ground mobile robots, and in particular relates to a crawler-type six-degree-of-freedom mobile robot with high maneuverability, which can cope with complex terrains, such as steps and stairs inside buildings, environments with obstacles, and building collapses The robot can be used in disaster site surveys, search and rescue tasks, and provide important first-hand information for search and rescue personnel. Background technique [0002] Natural disasters and man-made disasters have always been daunting because of their huge destructiveness, and post-disaster investigation and search and rescue work are particularly important, but often after a major disaster occurs, the site environment is too complex and has many unknown dangers, such as nuclear Radiation, chemical substance leakage, biochemical pollution, high temperature, high humidity, secondary collapse of dilapidated buildings, etc., are beyond the...
