Multifunctional universal robot chassis

Abstract

The invention discloses a multifunctional universal robot chassis, which adopts a wheel type and crawler type combined robot chassis structure that integrates the advantages of a wheel type structureand a crawler type structure and overcomes the defects of the two structures; when the robot chassis needs to rapidly travel, a crawler mechanism is controlled to be folded, and wheels are landed, sothat rapid movement is realized; when the robot chassis needs to climb stairs or cross obstacles, the crawler mechanisms are put down through control, the crawler mechanisms are driven by the wheels to move together, so the stair climbing and obstacle crossing functions are achieved. Compared with an existing composite robot chassis, the multifunctional universal robot chassis is small in appearance sizes, capable of riding an elevator and entering and exiting indoor / outdoor doors, is relatively simple in structure, complete in function, high in universality and wide in application range.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a multifunctional universal robot chassis. Background technique [0002] At present, the robot chassis mainly has three structural types: the wheel structure has the advantages of simple and flexible, fast speed, good stability, and low energy consumption, but it can adapt to less terrain, has limited ability to overcome obstacles, and cannot climb stairs; the crawler structure is suitable for terrain adaptation. The ability is relatively strong, and the performance of climbing and surmounting obstacles is better than that of other structural forms of climbing and surmounting obstacles. It is not easy to slip during the movement, and the traction and adhesion performance is good. During the process of climbing and surmounting obstacles, it can ensure that the trajectory of the robot's center of gravity is always parallel to the connection line of the stairs, with almost no or very...

Problems solved by technology

However, the site of this structure is relatively bulky, large in size, relatively poor in movement flexibility, low in speed, and high in energy consumption; the composite structure can realize functions such as climbing stairs and overcoming obstacles, but the structure is complex, the control system is complex, and the size is large. , Self-heavy, large energy consumption

[0003] Existing robot chassis can only be used for a certain type of robot, and cannot be used in different road conditions, different weather conditions, and different application scenarios, and the versatility is poor
