Abstract
The current wheel type or crawler type robot has various problems when used; for example, when a wheel type robot is adopted, the wheel type robot can quickly move in environment, but the wheel type robot can not run on bumpy road surfaces, or muddy road surfaces, or spongy road surfaces; a crawler type robot overcomes the problem that the wheel type robot is easy to immerse the muddy and the spongy road surfaces when runs, etc., but the crawler type robot has the problems of low running speed, easy abrasion, etc. The robot of the present invention has a basic function of an ordinary obstacle surmounting robot and integrally utilizes a wheel type and a crawler movement drive types; because the structure is changed, the robot is suitable for various different road conditions, such as flat road surfaces, bumpy road surfaces, muddy road surfaces, spongy road surfaces, certain gradient, etc.; the present invention fully utilizes the advantage that the wheel type mechanism can quickly run on the flat road surfaces and fully utilizes the advantage that the crawler type mechanism has strong adhesion force of road surfaces in small unit area on other road surface conditions; thereby, the present invention can favourably pass. When the present invention runs on road surfaces and encounters an obstacle which is a ravine or a bump, the present invention has reinforced special functions that the contact length, the gravity center and the pose of the robot and the ground are regulated through a continuous combined structure deformation, which causes that the robot can reliably pass the obstacle without causing that the robot is blocked or immersed; when the obstacle is a ravine, and the width of the ravine is less than the sum of 1/2 crawler length and an arm length; or when the obstacle is a bump, the height of the bump is lower than the sum of a wheel diameter and the arm length.
Description
Technical field
The present invention is a kind of adopt composite structure, robot device with structural distortion ability.Robot is placed various structurings or open-air uncertainty environment, can carry out normally moving, can cross the obstacle of projection, and can be by the gully of certain width.
Background technology
There is variety of issue in existing wheeled or caterpillar type robot in application.Such as, adopt wheeled robot, though can quick travel in environment, can not adapt to rugged, muddy and soft road traveling; Problems such as and caterpillar type robot though overcome problem such as being absorbed in of easily running into when wheeled robot travels on muddy and soft surface, exists moving velocity slow, and is easy to wear.
This robot device's meaning is: the basic function with common barrier-surpassing robot, integrated use therein is wheeled, two kinds of motion drive forms of crawler belt, and by structural distortion, make robot adapt to various condition of road surface, such as, smooth, rugged, muddy, soft, and certain gradient etc., on smooth road surface, make full use of the advantage that wheeled mechanism can fast running, and under other road conditions conditions, the unit area that then makes full use of crawler belt is stressed little, the advantage that road adherence is big makes and can pass through smoothly.The unique function of the enhancing that this robot has is, in the road traveling process, run into obstacle: one, obstacle is the gully, the gully width adds upperarm length less than 1/2 track length, and two, obstacle is protrusion, obstacle height is lower than the wheel footpath and adds upperarm length, by continuous unitized construction distortion, adjust robot and ground-surface length of contact, center of gravity and attitude, make robot reliably to break the barriers, can not cause robot to be blocked or to be absorbed in.
Summary of the invention
