Abstract

The invention provides an obstacle crossing robot. The obstacle crossing robot comprises a front right-angle leg mechanism, a bottom plate and crawler wheels. Reinforcing ribs are mounted over the bottom plate, and the reinforcing ribs are connected with the bottom plate through bolts; front rotating shaft fixing seats are installed at the two sides of the front end of the bottom plate through bolts. A front rotating shaft is embedded into the front rotating shaft fixing seats, and the front rotating shaft is connected with the front rotating shaft fixing seats through bearings; two ends of the front rotating shaft penetrate through the front rotating shaft fixing seats and are connected with the front right-angle leg mechanism through bolts; and front wheels are mounted on the front right-angle leg mechanism through bolts. According to the invention, the obstacle crossing robot is improved; the robot has the advantages of being reasonable in structural design, simple in movement mode,low in manufacturing cost, capable of meeting the requirements of high-speed and convenience for wheel type robots and stable obstacle crossing performance for crawler type robots, suitable for various complex terrains, high in maneuverability and high in practicability, and therefore the problems and defects existing in an existing device are effectively solved.

Description

technical field [0001] The present invention relates to the technical field of robots, and more specifically, relates to an obstacle-surmounting robot. Background technique [0002] At present, obstacle-crossing robots mainly have structures such as legged, crawler and wheeled structures, each of which has its own advantages and disadvantages: the legged type is convenient for movement, but has a small load; the crawler type has a large contact area, but has a complex structure and high power consumption. ; The wheel type has high efficiency and fast speed, but it is only suitable for flat roads, and it is difficult to realize the obstacle-crossing function for complex roads such as mountainous areas. At present, the obstacle-crossing effect of obstacle-crossing robots on the market is not obvious, and the robots on the market cannot really assist or replace manual work in the process of performing work. [0003] In view of this, the existing problems are studied and improv...
