Abstract

The invention discloses a robot with a variable wheelbase and capable of being lifted. The robot comprises a robot platform, driving wheels, driving wheel connecting rods, rear swinging rods, upper swinging motors, upper swinging rods, assisting motors, front swinging connecting rods, steering engines, steering wheels, lower connecting rods, swinging tooth grooves, lower swinging motors, L-shaped steering connecting rods and steering wheel connecting rods. According to the robot disclosed by the invention, the wheelbase can be enlarged, and the gravity center can be reduced, so that the robot can stably passes through a complex road condition, and stability and reliability of quickly passing through a complex road condition of a wheel type robot are improved; through adjusting the wheelbase of the robot and lifting the gravity center, obstacles are safely passed; and in the whole process of changing the wheelbase, two motors are adopted for providing power, so that total weight is reduced, and structure is compact.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a liftable robot with variable wheelbase. Background technique [0002] Wheeled robot is an important branch of the robot family, which has the advantages of fast speed, high efficiency, and low motion noise. It occupies an important position in the field of special robots. At the same time, wheeled mobile robots are also an important research direction for countries to further expand the application field of robots. In order to make wheeled robots adapt to the different requirements of various working environments, various mobile mechanisms have been developed one after another. Therefore vigorously developing wheeled robots has become the research direction of countries all over the world. [0003] Traditional wheeled robots are suitable for flat roads, especially roads. Although they have the advantages of fast moving speed, high efficiency, and low motion noise, they are ...
