Abstract

The invention provides a robot chassis. The robot chassis comprises a chassis main body, a driving assembly, two driven wheels and two driving wheels, wherein the two driven wheels are respectively arranged on the front side and the rear side of the bottom of the chassis main body; the two driving wheels are respectively arranged on the left side and the right side of the bottom of the chassis main body; the driving assembly comprises a hanging body and a power device which is used for driving the driving wheels to rotate; the driving wheels and the power device are fixed on the hanging body;a spring fixing bracket is fixed at the upper part of the chassis main body; and the driving assembly is connected with the spring fixing bracket through a spring. According to the robot chassis, through elastic connections between the driving wheels and the chassis main body, the high stability of a robot is guaranteed; and under an effect of a compression spring, the driving wheels suffer downward pressure so as to guarantee close contacts between the driving wheels and the ground so that the robot can also normally run on the uneven ground. A technical problem that the robot in the relatedtechnology cannot normally run because the driving wheels of the robot are impending in the running process due to the uneven ground is solved.

Description

technical field [0001] The present application relates to the technical field of robots, in particular, to a robot chassis and a robot including the same. Background technique [0002] Now service robots have entered our lives, including welcome robots in shopping malls, security monitoring robots, and household sweeping robots. These robots can walk independently. A part of the existing robot chassis adopts a three-wheel structure, two driving wheels and a follower wheel, and relies on the speed difference between the two driving wheels when turning. This method has a simple structure and good reliability. However, in places like shopping malls where there is a relatively large flow of people, the robot with a three-wheel chassis has poor stability and may fall when encountering external forces. If you live in a place with a compact space like a home, there will be certain restrictions on the space required for the robot to turn. Although the three-wheel structure of the c...
