Service robot transformable Mecanum wheel movable chassis

Abstract

The invention discloses a service robot transformable Mecanum wheel movable chassis. The chassis is characterized by comprising a Mecanum wheel, a fixed hook, a transformable wheel body, an outer sideouter plate, a hexagon nut, an outer plate bolt bar, a self-tapping screw, an inner side outer plate, a steering engine U-shaped frame, a connecting shaft, a steering engine, a fastening screw, an inner plate connecting bolt, an inner plate connecting nut and an inner plate. The transformable Mecanum wheel of the movable chassis can be opened, a Mecanum wheel roller responsible for all-directionmovement is arranged outside, and the transformable wheel body is arranged inside. According to the transformation principle, when the movable chassis encounters an obstacle, the steering engine controls the inner plate to rotate, a transformable wheel spoke rotates to make an outer plate bolt to slide in a slide way, and the transformable Mecanum wheel is supported and opened to form a three-jawshape. The effective obstacle crossing radius is expanded, and the movement requirements for striding across a threshold are met. Therefore, two original motive parts exist when the movable chassis moves and strikes across the obstacle, a DC servo motor controls the movement, and the steering engine controls the relative rotation of the inner plate and the outer plate and controls deformation.

Description

technical field [0001] The invention belongs to the technical field of omnidirectional movement of service robots, and in particular relates to a deformable wheat wheel movement chassis of a service robot, so as to realize the function of overcoming obstacles while realizing flexible steering. Background technique [0002] With the rapid development of the world economy and the continuous improvement of human living standards, people's consumption objects are increasingly turning to the service direction. Emerging service robots adapt to this trend and are currently booming. Service robots are used in many occasions such as catering services, shopping mall services, conference services, and home public use. However, due to the narrow terrain and heavy flow of people in the application, the chassis performance of the service robot is required to have the ability to pass through a small space, and it also needs to have a certain ability to overcome obstacles when necessary. ...
