Abstract

The invention discloses a four-wheel independent-drive mobile robot with an anti-shock function. The mobile robot comprises a controller, a chassis and at least four wheel assemblies mounted on the chassis. The chassis is used for bearing to-be-transported goods or mounting other apparatuses. Each wheel assembly comprises a wheel, a support, a drive motor, a hydraulic cylinder and a steering motor, wherein the drive motor and the wheel are mounted on the support, the drive motor drives the wheel to rotate, the support is mounted under the chassis through the hydraulic cylinder, and the steering motor is mounted on the chassis and can drive the support to rotate around the central axis of the hydraulic cylinder. The controller controls the drive motors, the steering motors and hydraulic pumps of the hydraulic cylinders. According to the mobile robot, each wheel is driven by the special motor to rotate and steer, so that moving of the mobile robot is more flexible, the controller controls the mobile robot more precisely, and the application occasion of the mobile robot is expanded.

Description

technical field [0001] The invention relates to the field of logistics equipment, in particular to a four-wheel independently driven mobile robot with shockproof function. Background technique [0002] Mobile robots refer to wheeled robots with autonomous motion control and path planning, which are widely used in logistics, warehousing, catering services, line inspections and other fields. Mobile robots mainly move within a set range (usually indoors) according to set procedures and trajectories to provide transportation or other related services. Most of the current mobile robots are four-wheel robots, which have the following two disadvantages in the working process: (1) The motion control of mobile robots is mostly based on differential speed, including two-wheel differential and four-wheel differential robots, two-wheel differential The steering of mobile robots is not sensitive enough, and the application conditions are greatly affected by site factors; the wheels of f...
