Abstract
Description
Technical Field
[0001] This utility model relates to the field of handling robot technology, specifically a chassis structure for a mobile handling robot. Background Technology
[0002] The chassis of a handling robot is a key component, determining its mobility, load capacity, and environmental adaptability. Here are some common chassis types for handling robots: wheeled chassis and dual-wheel differential chassis. Structural principle: Two drive wheels are located on the left and right sides of the chassis, with independent speed control for each wheel. Steering is achieved by setting different speeds. It is typically equipped with one or two auxiliary omnidirectional wheels. Advantages: Simple structure, low cost, good flexibility, can rotate in place, and the ROS-based DWA path planning algorithm is well-suited for it. Disadvantages: Relatively large turning radius, less precise in high-precision steering scenarios, and prone to slippage on smooth surfaces or at high speeds. Application scenarios: Widely used in indoor material handling, warehousing, and logistics scenarios, such as material distribution in factories and goods handling in warehouses.
[0003] Patent publication number "CN216472078U" discloses "A handling robot, relating to the field of intelligent warehousing technology, used to solve the problem that the counterweight of handling robots in related technologies cannot flexibly adjust the center of gravity position of the handling robot. The handling robot provided in this disclosure includes a mobile chassis, a main structure, and a counterweight module. The main structure is disposed above the mobile chassis; the counterweight module is disposed in the horizontal plane of the mobile chassis; the counterweight module includes an adjustment mechanism and a counterweight block, the adjustment mechanism and the counterweight block are connected, and the counterweight block moves in the horizontal plane of the mobile chassis under the drive of the adjustment mechanism.
