Top end object placing table and mobile robot trolley with same

Abstract

The invention discloses a top end object placing table and discloses a mobile robot trolley with the top end object placing table, and the top end object placing table comprises a base plate, a fixing cover, an anti-twisting assembly and an object carrying assembly. The substrate is provided with a convex ring; the fixing cover is arranged on the substrate and sleeves the outer side of the convex ring; an opening is formed in the top end of the fixing cover; the anti-twisting assembly is rotatably arranged in the fixing cover and is positioned above the substrate; the object carrying assembly is arranged at the upper end of the fixing cover and located above the anti-twisting assembly, the anti-twisting assembly can abut against the object carrying assembly, the object carrying assembly comprises an object placing plate, and the object placing plate can move. And the movable object placing plate can passively conform to the pose change of the object on the movable object placing plate, so that the movable object placing plate can be attached to the surface of the object, and the risk that the object falls off is reduced. And the anti-twisting assembly can abut against the object carrying assembly, so that the object carrying assembly is prevented from generating torque internal stress in the vertical direction due to rotation of the object carrying assembly, and finally the situation that the motion direction of the robot is interfered and changed can be avoided.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a top storage platform and a mobile robot trolley provided therewith. Background technique [0002] Mobile robot carts are increasingly used in factories and warehouses for the transportation of goods. For larger goods, multiple mobile robot cars can coordinate and support the goods to complete the handling. In the process of transporting goods in this way of "ants moving", a firm contact between the goods and the robot needs to be maintained, otherwise the goods will have the risk of slipping. However, there may be sudden changes in the terrain during transportation, such as bumps on the ground, which may cause a certain part of the robot to change its height or tilt, and the relative pose between the object and the robot will also change. If the top shelf of the robot cannot adapt to change its posture, then the contact between the robot and the object will become a relatively...

Problems solved by technology

However, there may be sudden changes in the terrain during transportation, such as bumps on the ground, which may cause a certain part of the robot to change its height or tilt, and the relative pose between the object and the robot will also change.

If the top shelf of the robot cannot adapt to change its posture, then the contact between the robot and the object will become a relatively weak point-surface contact or line-surface contact, and the object is at risk of falling

[0003] In addition, when swarm robots cooperate to carry objects, due to the error in control accuracy, there is often a torque internal stress in the vertical direction between the robot and the object. If this stress cannot be eliminated in time, it will slowly change over time. The movement direction of the robot affects the completion of the coordinated handling task of the swarm robots
