Problems solved by technology

In an open workplace, it is impossible to plan the handling path according to the location of the goods, and automatically complete the loading and unloading of the goods
[0004] The robotic arm is the most important and core component of the robot. Most of the robotic arms currently on the market are joint-type, and the movement of the robotic arm is driven by the movement of the joint. The requirements for the drive motor inside the joint are relatively high, and the motor power is large. At the same time, it also greatly increases the weight of the robot, making it difficult to move.
Therefore, it is very difficult to design an articulated robot as a mobile robot that can move flexibly

Abstract

The invention discloses a mobile robot composed of a mobile lifting column, a mechanism type telescopic arm and a control system, which can walk freely on the ground and plan a transport path according to the starting position and the ending position of a target object. Compared with the fixed palletizing robot, the mobile robot of the present invention can realize multi-position palletizing and handling of target items, and the application scene is more flexible. The invention adopts the in-situ rotation of the mobile lifting column to replace the turntable structure of the fixed palletizing robot, and uses the mechanism-type telescopic arm to replace the joint-type swing arm and the track-type moving arm, so that the structure of the whole machine is simpler and the power-to-quality ratio is higher. The overall power consumption and overall weight of the machine are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a mobile robot. Background technique [0002] The advancement of modern technology and industrial technology has enabled robots to show strong vitality in various industries. The breadth of robot applications in society and the depth of its own technical research have become a measure of a country's industrial intelligence level. Robots are the product of the organic combination of machinery and computer programs, which provide higher production efficiency for modern production. Machines are widely used in industries, which can greatly save labor and improve work efficiency. [0003] At present, the working position of the robot capable of handling heavy items (such as more than 100kg) is fixed, and it is usually fixed next to the production line to perform assembly or handling operations on the objects on the assembly line. In an open workplace, it is impossible to plan the hand...
