[0002] With the advancement of technology and the increasing cost of labor, companies are actively promoting industrial robots. However, during the use of industrial robots, it was found that the traditional method of fixing the robot to a single workstation to operate can only adapt to the production of a single product. If the order volume of the product is small or the order volume of a product with a large order volume decreases, the robot will be idle. Therefore, existing manufacturers will install a base on the industrial robot that can be flexibly controlled and moved. However, the mobile base usually uses rollers for movement. When the robot is located on a certain slope or smooth ground, although the rollers can be self-locking, the inertia generated by the robot's mechanical wall when rotating when carrying heavy objects will cause the rollers to move slightly, resulting in the robot not being able to stay stable in the designated location. Over time, it will slip. Therefore, a positioning device for mobile handling robots is needed. Utility Model Content
