Method and system for self-adaptive adjustment of mechanical claw grip force of claw machine

Abstract

The invention provides a method and system for self-adaptive adjustment of gripping force of a mechanical claw of a fun catcher. The method comprises the steps that (S1) an object is placed under the mechanical claw of the fun catcher, a high initial drive voltage is provided to an electric motor by a drive circuit of the mechanical claw, and the mechanical claw is made to grasp the object; (S2) drive voltages output by the drive circuit of the mechanical claw are reduced continuously till the object falls from the mechanical claw; (S3) at the instant of object falling, the drive voltage output by the drive circuit of the mechanical claw is recorded; and (S4) the drive voltage recoded at the step (S3) is set as a constant output voltage of the drive circuit of the mechanical claw. According to the invention, the drive voltage of the mechanical claw is adjusted and checked by a software program in real time; the gripping force of the mechanical claw is adjusted automatically by the program; and the optimal force is obtained automatically through adjustment. The method and the system provided by the invention have the advantages that the previous problem that manual adjustment must be conducted according to experience is solved; accuracy and stability of gripping force adjustment are enhanced; and working efficiency is increased.

Description

technical field [0001] The invention relates to the field of amusement equipment, in particular to a method and system for self-adaptive adjustment of the gripping force of mechanical claws of a claw machine. Background technique [0002] Before the claw machine is put into use, it is necessary to properly adjust the grasping force of the mechanical claws. It is necessary to avoid too low grasping difficulty caused by excessive grasping force, and to avoid too large grasping difficulty caused by too small grasping force. [0003] However, the grasping force of the mechanical claws of different claw machines on items will be affected by the following factors: the hardware equipment used in the claw machine, such as the shape, size and manufacturing process of cranes, motors, mechanical claws, etc.; The newness and oldness of use; the size, material, weight and oldness of the items grabbed by the claw machine. All the above factors will affect the grip adjustment scheme of t...
