Problems solved by technology

At present, in terms of mechanical structure and control of chewing robots, a single indenter is used to replace the jaw compression mechanism or a typical Stewart platform and its deformation mechanism driven by an electric cylinder, a servo motor, and a motion control card. Anti-interpretation and control are more complicated, and the organization is also relatively large

Abstract

The invention relates to the technical field of robots, particularly to a bionic masticatory robot for denture and food detection. The bionic masticatory robot consists of: an XY work platform, a mandibular mobile platform, a maxilary platform, a temporomandibular connecting piece, a drive control system, and two drive chains. The two drive chains are symmetrically arranged on both sides of the mandibular mobile platform, the mandibular mobile platform is connected above the XY work platform through a connecting rod, the temporomandibular connecting piece is connected to the mandibular mobile platform and the maxilary platform, the mandibular mobile platform and the maxilary platform are equipped with a denture model, the drive control system controls the driving chains to realize sagittal plane movement of the mandibular mobile platform and controls the XY work platform to realize horizontal plane movement of the mandibular mobile platform. The structure of the invention adopts the XY work platform to cooperate with left and right steering engines to work simultaneously, simulates the chewing movement locus of the horizontal plane and the sagittal plane, overcomes parallel mechanism, inverse kinematics, complex control, and enormous mechanism problems, and has the advantages of simple structure and simple control operation.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a bionic chewing robot used for denture and food detection. Background technique [0002] The chewing robot reproduces the actions of real humans chewing food, and collects and analyzes various information about the chewing process, including different postures of the mandible, joint displacement, and chewing speed. Provide experimental analysis basis for analyzing the chewing characteristics of food materials and dental material testing. Chewing robot research is an engineering science that includes mechanism, mechanical kinematics and dynamics, control engineering, food science, biomechanics and mechatronics. At present, in terms of mechanical structure and control of chewing robots, a single indenter is used to replace the mandibular compression mechanism for chewing movement, or it is driven by an electric cylinder, a servo motor, and a typical Stewart platform and its deform...
