In order to solve the problem of dining of the elderly or the upper body amputation

a design scheme of feeding assisted manipulator based on machine vision is proposed

and uses the D-H method for modelling of manipulator

and simulation verification on the results of forward and inverse kinematics analysis of the manipulator is carried out. At the same time

combined with PID algorithm based on face tracking research and analysis are carried out

and then the visual PID face tracking algorithm is verified by experiment. Finally

in order to enhance the sense of human-computer interaction

speech recognition technology is also used to further improve the auxiliary feeding system of the auxiliary feeding robot

which effectively improves the human-computer interaction experience.
