Abstract
Home service robot is a special robot for human services, mainly engaged in
home services, maintenance, maintenance, repair, transportation, cleaning, care and
other work, it plays a role in the service of human daily life, but also acts as an
electrical appliance, mobile robot assistant robot, entertainment robot, humanoid
robot's role. With the advent of global aging, the burden of family and society are
increasing, the home service robot plays an increasingly important role, the service
robot industry market continues to expand, the number of sales of various special
service robots are increasing year by year. Wireless communication, path search,
navigation and positioning, machine vision, object recognition, human-computer
interaction, the characters follow constitute the main body of the home service robot,
in wireless communication, combining the use of the network and the robot; using
three universal wheels at a 180 degree angle to control the robot moving direction, so
that the robot can move in any direction move, and do not need to change toward
exercise. In the following figures are used, a method for gait recognition by laser, has
the advantages of high efficiency, rapid and accurate; machine vision, the robot uses
the latest Microsoft Kinect2.0, with a high resolution video, clear image, motion
capture accurate advantages, at the same time in face recognition and object
recognition in the the machine learning method makes the recognition more accurate;
not by the traditional robot using odometer positioning, but through laser data
acquisition for positioning, makes the robot more precise positioning. In the path
