The invention provides a multifunctional household
service robot which uses a crawler-type running
system. The multifunctional household
service robot comprises a
maintenance system and a clear-up
system; the
maintenance system comprises a maintenance table and a butt-joint lamp group; the maintenance table mainly consists of a maintenance table lifting mechanism, a maintenance table push arm transmission mechanism, a maintenance table push arm cleaning mechanism, a charging joint, a positioning detection light
sensation triode, a shooting indication lamp and the like; main mechanisms of the clear-up
system are distributed in a
chassis rack, and comprise a push arm, an ejector door and a lifting table from top to down in sequence; the push arm consists of two moving pairs; the ejecting door comprises an ejecting door right face and an ejecting door left face, which are connected through a connecting rod of a
crank sliding block, and are driven by transmission mechanisms which are symmetrically arranged at the top of the
chassis rack; and the lifting table consists of a platform and four screw rod nut mechanisms for supporting the platform. According to the multifunctional household
service robot provided by the invention, the basic moving technology of the household service
robot, such as simple indoor positioning and path planning can be realized, so that the multifunctional household service
robot has
actual use values when mission is carried out indoors; the full-automatic services can be basically realized; and the inconvenience brought by
remote control can be avoided.
