WINDOW CLEANING ROBOT

摘要

PURPOSE: A window cleaning robot is automatically move a robot part by making friction drive using magnetic attraction between drive wheels. CONSTITUTION: A window cleaning robot comprises a first robot part(10) and a second robot part. The first robot part comprises a first body plate(11), a first wiper, a first friction drive wheel(21), and a wheel driving motor(23). The first friction drive wheel moves the first body plate using the reaction force by frictional force with the surface of a window. The wheel driving motor generates the power rotating the first friction drive wheel. The second robot part comprises a second body plate and a second friction drive wheel. The second friction drive wheel is contacted with the surface of a window and rotates in order to move a second main body plate. A magnet is installed at one of the first friction drive wheel and the second friction drive wheel in order to generate normal force which is used for friction drive.
