Wall-climbing robot

The invention relates to a wall-climbing robot. The wall-climbing robot comprises a robot main body, a walking structure and a plurality of groups of magnetic attraction structures, the walking structure comprises a walking part and a driving part which are arranged on the robot body, the walking part is movably arranged relative to the wall surface so that the robot body can move on the wall surface, and the driving part is in driving connection with the walking part; each group of magnetic attraction structures comprises working electromagnets, the working electromagnets are detachably mounted on the walking part, are used for being attracted to the wall surface when being powered on and can be separated from the wall surface when being powered off, and the multiple working electromagnets are arranged at intervals, so that at least part of the working electromagnets can be magnetically attracted to the wall surface when the walking part moves. According to the scheme, by means of the magnetic force of the w
