A polyurethane resin composition includes a reaction product of an aliphatic polyisocyanate derivative having an average number of isocyanate groups of 2 or more; a long-chain active hydrogen compound including a hydrocarbon group having 12 or more and 30 or less carbon atoms and an active hydrogen group in combination; a cationic active hydrogen compound including an active hydrogen group and a cationic group in combination; and an acid compound capable of a salt with the cationic group. The concentration of the hydrocarbon group is 30% or more and 85% or less.

In mobile robot that runs from first flat surface which is a magnetic body to second flat surface which is a magnetic body and intersects the first flat surface, the mobile robot includes a pair of driving wheels which is rotatably supported to robot body and includes permanent magnets on outer circumferential surfaces thereof; driving mechanism which drives the pair of driving wheels to be independently rotated; rear wheel which is rotatably supported to the robot body and includes permanent magnets on an outer circumferential surface thereof; distance sensor which acquires a distance to the second flat surface; and pressing out mechanisms which include pressing out members which are movable between contact position at which the pressing out member can be in contact with the first flat surface and retracted position at which the pressing out member is retracted from the first flat surface. The pressing out member is moved from the retracted position to the contact position to be in contact with the first flat surface by the pressing out mechanism, the driving wheels is separated from the first flat surface, and the driving wheels move from the first flat surface to the second flat surface, when the distance sensor detects that the driving wheels are in contact with the second flat surface.
