Abstract: A method for determining a motion path on a surface in an environment, along which motion path a mobile appliance, in particular a robot, preferably a domestic robot or a robot vacuum cleaner, is intended to move. The method includes obtaining environment information and determining a region of the surface intended to be covered by the motion of the mobile appliance; determining, while taking into account the environment information, whether within the region there is at least one uneven area in the surface that can be negotiated by the mobile appliance; and determining the motion path while taking into account the at least one uneven area, if there is one. A mobile appliance is also described.

Abstract: A ball toss game and method of playing enables multiple players that form two teams to take turns tossing two sets of uniquely colored or patterned balls into two silos positioned at a predetermined distance from each other, and then award points for a final ball thrown into a top position of the silo. Two sets of balls having unique color or patterns are tossed into the receiving opening of silo. As balls are tossed into the silos, a stacked arrangement forms until final ball is tossed into a top position of stacked arrangement. Points are awarded to the team having the final ball in the top position. The silos have a top funnel forming a receiving opening, a bottom base, and a tube extending between top funnel and bottom base. A restriction member block and releases the balls from falling into the bottom base to be retrieved.
