Abstract
The present invention comprises a novel stair climbing device for self-moving robots that allows moving between dwelling levels using existing straight as well curved stairs. The straight ramp is attached to the stair's wall in a folded state and placed on the stair in the unfolded state. The curved ramp is stored in a folded state and is placed in the stair in unfolded state. When a vacuum robot comes close to the ramp, it can be unfolded automatically or manually and allows the robot to go up or downstairs to the next level of the dwelling. When the ramp is not in use, it can be folded into a stored state or/and be removed. The stairclimbing aide's dovetail ramp allows a robot to climb on the ramp due to its lower approach angle.
