A composite climb structure includes a climber, a horizontal planar structure, and a ramp coupled on to a base plate. The horizontal planar structure and the ramp are collinearly situated on opposite sides of the climber. The climber is pressed by a robotic vehicle moving on to it from the horizontal planar structure, the climber being pressed to a final position, wherein the angle of elevation (BOC) of the climber is same as the angle of elevation of the ramp, thereby facilitating traversal of the robotic vehicle from the horizontal planar structure on to the ramp.
