Abstract:
1. A robot for transforming a rotation movement into a vertical/horizontal displacement on the ground using legs, said robot comprising: a chassis; a rotation shaft connected to said chassis; a plurality of leg modules connected to said shaft at a first end for rotating around said shaft; a plurality of legs, each of said legs being rotatably attached to one of said leg modules at a second end opposite the first end; a mechanism for keeping a lower surface of said legs horizontal to the ground as the robots rotates around the rotation shaft for allowing the robot to move on flat surfaces as well to climb stairs; wherein the leg is connected to the leg module using an arm and the mechanism is a gearing mechanism for controlling the rotation of the leg around the arm at a speed and orientation that allow the lower surface of the leg to remain parallel to the ground as the leg rotates.
