'''A robotic lawn mower is a lawn mower that is able to mow a lawn by itself after being programmed. Once programmed, this invention repeats the operation by itself according to its programming. Robotic lawn mowers comes with a power unit which may be an electric motor or internal combustion engine. This provides power to the robot and allows it to move itself and its cutting blades. There is also a control unit which helps the mower move itself. This unit also contains a memory unit which records and memorizes its operation programming. Its memorized route includes the length of travel in a given direction and turn angles. This allows the same lawn to be mowed repeatedly without having to reprogram. The steering unit acquires an operation signal and propels the lead wheel, which leads the mower, go guide along the programmed route.'''

'''Window cleaning robots are most commonly used to clean outdoor windows, more specifically house windows. However, it may be used on other types of windows, such as ones on tall buildings and structures. This robot contains a movement system which allows the robot to navigate itself across the window surface in a defined direction. It also has a powered agitator located by the cleaning pad. When activated, the agitator gets rid of debris and dirt from the window surface. The cleaning pad directly interacts with the window surface and is directly responsible for removing the dirt by filling itself with specialized window cleaning fluid.'''
