<p>Water driven robots are provided which can be used for moving different objects at different controlled directions and frequencies to obtain energy and power from the flow of a liquid, such as water. A container (101) contains a siphonic outlet which is capable of converting relatively low continuous flow of water, entering through its inlet (17), to a relatively high intermittent pulsating flow of water, ejected from its outlet (23). Such flow is used for moving the robot as follows: during each cycle, water fills the container so that its weight increases, causing the container to move a pulley (65) or other object (73). When the container's liquid level reaches the inlet of the siphon, it rapidly drains and becomes lighter, thereby resulting in a return of the weight. Thus a continuous inflow of liquid causes the container to oscillate vertically and provides force, energy, and power for operating such robots, for controlling their motion, and for operating work loads connected to the robots.</p> |
