A robotic generator that produces electric power and is actuated by the forces of gravity, the Archimedes principle and Faraday's laws of electromagnetic induction.This robotic generator is an ecological automated robot that can be used as a standalone electric power producing machine, the robotic generator can be small in size to supply electric power to a small building or a single family household, or this robotic generator can be made as large size units and can be assembled in multiple large units working together to produce large amounts of electricity.The robot is contained in two boxes, one box is the motive force sealed in a container full of fluids and the second box contains the generator, the gear box, the electronic controls, pneumatic pump, inverter, battery charger and the energy storage in the form of batteries and or fast charging and fast release capacitor bank.The box full of fluids contains the motive force, these devices are the following; gravity chamber, the Archimedes air bag assembly, the mechanical slide and the assembly that guides the gravity assembly and the Archimedes air bag that travels up and down and the mechanical motion assembly that transforms the linear travel force into rotational torque or force as well as the electromagnetic stop assemblies and the shock absorber control devices, sensors hoses and wiring.All these devices work together to provide the force to move and power the shaft rotation to power the gear box which provides the rotational speed to the shaft of the generator with the rotational speed and power to allow Faraday's law of electromagnetic induction to work since the generator has a long coiled wire assembly on its shaft surrounded by north pole and south pole magnets, when the shaft and rotor is turning rapidly the shaft inside the generator turns and electric current is converting the mechanical, moving energy into electrical energy, this electricity can be used directly by electric appliances, lighting and other electrical needs and the excess electricity can be sent to the electric grid or it can be stored into batteries or capacitor banks located at the base of the robot.This robotic gravity generator can resolve many of the current environmental problems the world is facing. Since this it does not produce any green gasses and can eliminate the power grid problems utilities have since power outages due to down power lines due to storms or hurricanes or other weather related problems can be reduced if not eliminated. This robotic gravity generator is a self sufficient stand alone electric producing apparatus.

An automatic monitoring system for thermal energy storage (TES) plants wherein a pilot ice tank (11) uses Archimedes' principle to determine the ice inventory level by measuring the resultant force (28) of the algebraic addition of the weight of the ice and the reaction of the water pushing the ice up with a force equal to the weight on the water displaced by the volume of the ice. The resultant force (28) applied on a pivoting arm (37) is transferred to a liquid filled bellow (19) and is transformed into hydraulic pressure. The instantaneous hydraulic pressure is transferred to a pressure transducer (21) which converts the hydraulic pressure into an electric current. The electric current is then sent as an electronic analog input to the central control panel (30) of the TES for analysis or display.

The invention discloses a device for measuring the free swelling rate and the water content of a rock and a using method thereof. By adoption of the Archimedes principle as a reference, the device utilizes a basic principle that the volume of displaced water of the rock changes with the volume change of the rock in water after the rock swells by water absorption. The structure of the device for measuring the free swelling rate and the water content of the rock is largely simplified by adoption of technical means such as sealing and packaging of a rock sample to be measured with rubber film. The device has characteristics of simple structure, convenient raw material selection, low manufacturing cost, convenient operation, and the like. The whole experiment device is small in systemic error. Experiment results are true, reliable and accurate. The device is suitable for laboratory use, and particularly can be used for simultaneously perform measurement of the free swelling rate and the water content of soft rocks.

The invention discloses an automatic feeding device for beekeeping, which includes a feeding seat and a sugar injection and water outlet on the feeding seat. The bottom of the sugar injection and water outlet is provided with a rotating hole, and a rotating shaft is clamped in the rotating hole, and the rotating shaft is fixed. On both sides of the head of the floating rod, the tail of the floating rod is connected with a float, and a plug is movably fixed on the floating rod corresponding to the longitudinal direction of the sugar injection and water outlet. The invention is simple in structure, easy to use, removes the spring in the original automatic feeding device, and solves the problem that the water injection is not enough to complete the automatic feeding due to the small volume of the water tank and the spring is easy to rust, which causes the short service life of the device and affects the health of bees. The invention of the automatic feeding device uses the principle of Archimedes to make the float receive upward buoyancy, which drives one end of the floating rod to rotate, so that the fixed plug on the other end of the floating rod blocks the sugar injection and the water outlet to complete the purpose of automatic feeding. The use of this device The cost is reduced, the service life is prolonged, and the utility model is convenient for popularization and use.
