Abstract: A tethered charging and recharging (TCR) drone assembly system is provided. The TCR drone assembly system may be a nurse vehicle-based, a master/slave vehicle-based, a stationary structure and/or free standing TCR drone assembly system. The TCR drone assembly system is especially suitable for use on moving vehicles, for example, a self-propelled conventional type vehicle operated by an operator and/or autonomous or slave autonomous vehicle with no operator on board. The TRC drone assembly system may quickly couple and may deliver energy charges, recharges or other types of power propellants to vehicles while the vehicles are stationary or in motion. The assemblies are especially suitable for providing power to vehicles when only limited downtime of the vehicles is desired. The assemblies are suitable for use in, for example, the agricultural, construction, defense or other industries.

Abstract: An autonomous spraying platform is provided. The autonomous spraying platform has a main frame platform supported by a first and a second wheel in tandem. Supported by the main frame platform and extended perpendicular thereto are extended booms having multiple movable and/or telescoping arms which touch the ground on each side by small wheels for balance and sensing of the ground. Liquids, foams or powders, which may carry pesticides, herbicides, insecticides, fungicides, fertilizers or other pro-growth ingredients, may be dispensed across the bottom edge of the extended booms. The main frame platform may be controlled locally by sensors utilizing GPS (or other positioning technology) or remotely by a computer or even alive operator. The device may allow for real-time precise delivery of pro-growth materials to plants.
