A type of a waste item is identified at a waste collection location using at least a drone-based system. The drone-based system characterizes one or more properties of the waste item. Based on the identified type and the one or more properties, the drone-based system performs a risk assessment based on human health of content of the waste item. One or more actions are taken by one or more drones of the drone-based system based on the risk assessment of the content of the waste item.

A movable device includes: at least one lift generating unit for generating a pressure difference between opposite sides thereof to generate a lift force; a movable device body connected to the lift generating unit to be movable by the lift force generated by the lift generating unit; and at least one supply duct, the number of which corresponds to the number of the lift generating unit. One end of the supply duct is disposed on one side of the lift generating unit and, when the lift generating unit operates, fluid is suctioned through the other end of the supply duct to be supplied into the lift generating unit.

Aspects concerning a robot system is provided comprising a ground vehicle, an aerial vehicle capable of flight, and a tether connecting the aerial vehicle to the ground vehicle, wherein the tether comprises on or more Bowden cables, each having an inner cable connected at one end to a respective motor of one or more motors of the ground vehicle and at another end to a component of the aerial vehicle, wherein the ground vehicle comprises a motor controller configured to control movement of the component of the aerial vehicle by controlling the one or more motors.

An unmanned aerial vehicle (UAV) has a multicopter section for flying in air with an attached blower section for generating an air stream for blowing dust off surfaces. A flight controller controls the multicopter section, a blower controller controls the blower section, and a power supply supplies power to the multicopter and blower sections. The flight controller and the blower controller are connected, and the blower controller is adapted to supply blower control commands to the flight controller to compensate for the thrust of the air stream from the blower section by flight control of the multicopter section. The UAV may be enclosed by a protective cage in the form of a meshed polyhedron, wherein the rods of the meshes are elastically connected at the respective nodes.

1. Method for controlling a flying body for cleaning surfaces 2.1. Flying bodies can cover large distances between arrangements of smooth and curved surfaces without requiring manual manipulation. This reduces personnel requirements and enables large surfaces to be maintained, for example solar power stations, in a fully automated manner. 2.2. The method for controlling a flying body for cleaning surfaces consists of detecting the surrounding surfaces of an object to be cleaned, directing the flying body with respect thereto and structuring the flight path. As a result, the surface can be cleaned particularly efficiently and, if needed, worked on further. 2.3. Said method for controlling a flying object for cleaning surfaces is suitable for use on glass facades or on solar power stations, particularly in arid regions.

A cleaning apparatus for cleaning fa?ades includes an aerial vehicle with rotors and a cleaning device attached to the aerial vehicle. This cleaning device can clean fa?ades easily, mechanically with brushes or with a cleaning medium such as for example deionized water or dry ice.

An apparatus comprising a contactless battery synchronous power and a battery management system (BSP-BMS) is disclosed. This system includes a battery monitoring unit for monitoring the state of the batteries and a synchronous power unit for controlling the intensity and direction of current during both, charging and discharging processes, including one or several opto-inductive discs for the wireless energy transfer and fast and a lightweight communication scheme. The full system disclosed in this invention is very small in size, lightweight, cost effective and reliable due to its scalable structure, easy parallelization of current control elements and paths, and local and reliable opto-inductive coupling. The invention is aimed at universal, fast and automated charge processes and internal stored energy management for unmanned autonomous vehicles (UAVs) but it can be an effective solution for manned electric vehicles like electric bikes, electric motorcycles or other electric powered vehicles.

Disclosed is a method and apparatus for performing high volume washing, namely, using drones to perform cleaning services. A drone is navigated about a cleaning path; the cleaning path being either pre-defined or delineated in real-time. A cleaning solution is pumped to a solution distribution mechanism of the drone, wherein the cleaning solution is directed onto the surface to be cleaned. The solution is stored in a supply tank that may be integrated into the body of the drone or outfitted as a standalone structure. A temperature regulator is integrated with the supply tank in order to control a wash temperature of the cleaning solution. The solution distribution mechanism may be rotatable about 360 degrees. A camera array observes a spray area of the solution distribution mechanism, wherein a live feed is transmitted to a monitoring unit.

Described embodiments include an unmanned aerial vehicle and a method. The unmanned aerial vehicle includes an airframe and a rotary wing system coupled with the airframe and configured to aerodynamically lift the vehicle in the air. The unmanned aerial vehicle includes a flight controller configured to control a movement of the vehicle while airborne. The unmanned aerial vehicle includes a cleansing controller configured to manage a removal of a surface contaminant from a selected portion of a surface of an external object using an airflow generated by the rotary wing system.
