Abstract:
A portable unmanned air vehicle and launcher system is provided that includes a foldable unmanned air vehicle having a pressure tube; a launch gas reservoir for holding launch gas; a launch tube operatively connected to the launch gas reservoir and having a free end that is positioned in the pressure tube of the air vehicle; a free piston positioned within the launch tube; and a free piston stop to prevent the free piston from leaving the launch tube. A first portion of the launch gas in the launch gas reservoir is released into the launch tube and forces the free piston from an initial position to an end position at which the free piston is stopped by the free piston stop.
Abstract:
An obstacle avoidance system for a stabilized aerial vehicle and a method of controlling same are provided. Using low angular resolution obstacle proximity data, such as from low angular resolution obstacle detection sensors, when a determination is made that an operator command to a vehicle propulsion system will result in a collision, the system overrides the operator command and substitutes an avoidance speed command and avoidance heading, while maintaining operator situational awareness, in a manner that is transparent to the operator. In an implementation, examination of objects requires the obstacle avoidance system to allow the vehicle to get close to obstacles. A human-portable aerial vehicle according to an implementation can be used for building surveillance, route inspection, surveillance of windows/hallways/rooftops, power distribution towers, pipelines, bridges, buildings or close examination of suspect objects.
Abstract:
A rotary wing vehicle (1) includes a body structure having an elongated tubular backbone or core (40), and a counter-rotating coaxial rotor system (3, 5) having rotors with each rotor having a separate motor (54, 61) to drive the rotors about a common rotor axis of rotation (7), The rotor system is used to move the rotary wing vehicle (1) in directional flight.
Abstract:
The embodiments herein disclose a personal UAV kit for storing, preparing and remote control of micro UAVs. The UAV kit includes a base unit, a control unit and at least one UAV. The UAVs can typically be a winged aircraft with foldable wings or a helicopter with a two-bladed or foldable rotor. The base unit comprises UAV compartments for housing at least one UAV, a bay for storing the control unit, batteries and electronic components for charging, communication, control and processing and storing of data. In addition, the system includes an eye near display device for viewing system information and sensor data, typically live video, transmitted from the UAV.

Abstract:
A drive assembly for use with a mechanical flying or walking device comprises an articulated member (7) having first and second portions (7a, 7b) arranged such that the portions move relative to each other, and a drive mechanism (9) for imparting motion to the articulated member. The drive mechanism (9) comprises: a drive member for imparting a cyclic motion on the articulated member; and a control member for controlling, in a predetermined manner, the relative position of the first and second portions during each cycle of the cyclic motion of the articulated member. In the case of a mechanical flying device, two such drive assemblies may be provided, the articulated member of each assembly forming a wing.
