Powered airships for future robotics

Article Abstract:

The current development of airships which fly themselves means that unmanned airships could be used for aerial photograhpy of crop treatment, chemical application, and aerial television pictures of sports events. Modern airships tend to be smaller than those of the 1930s. GEC Avionics has overcome the problems associated with flying airships manually with Westinghouse's 'Sentinel' design has four fins placed diagonally, which prevent the effect of solar heating on buoyancy, the rocking motion of an airship, and its being steered off course by the wind. GEC Avionics has just finished a technology demonstrator of a 'Sentinel 5000' for the US Navy. It has also made an automatic pilot system for a 220 ft long Westinghouse 'Sentinel 1000' airship. The new airship developed by Air Rover (Anglesey, UK) is also discussed.

Wireless sensor data best sent by heat

Article Abstract:

The Cranfield Impact Centre in the UK has developed a system for transmitting sensor data without wires. The system, which is being used for new motor vehicle development studies, uses infrared diodes to send error-free information. Infrared data transmission has several advantages: it is intrinsically safe, does not need a licence, is inexpensive, and does not have the same problems with interference that radio-based systems have. Cranfield's system is being used to measure and log the torque on the axles of new four-wheel-drive vehicles in field tests.
