Nano Air Vehicle The current model is a prototype and more development is required before any decisions are made on its deployment. Keennon said he expected the flight time to improve as the spybot develops, and said he envisaged it could be used for reconnaissance purposes in around a decade. He also said the final version is unlikely to look like a hummingbird, which is rare even in parts of the US, and he thinks a sparrow would be a better choice.The US military has funded the project, giving AeroVironment around $4 million since 2006. (PhysOrg.com) — A prototype robot spy “ornithopter,” the Nano-Hummingbird, has successfully completed flight trials in California. Developed by the company AeroVironment Inc., the miniature spybot looks like a hummingbird complete with flapping wings, and is only slightly larger and heavier than most hummingbirds, but smaller than the largest species. © 2010 PhysOrg.com More information: www.avinc.com/nano Hummingbird flight an evolutionary marvel Citation: Robot hummingbird passes flight tests (w/ Video) (2011, February 18) retrieved 18 August 2019 from https://phys.org/news/2011-02-robot-hummingbird-flight-video.html
Kolkata: A sustainability code and verification system for the country’s tea sector Tuesday said it has verified 608 million kgs of tea till February 2019, which is almost half of the total tea produced in the country annually.
