WiFi-Sensoren für Bienen


Shyam Gollakota von der Uni Washington haben ein WiFi-Sensor-System in Form eines „Rucksacks“ für Hummeln und Bienen entwickelt. Herkömmliche Dronen zur Überwachung von Feldern in der Agrarwirtschaft haben nur eine begrenzte Energie-Kapazität und fliegen nur 20 Minuten, während Hummeln mit diesem Sensor-Pack stundenlang rumfliegen können. Ein fliegendes Bio-Internet-of-Shit-System und ein weiterer Schritt zur Roboter-Biene, so we don’t need to give a flying (!) fuck about dying insects.

“Drones can fly for maybe 10 or 20 minutes before they need to charge again, whereas our bees can collect data for hours,” said senior author Shyam Gollakota, an associate professor in the UW’s Paul G. Allen School of Computer Science & Engineering. “We showed for the first time that it’s possible to actually do all this computation and sensing using insects in lieu of drones.”

Paper: Living IoT: A Flying Wireless Platform on Live Insects

Sensor networks with devices capable of moving could enable applications ranging from precision irrigation to environmental sensing. Using mechanical drones to move sensors, however, severely limits operation time since flight time is limited by the energy density of current battery technology. We explore an alternative, biology-based solution: integrate sensing, computing and communication functionalities onto live flying insects to create a mobile IoT platform.

Such an approach takes advantage of these tiny, highly efficient biological insects which are ubiquitous in many outdoor ecosystems, to essentially provide mobility for free. Doing so however requires addressing key technical challenges of power, size, weight and self-localization in order for the insects to perform location-dependent sensing operations as they carry our IoT payload through the environment. We develop and deploy our platform on bumblebees which includes backscatter communication, low-power self-localization hardware, sensors, and a power source. We show that our platform is capable of sensing, backscattering data at 1 kbps when the insects are back at the hive, and localizing itself up to distances of 80m from the access points, all within a total weight budget of 102mg.
