Underwater robots to autonomously dock mid-mission to recharge and transfer data — ScienceDaily

Robots can be amazing tools for search-and-rescue missions and environmental studies, but eventually they must return to a base to recharge their batteries and upload their data. That can be a challenge if your robot is an autonomous underwater vehicle (AUV) exploring deep ocean waters.

Now, a Purdue University team has created a mobile docking system for AUVs, enabling them to perform longer tasks without the need for human intervention.

The team also has published papers on ways to adapt this docking system for AUVs that will explore extraterrestrial lakes, such as those of Jupiter and Saturn’s moons.

“My research focuses on persistent operation of robots in challenging environments,” said Nina Mahmoudian, an associate professor of mechanical engineering. “And there’s no more challenging environment than underwater.”

Once a marine robot submerges in water, it loses the ability to transmit and receive radio signals, including GPS data. Some may use acoustic

Fortem Technologies Adds New Capabilities to Autonomously Capture a Wider Array of Drone Threats, Including Faster Moving Fixed Wing Drones

Pleasant Grove, UT, Sept. 16, 2020 (GLOBE NEWSWIRE) — Fortem Technologies Inc., a leader in airspace security and defense for detecting and defeating dangerous drones, announced today advancements to its SkyDome® System software that allow the Fortem DroneHunter® to autonomously shift into one of three various modes to best defeat a threatening drone. DroneHunter, the world’s premier AI-driven interceptor drone, autonomously determines whether to chase, attack or defend against the threatening drone depending on the drone’s size, speed and trajectory. These advancements allow DroneHunter to pursue and safely capture an even wider range of drone threats including faster fixed wing drones.

When in defense mode, the DroneHunter maneuvers in front of the target drone, anticipating its approach. Once in range, DroneHunter fires the NetGun precisely as the target attempts to pass. The defensive mode position also facilitates a radically faster detect-to-capture-time, as the time previously required to get behind the
