Bee-Inspired Navigation Robot Pinpoints Its Home Using a Neural Network Saving $1000s of dollars on compute by simulation of the Bee. 
How a tiny drone learns to fly home like a honeybee without heavy maps or massive computing power In the world of robotics, navigation has long been a heavyweight affair. Most autonomous drones and ground robots rely on sophisticated systems like SLAM (Simultaneous Localization and Mapping) that build detailed digital maps of their surroundings in real time. These approaches deliver pinpoint accuracy, but they come at a steep cost in processing power, memory, and energy, making them impractical for truly small, lightweight, or long-endurance robots. Now, a breakthrough reported in Nature offers a far lighter alternative. In a research paper titled “Efficient robot navigation inspired by honeybee learning flights,” a paper demonstrated a flying robot that uses a bee-inspired strategy to find its way home, even after flights of hundreds of meters, using neural networks small enough to fit in a few kilobytes. The accompanying News and Views commentary by neuroethologist Barbara Webb of the University of Edinburgh highlights just how elegant and efficient this bio-mimetic approach is compared to conventional robot navigation. Learning to Fly Home the Bee Way Honeybees are masters of long-distance navigation. Before embarking on a foraging trip that can span kilometers, young bees perform short “learning flights” or “orientation flights” in a looping, spiral pattern around the hive. During these brief excursions, they memorize visual snapshots of the surrounding landscape while keeping track of their position relative to home using an internal sense of direction and distance (path integration). The new robotic system, dubbed Bee-Nav, copies this exact behavior. 1 Learning phase: The drone performs a short exploratory flight around its “home” base. As it flies, an omnidirectional (360 degree) camera captures panoramic images while the robot simultaneously tracks its position using a simple path-integration system (based on optical flow from the camera, a laser rangefinder for height, and a gyroscope for heading). 2 Training phase: These images are paired with the corresponding “home vector” (direction and distance back to base) to train a compact neural network in a self-supervised manner. No external labels or GPS are needed. 3 Mission phase: The drone flies out on a task, potentially hundreds of meters away, updating its position estimate via path integration. 4 Return phase: On the way back, it heads straight toward the estimated home location using path integration. When it enters the small “Learned Homing Area” (LHA) near base (typically just 0.25 to 10 percent of the total area explored), the visual neural network takes over, outputting a corrected home vector that cancels out accumulated drift and guides the drone to within 0.5 meters of home. The neural networks are astonishingly small: a basic convolutional model uses just 3.4 kilobytes (868 parameters); a more advanced attention-based version uses 42 kilobytes. Both run comfortably on a low-power Raspberry Pi 4. Real-World Performance That Impresses In simulations and physical tests, Bee-Nav proved remarkably robust: •Indoor arenas (10 by 10 meters and 30 by 40 meters): 100 percent success rate across dozens of flights, even with obstacles. Homing error was typically under 40 degrees in heading and 1.5 meters in distance. •Outdoor flights (up to 600 meters in windy conditions of 5 to 10 meters per second): 100 percent success for 30 to 110 meter missions and about 70 percent success for 200 to 600 meter flights. The drone still returned to within 0.5 meters of home in most cases. These results were achieved without GPS, without building any map, and without high-end GPUs, just a tiny drone carrying minimal computing hardware. 1 of 2

This never happened. As a rule I try not to disparage individual people from my old business. It’s rude to do so, unless they say something beyond the pale. Ms. Midler and I disagree about a lot of things, but I prefer to appreciate her extraordinary talent, and leave it at that.

🚨JAMES WOODS JUST HUMILIATED THE WOKE, TRUMP-HATING DIVA BETTE MIDLER IN THE MOST SAVAGE, CLASSIC ROAST OF ALL TIME AT A CHARITY EVENT — SHE NEVER SAW IT COMING! Follow @UnmaskTheSys The radical leftist hag couldn’t keep her big mouth shut. While James Woods was giving a speech and said “we should all show our support,” Midler lost her shit and screamed “You support a monster!” — because Woods dares to back President Donald Trump. Woods didn’t even flinch. He looked right at her and delivered the perfect kill shot: “Waitress, could you get this nice lady a double Grey Goose neat? She doesn’t seem to know where she is.” Then he calmly finished his speech — which had ZERO to do with politics — and dropped one final mic on the bitter old bag: “I’d like to thank Ms. Bette Midler for demonstrating once again that the left has no class.” Absolute legend. One quick, effortless burn, and the entire room watched the unhinged Hollywood leftist get publicly owned and exposed as the classless clown she is. This is why the left can’t stand real men with actual wit. Share this everywhere if you’re loving these smug, entitled liberal divas getting absolutely wrecked! Follow @mcafeenew for more drops.

The bionic skin Robots will hit the headlines in September 2026. Love it or not love it, get used to it. There are 79 companies building this now. No skin robots will ultimately be exception and not the rule. And yes some we be very “personal” robots. I hope we mature—fast.

I love being on his show because my pal @greggutfeld is the hardest working man in show business. For his size. Meanwhile my old friend @PlanetTyrus is the hardest working man in show business, period. And the strongest lifter, too. Guess which one I fear?
