A new study reveals how we could design robots to think like bees. Honey bees excel in weighing effort against reward and risk, quickly determining which flowers can provide sustenance for their colony. A study recently published in the journal eLife illustrates how eons of evolution have fine-tuned honey bees to make swift judgments while minimizing danger.
This research sheds light on the workings of insect minds, the evolution of human cognition, and offers insights for improved robot design.
The paper presents a model of decision-making in bees and outlines the paths in their brains that enable fast decision-making. The study was led by Professor Andrew Barron from Macquarie University in Sydney, and Dr. HaDi MaBouDi, Neville Dearden, and Professor James Marshall from the University of Sheffield.
“Decision-making is at the core of cognition,” says Professor Barron. “It’s the result of an evaluation of possible outcomes, and animal lives are full of decisions. A honey bee has a brain smaller than a sesame seed. And yet she can make decisions faster and more accurately than we can. A robot programmed to do a bee’s job would need the backup of a supercomputer.
“Today’s autonomous robots largely work with the support of remote computing,” Professor Barron continues. “Drones are relatively brainless, they have to be in wireless communication with a data center. This technology path will never allow a drone to truly explore Mars solo – NASA’s amazing rovers on Mars have traveled about 75 kilometers in years of exploration.”

Bees need to work quickly and efficiently, finding nectar and returning it to the hive while avoiding predators. They need to make decisions. Which flower will have nectar? While they’re flying, they’re only prone to aerial attack. When they land to feed, they’re vulnerable to spiders and other predators, some of which use camouflage to look like flowers.
“We trained 20 bees to recognize five different colored ‘flower disks’. Blue flowers always had sugar syrup,” says Dr. MaBouDi. “Green flowers always had quinine [tonic water] with a bitter taste for bees. Other colors sometimes had glucose.”
“Then we introduced each bee to a ‘garden’ where the ‘flowers’ just had distilled water. We filmed each bee then watched more than 40 hours of video, tracking the path of the bees and timing how long it took them to make a decision. “If the bees were confident that a flower would have food, then they quickly decided to land on it taking an average of 0.6 seconds),” says Dr. MaBouDi. “If they were confident that a flower would not have food, they made a decision just as quickly.”
If they were unsure, then they took much more time – on average 1.4 seconds – and the time reflected the probability that a flower had food.
The team then built a computer model from first principles aiming to replicate the bees’ decision-making process. They found the structure of their computer model looked very similar to the physical layout of a bee brain.
“Our study has demonstrated complex autonomous decision-making with minimal neural circuitry,” says Professor Marshall. “Now we know how bees make such smart decisions, we are studying how they are so fast at gathering and sampling information. We think bees are using their flight movements to enhance their visual system to make them better at detecting the best flowers.”
AI researchers can learn much from insects and other ‘simple’ animals. Millions of years of evolution have led to incredibly efficient brains with very low power requirements. The future of AI in the industry will be inspired by biology, says Professor Marshall, who co-founded Opteran, a company that reverse-engineers insect brain algorithms to enable machines to move autonomously, like nature.

especially when the decision comes about its gender.
Well duh-—that’s what they’re made to do, tell flowers apart-—let’s see if they can drive a car, use a computer, a smart phone, etc.
I’ll leave the pollinating to them...but everything else we do smarter and better.
(only drones mate......)
I for one welcome our future robot insect overlords.
The click-bait title does not match the article.
The Killer Bees! Yesssss!
Considering the low IQ savagery of many people, I have no doubt they can.
Ha, ha, coach was buzzing off.
Reggie Jackson is a buzz-off?!!

That’s because they don’t rely on technology.
It’s because they don’t have committes.
well formedness criteria for choosing outcomes:
ratio of benefit to harm
ratio of benefit to risk of harm
ratio of benefit to cost
I’d BEE-lieve it! :)
“I for one welcome our future robot insect overlords.”
LOL! :)
