Welcome to our countdown of the top 10 bizarre robots we’ve engineered, where science meets the surreal. From autonomous machines that munch on foliage to robot jockeys that steer camels, this list showcases the strangest creations pushing the boundaries of robotics.
Top 10 Bizarre Robots Overview
10 Robots That Eat Plants And Maybe Humans
The Energetically Autonomous Tactical Robot, better known as EATR, was a joint effort by Cyclone Power Technologies and Robotic Technology Inc. for DARPA, the U.S. defense agency that loves a good challenge. Their brief was simple yet ambitious: design a field‑ready robot that could stay operational for months without needing a plug or a fuel stop.
The solution was as wild as it was clever – a machine that chews on vegetation, converts the plant matter into usable fuel, and powers itself indefinitely. To make the whole thing work, engineers bolted a chainsaw onto its chassis, just in case it needed to slice down trees into bite‑size fuel chunks.
Unsurprisingly, the public started to wonder whether that chainsaw was a covert weapon. Rumors swirled about the robot possibly chopping up fallen enemy combatants for extra energy, and some even asked the unsettling question: what would the robot do if there were no dead bodies around? Would it take matters into its own metallic hands?
Both Cyclone Power, Robotic Technology, and DARPA stepped in to squash the speculation, confirming that the EATR is a strict herbivore. It refuses to consume any human tissue, whether living or deceased, and there are no plans to change its diet.
9 Robots That Ride Camels
Camel racing has long been a beloved pastime across the Middle East, but the sport has a dark side: it traditionally required child jockeys, often abducted from impoverished families in Bangladesh, India, and Pakistan. International pressure, especially from UNICEF, forced a ban on child jockeys in 2005, prompting a high‑tech solution.
Enter the robot jockey – a compact, remotely‑controlled device that sits atop the camel and delivers commands via a walkie‑talkie. Operators stationed on the sidelines can issue voice instructions or press pre‑programmed buttons to steer the animal, control its speed, and even administer a whip.
The technology also allows the robot to send real‑time telemetry back to the operator, reporting the camel’s health metrics and GPS location. Unfortunately, some operators still resort to illegal tactics, such as delivering electric shocks to spur the animal into a faster pace, a practice punishable by a three‑month prison sentence but still reported to occur.
Despite the controversy, the robotic jockey has become a staple of modern camel racing, replacing a centuries‑old tradition with a futuristic, albeit ethically complex, alternative.
8 A Robot That Feeds Its Wearer Tomatoes
The Tomatan is a truly peculiar piece of wearable tech created by Kagome, Japan’s heavyweight in tomato juice and ketchup. Designed for runners, the robot straps onto the shoulder and features a bright red, tomato‑shaped head that dispenses fresh tomatoes directly into the wearer’s mouth as they sprint.
Tomatan’s mechanism works like a tiny kitchen: the robot’s mouth releases whole tomatoes, which are then caught by two rotating arms that guide the fruit straight to the runner’s waiting mouth. For those who crave a snack on the go, the device promises a burst of lycopene‑rich nutrition mid‑run.
Kagome didn’t stop there; they also released a smaller sibling called the Petit‑Tomatan, which tucks onto the runner’s back like a backpack. Both models claim to combat fatigue by delivering the antioxidant power of tomatoes straight to the bloodstream.
However, the Tomatan weighs in at a hefty 8 kg (18 lb), while the Petit‑Tomatan is still a solid 3 kg (7 lb). For marathoners obsessed with shedding every gram, the extra weight might be the very thing that saps their stamina.
7 Robot Armed With A Pistol
Dogo, a compact tracked robot from Israel’s General Robotics, is built for agility. Its low profile lets it slip under vehicles, navigate tight corners, and even climb stairs, making it a handy tool for reconnaissance and rescue missions.
What sets Dogo apart is its side‑mounted Glock 26 pistol. An operator can fire up to five rounds in two seconds, with a total capacity of 14 rounds. The weapon is engineered to stay steady despite the robot’s movement, delivering pinpoint accuracy with minimal recoil.
6 Robot That Hikes
hitchBOT is a friendly‑looking robot that literally hitchhikes across continents. The original Canadian version logged over 10,000 km (6,200 mi) from Halifax to Victoria in 2014, catching 19 rides over a 26‑day adventure. A year later, it crossed several European cities, delighting travelers along the way.
A second hitchBOT set out from Salem, Massachusetts, aiming for San Francisco. Unfortunately, its journey was cut short in Philadelphia when vandals stole its head and destroyed the rest of its body, leaving the robot beyond repair.
The disappearance was first noticed when the robot vanished from the public map that tracked its progress. hitchBOT captured photos every 20 minutes, so it might have photographed its attacker—but the 20‑minute delay likely gave the perpetrator enough time to flee.
5 Robots That Smoke Cigarettes
Two smoking robots have made history. The first, Elektro, towered at 213 cm (7 ft) and debuted at the 1939 World’s Fair alongside his canine companion Sparko. While Sparko could sit and bark, Elektro could walk, count, and, oddly enough, puff on a cigarette.
Elektro now resides at Ohio’s Mansfield Memorial Museum, whereas Sparko vanished after 1957. Decades later, Harvard researchers built a chain‑smoking robot capable of lighting up to 12 cigarettes in one sitting, mimicking human puffing patterns that can be adjusted for speed.
The Harvard bot was designed as a research tool to study the physiological impacts of smoking, offering a controllable platform for experiments without endangering real humans.
4 Robots That Comfort Dying People
When a person’s loved ones can’t be present at the end of life, Dan Chen of the Rhode Island School of Design created the Last Moment Robot to fill that void. The robot gently grasps the patient’s forearm, introduces itself in a soothing voice, and offers comforting words.
Hello [Name]. I am the Last Moment Robot. I am here to help you and guide you through your last moment on Earth. I am sorry that your family and friends can’t be with you right now, but don’t be afraid. I am here to comfort you.
The ethical debate is still alive: should a machine replace human companionship in a person’s final hours? The robot has yet to be tested with actual patients, and there are no market plans for its release.
3 Robots That Duel
When robot combat grew from hobbyist battles in the 1990s to full‑scale showdowns, the 2017 clash between America’s MegaBots and Japan’s Suidobashi Heavy Industries marked the pinnacle. The two giants, Eagle Prime and Kurata, faced off after a two‑year build‑up.
Eagle Prime, a $2.5 million, 12‑ton, 5‑meter‑tall behemoth, wielded a massive chainsaw. Its opponent, Kurata, weighed 6.5 tons and stood 4 meters tall. After a dramatic first round where MegaBots’ smaller MK II fell, Eagle Prime cut through Kurata, securing the victory.
The duel captured the imagination of fans worldwide, proving that giant, weaponized robots could indeed battle in real life.
2 The Robot That Always Wins Rock‑Paper‑Scissors
The Janken robot, engineered at the University of Tokyo, never loses a game of rock‑paper‑scissors. It uses high‑speed gesture recognition to detect the human’s hand shape a split‑second before the move is completed, then instantly mirrors a winning gesture.
The original 2012 version lagged by about 20 milliseconds, delivering its winning hand just after the opponent. The upgraded model shrank that delay to virtually zero, making it impossible for a human to outplay the machine.
1 Robot That Pretends To Have The Swine Flu
Developed by an unnamed Japanese firm, the swine‑flu robot mimics every symptom of the H1N1 virus, from fever and sweating to convulsions. Built to a human size and covered in skin‑like material, it serves as a training dummy for healthcare workers learning to treat flu patients.
The robot’s condition fluctuates based on the care it receives: proper treatment stabilizes it, while incorrect handling can lead to its simulated death. It stands as the first robot designed to replicate a single disease’s full symptomology.
