A robot some reckon looks straight out of a horror flick — complete with glowing eyes, horns and a chainsaw arm — has gone viral on social media these past couple of weeks. Online chatter has branded it creepy, demonic and even “satanic.”
That quadruped robot’s name is Threehalves, a four-legged centaur-style machine from California startup Satyress Robotics. Founder Beau Gaston, a 40-year-old engineer based in rural Auburn, built the roughly seven-foot, 240-pound mechanical beast deliberately to intimidate. He wanted something that screams “dangerous tool, not friendly toy” so people keep clear while it’s doing its thing.
The pitch-black finish, goat-like head and horns (which double as camera mounts) deliver that vibe well. The company name is inspired by the female satyr of myth, and the robot’s half-human, half-goat, half-horse form gives it its name.
Threehalves exists to keep humans out of harm’s way in wildfires, collapsed buildings, toxic sites and forestry work — the deadliest job in the United States. A skilled operator steers it by joystick from a safe, line-of-sight distance while the quadruped swaps tools via quick-connect wrists that feed power and compressed air straight into chainsaws, drills and impact guns. No fancy autonomous AI here, Satyress says the point is giving experienced tradespeople “superpowers” while they stay clear of falling branches or flames.
“I think the design aesthetic should make it clear to be cautious around it and if you don’t know what it is stay away from it,” said Gaston. “I am really only looking to do the most dangerous type of work with this thing.”
The website has sat online since for over a year, yet the robot only exploded into public view in late July. Right now it’s still at the component-testing stage, its legs aren’t fully working yet and a commercial version sits more than two years off.
Certain critics online think the look is overkill and could terrify anyone it tries to rescue, but the timing of its growing public awareness feels sharp as wildfires are currently raging across California and western Canada.
Anybody who is afraid of this creepy creation going rogue can take comfort in knowing that shooting it once in the chest will immediately immobilise it. Threehalves runs off of a compressed air tank in its core.
