A towering centaur robot designed to enter disaster zones has gone viral, but its demonic appearance and ability to wield a chainsaw have people questioning whether they actually want it to rescue them.
California robotics company Satyress is developing Threehalves, a seven-foot robot with a humanoid upper body, four-legged chassis, glowing eyes and a goat-like head covered in horns.
The machine is being built for dangerous environments where sending a human would be too risky, including wildfires, rubble searches, toxic areas and confined spaces.
However, when photos of Threehalves circulated on X, its intimidating design and chainsaw attachment left the internet fearing a robot uprising more than celebrating the potential rescue applications.

“Brother if this comes out of the smoke to rescue me from a wildfire I am running INTO the flames,” one user joked.
“‘A robot, but we make it look as demonic as possible,’” another wrote.
Others were even less convinced by the machine’s intended purpose. “You can not convince me this thing won’t be starting fires,” one viewer said.
“Imagine being dismembered limb by limb from a robotic centaur with a chainsaw,” another added.

Satyress says it is taking a “teleoperation focused approach,” allowing a skilled worker to control the robot remotely using a computer and joystick.
Its quick-connect wrists can also be fitted with tools such as chainsaws, drills and impact guns, with power and compressed air supplied directly by the robot. The four-legged base is intended to provide greater stability than a traditional two-legged machine.

Satyress appears well aware of the risks. Its website openly warns that Threehalves is “more dangerous than it looks” and describes several physical failsafes.
The robot’s brakes and locking pins are designed to immobilize it if air pressure is lost. Reservoirs in its chest and body can also be pierced to stop it immediately.
Even the horns serve as a safety measure. They can make it harder for Threehalves to pass through standard doorways, with larger versions available to prevent it from entering buildings entirely.
Satyress has not announced a price or release date for Threehalves.
This isn’t the first scary robot to have the internet on edge. Last year, Chinese robotics startup EngineAi sparked waves of Judgment Day jokes after unveiling its T800 humanoid robot that literally kicked its own CEO across the room.
