The Terrifying New Robot Built to Save Lives

Major technological advances in robotics are often met with two distinct responses. Some people are excited by the new possibilities the robots offer, while others worry about them taking jobs away from humans. A robot recently developed by a company called Satyress doesn’t try to hide anything — its robot was designed to take certain jobs away from people. But in this case, it’s a good thing. The robot, named Threehalves, was designed to handle dangerous jobs controlling wildfires or rescuing people from collapsed buildings where it is unsafe to send humans in.

It’s probably for the best that Threehalves isn’t meant to work closely with people. This 6 ½-foot-tall steel centaur wielding a chainsaw is pure nightmare fuel. It may be able to pull victims out from a collapsed structure after an earthquake, but there’s a decent chance those same victims would take one look at Threehalves and decide they’d rather take their chances under the rubble.

Rather than walking on two legs like a humanoid robot, Threehalves combines a humanoid upper body with a four-legged base. This unusual design gives it the stability needed to navigate rough terrain while still allowing it to use familiar handheld tools. Instead of being built around a fixed pair of arms, the robot features a modular limb system that lets operators quickly swap attachments such as chainsaws, drills, and screwdrivers depending on the task at hand. Each tool is made from three interchangeable sections, making repairs and reconfiguration much simpler in the field.

The robot is controlled entirely by a remote operator using a joystick, keeping emergency personnel well away from unstable buildings, active fire lines, or other hazardous environments. According to Satyress, the guiding philosophy behind the project is simple: no job is worth risking a human life. Rather than replacing skilled workers, Threehalves is intended to let those workers perform dangerous tasks from a safe distance.

Satyress also incorporated several safety systems into the design. An operator can immediately freeze the robot's movements with a raised-palm gesture. If that electronic safeguard were ever to fail, Threehalves includes a pneumatic braking system powered by pressurized tanks mounted on its chest and back. Puncturing one of those tanks activates the brakes, physically locking the robot in place as a last-resort emergency stop.

Satyress has not yet announced pricing, commercial availability, or whether the robot will ultimately meet the regulatory requirements needed for widespread emergency service use. Even so, Threehalves offers a glimpse at how robotics could eventually help keep first responders out of harm's way while still getting the job done.
