Horned 'Threehalves' Robot Unveiled For Wildfires And Toxic Disaster Sites

California robotics startup Satyress Robotics has released promotional images of a two-meter-tall centaur-style robot designed for remote operation in hazardous environments including wildfires and toxic zones. The company announced the machine, named Threehalves, combines a humanoid upper body with a four-legged base and features modular tool attachments. According to the company website, Threehalves is teleoperated and intended as a force multiplier for skilled workers rather than a replacement. The design uses friction-braked joints that consume no power when motionless and provide failsafes if motor control is lost. A quick-connect wrist system supplies power and air to tools built for humans, and limbs and tools are assembled from three interchangeable parts allowing field swaps in minutes. The horned head houses wide-angle cameras for redundancy if actuator encoders fail. Safety mechanisms include fail-on air brakes and pin locks that immobilize the robot if system air pressure is lost. Shared pressurized reservoirs in the chest plate and body can be pierced to stop the machine instantly. Multiple reports describe the circulating images as promotional designs. No public demonstrations of a fully operational unit, price, commercial release date, or OSHA compliance details have been announced.
