Video footage released by the institute on July 24 shows the ARMstrong Dex, developed by the Korea Atomic Energy Research Institute (KAERI) using its mechanical arm to pitch the 500-kilogram bottle from about 10 feet away. While the test may appear simple, it means the robot has vital skills in an emergency, New York Post said.

In disaster scenarios, where access is limited or too dangerous for humans, the ability to deliver essential supplies such as water, medical kits and communication devices with speed and precision could save lives.

Engineers equipped ARMstrong Dex with the ability to calculate throwing force and trajectory in real time for accurate delivery. Earlier trials showed the robot performing dead-hang pull-ups with a 44-pound weight and single-arm curls with 88 pounds. Engineers used the data to refine its hydraulics, sensors and motion software.

Designed to adult human proportions, ARMstrong Dex can operate inside corridors, control rooms, workstations, and other similar places.

Its tracked base can traverse over rough and debris-filled terrain, and its arms are capable of manipulating tools, turning valves, removing rubble, and connecting wires.

Primarily intended for disaster zones and nuclear facilities, it can be operated from a safe distance, allowing human workers to avoid direct exposure to hazardous environments.

According to Interesting Engineering, KAERI has transferred its advanced robot technology to Victex, a company specializing in dismantling nuclear facilities.

With each new milestone, from lifting heavy objects and performing resistance exercises to accurately throwing a half-kilogram bottle, ARMstrong Dex continues to demonstrate the core skills required for effective disaster response: strength, agility, and precision.
