Angel Robotics turns its walking suit into phai-x1, a research platform for physical-AI labs that logs muscle and ground-force data

KOSDAQ-listed Angel Robotics has launched phai-x1, a wearable robot built for physical-AI and biomechanics research, Korean daily Edaily reported on Sept 29, citing the company; the report is linked from Angel's own newsroom.

The platform is based on the company's Angel Suit H10 walking-assist robot, controls the left and right hip joints independently, runs researchers' own control algorithms at 1,000 Hz through an expansion module, and records joint and state data alongside optional IMU, electromyography (EMG) and ground-reaction-force sensors, so human movement and robot response can be used together as AI training data.

According to the company, phai-x1 served as the platform for the IFAC Wearable Robot Challenge 2026 in August, where participants implemented algorithms such as uneven-ground walking control, slip detection and support for hemiplegic walkers after about two hours of training.

Angel plans to sell it to universities, public institutes, corporate labs and hospital research groups, together with training programmes and joint research; no price was given. Founder Kong Kyung-chul, now head of the company's future technology institute, said cameras alone are not enough for AI to understand human movement.

The launch fits the pattern in MEKAWIRE's comparison of Korean wearable makers published on Oct 16: WIRobotics is moving into humanoids with its Mobile ALLEX research platform, and Angel is now selling its own hardware as a physical-AI data tool.
