ANGEL LEGS M20-A and M20-B are medical devices for rehabilitation treatment.​
While they incorporate the same key technologies as other products, these devices offer enhanced user convenience,
particularly in the context of a hospital environment. They are designed for quick donning and doffing,
well-suited to domestic rehabilitation settings. Users can maximize their rehabilitation sessions,
utilizing over 90% of the allocated time, a significant advantage in real medical scenarios.

ANGEL LEGS M20 is an exoskeleton walking assistance robot that operates on the ground.
It serves as a gait rehabilitation training robot, aiding in the recovery and treatment of muscle and motor functions.
When a patient with incomplete paraplegia attempts to walk, it identifies the intention to walk, calculates,
and provides the necessary force assistance to support the wearer in gait rehabilitation training.
