What is UNILEXA?

UNILEXA is a modular exoskeleton platform solution with interchangeable parts that can be added and configured in different ways to suit a wider group of clients. It is an entirely passive mechanical approach, without actuators, sensors, or autonomous control systems. Instead, the system uses the body’s own small shifts in weight and a unique combination of gravity-driven and elastic mechanisms to assist walking, while supporting the user’s body weight. The core system uses a unilateral passive exoskeleton with locked knees and feet always level with the ground. This style of walking is stable in the anterior-posterior direction. In addition, a specialized medial link construction ensures high lateral stability. MEBSTER’s unique system of connected joints ensures more stable and efficient walking.
