Lower extremity exoskeleton walking rehabilitation device UGO220 is a powered gait rehabilitation exoskeleton by RoboCT.


COSMOS is a powered lower limb orthosis, also known as a powered exoskeleton, which enables people with mobility impairments the opportunity to walk independently. Power is provided by sophisticated motors in the knee and hip joints. Combined with advanced sensors and control strategies, the device is designed to allow gait-impaired individuals to stand and walk again.

Who is COSMOS For?

The COSMOS exoskeleton is envisioned to be used in physical rehabilitation centers, homes, and in the community as a mobility assistive device and overground active gait training for gait-impaired individuals. COSMOS is meant to offer people with impaired mobility a new level of independence.

What makes COSMOS unique?

COSMOS is the first powered exoskeleton to be developed in Egypt. It has a modular design and is meant to be donned and doffed quickly because of its five-component design, self-aligning connections, and single-hand adjustment system.

The company reports that the current prototype weighs 14 kg (31 lbs). The exoskeleton is intended to be small enough to be worn while seated in a standard wheelchair.

Ease of Use

The user controls COSMOS by changing their posture and leaning forward to stand and walk, maintaining an upright stance to stop, and leaning backward to sit. There are plans for the production model to include vibratory feedback, LED indicators, and wireless control interface, similar to other exoskeletons of its class.


COSMOS’s Android app allows control of motion strategies and modes; it also will enable control over gait parameters such as stride length, step frequency, and step height and record walking data so users can track their progress.

Cosmos Bionics has a growing YouTube channel (link) with more use cases and information regarding its medical exoskeleton project.
