Description

WIM S is a consumer exoskeleton designed for walking and exercise. Its main unit sits at the front of the waist, with a frame and straps connecting it to both legs. A single motor generates assistive or resistive torque, while the control system responds to the wearer’s movement.

The WIM S integrates its battery into the main unit and has a manufacturer-stated IP65 protection rating. The wearable system weighs approximately 1.6 kg (3.5 lb). It folds for transport and uses adjustable waist and leg attachments. It includes Air mode for ordinary walking assistance, Aqua mode for added resistance during walking exercise, Care mode for slower walking and shorter strides, and Hiking mode for slopes and stairs. Rest mode stops torque generation. Available modes can vary by model. Note that Aqua refers to resistance training, not underwater use.

The companion app connects via Bluetooth to record walking activity, display gait information, and adjust exercise settings. WIM-UP offers guided walking exercise programs. WIRobotics identifies WIM S as a walking and exercise product, not a medical device or a product intended for therapeutic use. WIM S succeeds the original WIM.

Additional information:

WIM S supports both assisted walking and resistance exercise, allowing users to alternate between the two for interval training. Aqua mode adds adjustable resistance to increase the effort required to walk. This mode also recovers energy during exercise. Hiking mode assists when climbing ramps or stairs and supports controlled movement during descents, aiming to reduce impact when walking downhill.

The companion WIM app tracks walking activity over time and provides feedback on gait characteristics, including speed, balance, and posture. Its analysis includes a gait score and estimated “gait age,” manufacturer-generated indicators intended to help users monitor changes in their walking performance. The app also provides personalized exercise suggestions based on the wearer’s gait data.

For everyday use, the WIM S is meant to be put on or taken off in approximately 30 seconds.
