HMH (www.hmhis.com) specializes in developing and manufacturing a wide range of products using the mechanisms in hospitals and healthcare fields, including their blister automated dispensing systems, rehabilitation robots, and automatic powder dispensing systems.

HMH’s exoskeleton-control type training rehabilitation robot, Exowalk, is paired with a wheelchair and is based on the design/control of a lower limb rehabilitation robot so that a severely disabled person can use it. Refined to an even greater extent, the new product is manufactured using only Korean technology. This product was commercialized after passing safety evaluations from authorized agencies; medical device certification from the Ministry of Food and Drug Safety; and clinical trials and usability evaluation based on real users.

The product can boast stability, mobility, cost-effectiveness, space efficiency, and low noise technologies.

Exowalk is an exoskeletal robot walking system, which, unlike current robotic walking training systems that can only walk in place, actually allows the patient to move forward during their training. Actual walking training motivates the user and instills confidence. It is possible to do a lot of walking (more than 600 steps/30 minutes) in a given time.

Depending on the intensity of the rehabilitation training, the driving wheel can be set to a level of 1-10, according to the walking speed and stride of the patient.
Forward, backward, left and right directions are all possible. The built-in lead/lithium ion rechargeable battery allows prolonged use, and the cost is roughly ¼ of the cost of exoskeleton gait training robots currently on the market, making it an attractive cost-effective alternative. A wireless controller allows the therapist to effectively train the patient, thereby minimizing the therapist’s need to physically manoeuvre the patient. In addition, the system generates very little noise during training, giving patients a stress-free environment; putting on and taking off the robot requires little time.

The Walkbot weighs about 180kg and 4 degrees of freedom (DOF) are possible. The product’s dimensions are 1333 (L) * 750 (W) * 1350 mm (H).
