Archelis Inc. is a startup company that spun-off from Nitto Co., Ltd. in February 2020. Nitto is a large manufacturing company with a history of 53 years, capable of everything from development to trial production and mass production, and we are an exoskeleton service company that inherited those technologies. Our product "Archelis" is an innovative passive exoskeleton that reduces the burden of prolonged standing works. This product was originally developed for physicians who stand and operate for long hours. By distributing and supporting the weight with the shin and thigh, the body becomes stabilized, and the burden from standing work is greatly reduced. Despite being developed with medical use in mind, Archelis has great potential in a variety of fields, including factory workers, security guards, farmers, and cooks, etc.
