A sprocket transmission mechanism of a massage device contains: a driven box, a pair of hollow holders, and two bendable chains. The driven box is driven by two drive shafts of a motor beside the driven box. The pair of hollow holders are rotatably connected with the two drive shafts respectively and have two grooves, and the pair of hollow holders are connected inside two inner sides of a chair or a bed respectively. The two bendable chains are accommodated in the two grooves individually. The two drive shafts have four sprockets fitted on two sides thereof individually, and two driven sprockets are rotatably connected between the two sides of the two shafts respectively, such that the two bendable chains are inserted into the pair of hollow holders to mesh with and to drive the four sprockets and the two driven sprockets to rotate individually.

A communication robot for operating a massage providing apparatus by executing an artificial intelligence algorithm (AI) and/or machine learning algorithm in a 5G environment connected for the Internet of things and a method for operating the communication robot are provided. The method for operating the communication robot may include acquiring a spoken utterance of a user positioned within a prescribed range from the massage providing apparatus, tracking a spoken utterance direction of the user from the spoken utterance of the user, orienting the communication robot towards the spoken utterance direction of the user, acquiring a voice command included in the spoken utterance in relation to operation of the massage providing apparatus, and operating the massage providing apparatus according to the voice command.

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.

A suit type exoskeleton adjustable to a user's body size includes a wire, a wearing portion worn on a part of the user's body to assist with physical strength, a controller removably coupled to an outer surface of the wearing portion and coupled to an end of the wire, and a driver coupled to an opposite end of the wire and configured to provide power to the wire. A suit type exoskeleton for knee power assistance is characterized by use of the suit type exoskeleton which is adjustable to a user's body size for their knee.

A massage providing apparatus operated by executing an artificial intelligence algorithm and/or machine learning algorithm in a 5G environment connected for the Interne of things and a method for controlling the massage providing apparatus. A method for controlling a massage providing apparatus which may include acquiring information related to image content from an image content playback device for playing back arbitrary image content, analyzing the information related to the image content, setting a massage mode according to a result of analyzing the information related to the image content, and controlling the massage providing apparatus to operate according to the set massage mode.
