Active Contact Physiotherapy System

It is easy for human body to contact with objects for a long time to cause fatigue of corresponding parts. How to use robot technology to reduce or eliminate this fatigue in order to improve work efficiency, ensure human health and improve comfort is an important problem in the field of robot. In this paper, combined with the characteristics of animal tissues (puffer’s air bag, etc.), through the application of soft robot related technology, a set of program-controlled active flexible massage system is made. The system is mainly composed of support frame, air bag placement module and electrical system. The system can be freely deformed and combined, soft and comfortable, and has strong expansibility. In addition, we propose a control method to calculate the relationship between the air pressure inside the airbag and the surface tension of the airbag, set four working modes for the system, and measure the air pressure inside the airbag under the four modes. The results show that the proposed control method is feasible and will have a very broad application prospect in medical rehabilitation.
