The basis of this paper is to design and development of portable system for stress free walking and sitting. basically this modular and portable system is a electromechanical system which will help old or aged people and disabled people to walk freely without applying excess stress on their bones, that is this system helps in reduction of stress on legs while walking, also this will help them to walk with more speed than regular. It is also designed for purpose of sitting anywhere with

... structure by just taking support of the wall and without use of chair. This is a modular electromechanical system which is attached externally to legs on outer sides of both feet that means this electromechanical structure is detachable from the body. And the mechanical structure is made in such a way that it will support the back also because at the time of sitting, support to back is required. The design consists of number of simple DC motors of particular specifications, Microcontroller or Microprocessor, mechanical linkages, and other basic mechanical and electronic components. This design can be made in very cheap cost and also portable so that we can take this structure anywhere in car or through any transportation medium and use it, also it utilizes very less space when made at potable condition.
