ABSTRACT

Introduction: The requirement for movement of heavy loads in certain professional works has brought about the advancement in transportation devices with the objective of preventing temporary pains and lesions that may last a few hours or permanent injure to bone and muscle tissues. This situation is more common in the military personnel since field activities normally require the movement of equipment to long distances and this often exceeds the soldiers´ strength limits.
Objectives: To show and to develop a design of back system for the passive lower limb for militaries, repetitive activities and people with muscle tension problems, in order to solve some present technical problems.
Methods: New biomechanical technologies were used such as the measurement of the research intention to design a backing system. The process of design was addressed through the search for optimization and improvement of the physical and functional characteristics of the prototype to assure that the prototype offers the expected protection and support.
Results: The detection system was used to determine the user´s intention and to achieve an adequate functional design of the device. The designed exoskeletons are portable and autonomous in their mechanical parts, thus improving the present limitations associated to portable devices.
Conclusions: The final design is an exoskeleton that allows a healthy person and people with mobility problems in his muscle-skeletal system to use the device for a better energy consumption and for more effective and less consuming movements. The design included psychological information, biometrics, specification of biomechanics and low cost design.
