Abstract—Mobility is important factor for a good quality of life. Injury on back spine produce loss of self-mobility and need of additional help from other people include the family members or medical nurse staff. The aim of the project is a design a system for provide independent mobility for disabled people. The final system would be a design for a Handicapped person with spinal cord injury those who could not move their hands as well as legs, with a new human-machine interface for controlling a wheelchair by head movements. It is a good alternative to self-movement when other parts of the body have mobility problems. It has been found that this project can be used by not only the Quadriplegics, but also by all those who are mobility impaired. Quadriplegics are limited in lower and upper member movement and need a specific device to communicate with a system like wheel chair for mobility without assistance. Design mechanism for quadriplegics to provide movement in a specific biomechanical area and independence is the main goal of the project. The system is a following head tilt movement that produces a signal for control a wheelchair that could operate in any direction using head movements. This system is complemented with movement intention sensor software. The software read the intention and matches the order to double check the movement order. Additional to this software, the system has a program to help the person to follow a specific trajectory and the control of the position to avoid injury for a mismatch order.
