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. | Journal of Automation and Control Engineering Vol. 6, No. 2, December 2018 Redundant Mobility System Design for Impaired People Mauricio Plaza Torres Universidad Militar Nueva Granada, Bogotá, Colombia Email: The project system was design with a microcontroller to assist in controlling the motion of a wheelchair and a home automation system using head movements for people with disabilities. With this system, the person with movement limitation can control the displacement and the comfort on a specific area. [1] The system can assist quadriplegic handicapped people with limitation on arm and leg movement to steer an automated wheelchair and home automation system. [2] The system includes a head position recognition technique based on infrared sensor with redundant pressure system. The sensor device sends the signal to a computer system that processes the information, include redundant information from the software to avoid mistake for incorrect order o reading information. The system measures orientation angles and send a signal of converted position into adequate steering commands. Additionally, the system has a software verification system to avoid damage or movement problems in specific areas. The system can be used with several types of standard electrical powered wheelchairs. We introduce a different approach for head control for electric wheelchairs. The signals are received and converted into proportional signals that control the wheelchair position and speed. Sensors are used to monitor the changes due to the intentional head motions of the patient and deduce the order to control de Wheelchair with approve of the control software that monitor the trajectory and take an additional decision to follow a correct trajectory. The software interface control generates signals connected to the interface to control wheelchair with minimum head movement. [3] After the software design was finished, all users where adapted to the .
