"SMARTCHAIR" SMARTCHAIR - DEVELOPMENT OF AN AUTONOMOUS NAVIGATION SYSTEM BASED ON IOT TO FACILITATE THE AUTONOMY OF PEOPLE WITH REDUCED MOBILITY DESCRIPTION SMARTCHAIR will investigate the problems associated with a wheelchair system that moves between two points in the environment using a meshed network beacon positioning system (MESH), developed in the IMOLAB project, and that detects and avoids obstacles using environmental recognition techniques (or performs an emergency stop when it is not possible to avoid obstacles). OBJECTIVES The general objective is the development of an autonomous motorized wheelchair system, where the person chooses the destination point and starts the engine to be taken to their destination. The specific objectives are the following. - Development of a control console with a touch screen that serves as an interface between the person and the autonomous wheelchair. - Obstacle detection radar sensors - Wireless telecommunications system based on the mesh network (MESH) of the IMOLAB project. This system allows the autonomous wheelchair to obtain the signal intensity measurement of each beacon that is within the detection range along with its geolocation. An algorithm, which will be developed in this project, will allow three or more beacons to be taken to perform a triangulation of the position of the system to determine its geolocation. The error of this geolocation is expected to be less than the ten meter error of the GPS signal. The use of the electronic map and the obstacle radar sensors will determine the presence of the walls of the indoor area to refine the geolocation of the autonomous wheelchair. - Development of navigation software based on the beacons of the IMOLAB project to determine the route that the autonomous wheelchair must follow to reach its destination. - Development of obstacle classification software to determine if it is possible to avoid them by modifying the trajectory or emergency stop in the event that it is impossible to continue navigating. Development of communication software to send reports about the obstacles found so that the need to send personnel to remove them from the path is determined. Project Number: 22300045 Grant Agreement: IMDEEA / 2023/22 Duration: From 01/06/2023 to 30/11/2024 Coordinated in AIDIMME by: COLINA DE VIVERO, MIGUEL MARIANO R&D Line: PRODUCT DEVELOPMENT AND OPTIMIZATION RESULTS OBTAINED Year 2024: A navigation system has been developed for use within a room by a wheelchair equipped with a Bluetooth transmitter that periodically emits an identification signal that is picked up by Bluetooth receivers connected to a Wi-Fi network and located on the ceiling. Each receiver analyzes the radio characteristics of the received signal, prepares a data packet with the transmitter identifier and the operating parameters that describe the received signal, and sends said data packet via Wi-Fi to the wheelchair controller. The wheelchair controller, using data from at least three receivers that provide coverage, makes a least-squares estimate of the wheelchair's position and thus determines where the wheelchair is in the room. A control console has been developed with a color LCD touch screen that allows the wheelchair user to specify a movement. The user presses a button to start the movement and the chair stops when the movement is complete. The SMARTCHAIR navigation system developed in this research project can be used as a replacement for a GPS navigation system. The GPS navigation system provides a position, but it is not perfect as it can be off by several meters and cannot be used indoors. The SMARTCHAIR navigation system is also not perfect as it can be off by 0,6 meters, but it can be used indoors. As a point of comparison, the best Bluetooth indoor positioning systems on the market can be off by 1,0 meters, so the SMARTCHAIR navigation system is considered to be an improvement over the market offering. A methodology for activating the electric motors of the wheelchair has also been designed, simulating the action of the user's hand to manipulate the element that controls the movement of the wheelchair. Said element that controls the movement of the wheelchair is a joystick. An external accessory to the wheelchair has been designed and built in the form of an electromechanical actuator with two servo motors in quadrature to move the joystick simulating the action of the user's hand. This external accessory allows the manipulation of the joystick as if it were the user's hand without causing alterations to the chair that would invalidate the guarantee. In addition, this external accessory can be removed to return the chair to its original state. The wheelchair controller controls the electromechanical actuator.
