This paper presents the results of a research work carried out in the Elect
ronics Department of the University of Alcala in the field of electronic sy
stems for the guidance of wheelchairs for the disabled and/or the elderly.
These electronic systems have been designed to meet a wide range of needs e
xperienced by users of this type of wheelchair. One of their most important
features is their modularity, thereby making them adaptable to the particu
lar needs of each user according to the type and degree of handicap involve
d. The overall system includes a complete user-machine interface, motor con
trol modules and safety and autonomous guidance systems. The project is cal
led: "Sistema Integral de Ayuda a la Movilidad (SIAMO)" (integral system fo
r assisted mobility). (C) 2000 Elsevier Science Inc. All rights reserved.
