Abstract
This paper proposes the mechanical design and the trajectory control of a mobile robotic system applied to the displacement of the visually impaired in physical facilities IFPE Caruaru. The movement of the automatically guided systems is based on the study of the different techniques of generation of existing paths and methods of evasion of obstacles, which use different types of algorithms for the control as part of the system of direction and navigation of the system. The idealization of the system involves designing roadmaps, paths and determination of the following trajectories, which depend somewhat on the configuration of the machine. The study of the different configurations for the paths planning should consider a previous knowledge of the physical plan of the layout in simple line. Among the specific objectives, it is intended to select a suitable microcontroller for application, as well as to assemble the embedded system (microcontroller system and power circuits for direct current motors), to study and select among the orientation methods, the most suitable for applicability , to program in C language an efficient firmware, so that the microcontroller can execute the PID control of speed, generation of paths and obstacle avoidance, and finally devising a destination choice with man-machine interface through application voice command on Smartphone. For cost savings and applicability of independent electromechanical structure, the mechanism control is set in the application, and the embedded system will only be the receiver and executor of control signals through Bluetooth communication.
