Embedded system applied to obstacles detection in a mobile controlled by a PC via RF

In this work it is demonstrated the operation of an embedded system applied to a mobile robotic system, whose control is based on the development board SPARTAN 3E. The robotic system receives information from the external environment by applying ultrasonic sensors as a means to detect objects around a mobile. A prototype electronic system that allows a mobile robot to detect obstacles in its environment and to know the distance to which is such an obstacle which is shown in an LCD is presented. The system use three sensors placed on the mobile. As a first stage, the mobile is controlled by a computer via RF.
