Abstract: Navigation of mobile robots in unknown environments is one of the most research areas. Mobile robot can be used in many applications such as indoor and outdoor security patrols, material transport.The Collision avoidance implementation will take advantage of embedded system implementations based on the Renesas microcontroller, RL78/G13, with interactivity to an wireless communication technology called ZigBee technology which will be responsible for assisting the robots in avoiding objects in its path of motion. The proposed project takes advantage of the emerging Radio Frequency Identification (RFID) technology to guide the robot to navigate in its working space. The main advantage of this project is, since Zigbee is bi-directional wireless communication technology provides data integrity check and authentication. Transmitting and receiving information has lower power consumption.
Keywords: Renesas microcontroller, IR and PIR sensors.
