Research Abstract |
This project is a fundamental research on cooperation among multiple distributed autonomous mobile robots. The purpose is to develop cooperative control algorithms, sensor systems and several prototypes of mobile robot and mobile manipulator and to demonstrate the availability of developed systems by experiments. The basic concept of intelligent distributed autonomous robot system has been discussed and experiments by newly developed robots have been done by researchers at both University of Electro-Communications and Griffith University. The results obtained are as follows. 1) Several methods of obstacle detection and obstacle avoidance have been developed by using characteristics of multiple infrared sensor and ultrasonic sensor cooperatively. 2) As a case study, cooperation among multiple autonomous robots in intelligent vehicles and trans-portation systems is considered. Algorithm for road intersection crossing, front-vehicle tracking, overtaking, lane following, obstacle avoidance,

front-vehicle distance control, narrow bridge crossing and formation driving have been developed and implemented to the robot system. 3) A new method, that is, rapid obstacle sensing using mobile robot sonar (ROSUM), for treating the crosstalk data of a so-called sonar ring, while employing a simultaneous firing regime has been proposed. It is shown by experiments that the robot with ROSUM sonar ring can avoide obstacles quickly and smoothly in complicated environment. 4) A new prototype of mobile manipulator with exchangeable active/passive joints has been developed in order to solve various problems in performing a cooperated task, in which a long pipe is to be moved out from a restrained location, transferred to an assigned position and set to a new restrained location. Experiments on proposed task by the cooperation of human and the mobile manipulator have been performed. The task was performed successfully by the simple control method. Cooperation for the task by two mobile manipulators will be done in the next work. Less
