Introduction
Robots have been used all over the world. A role for a new generation of robots is eagerly awaited. In order to improve society in general, types of robots are being introduced. As new trends in the modern world evolve, robots begin to make
their presence felt. Robotic vacuum cleaners [1], ladder-climbing robots [2], and robots for the blind [3], etc., have already been created. Currently, various robotic vacuum cleaners have been presented; however, they have focused on ground cleaning and lack an interactivity between the robot and the user. One such robot, roomba, created by iRobot for ground cleaning, cleans by expanding the vacuuming area with a screw path, recodes the path coordinates, and then sweeps the non-cleaned area. Soon, though, the robots path is blocked and a new vacuuming area is required, hence an interactive user becomes crucial. In order to improve interactivity between robot and user, an intelligent robot in conjunction with a wireless internet has been developed.
By using a wireless series transport model (802.11b), not only can the vacuuming function be performed automatically, but the path can also be recorded and shown on the monitoring system; additionally, by manipulating the moving command, the robot can efficiently clean up the entire area.To reach our proposed goal, the selection of an appropriate high sensitivity sensor is essential. Versatile sensors such as a camera catch device (CCD) [4, 5] used for path-guiding in an unknown environment have been addressed. Moreover, a moveable ultrasonic detector [6] used in avoiding obstacles is also discussed. Thus, a robotic vacuum cleaner equipped with an ultrasonic sensor and a wireless network is proposed.
