Introduction
4 types of robots are being introduced.
As new trends in the modern world evolve, robots begin to make
6 their presence felt. Robotic vacuum cleaners [1], ladder-climbing robots [2], and robots for the blind [3], etc., have already been created. Currently, 8 various robotic vacuum cleaners have been presented; however, they have focused on ground cleaning and lack an interactivity between the robot 10 and the user. One such robot, roomba, created by iRobot for ground cleaning, cleans by expanding the vacuuming area with a screw path, 12 recodes the path coordinates, and then sweeps the non-cleaned area. Soon, though, the robots path is blocked and a new vacuuming area is 14 required, hence an interactive user becomes crucial. In order to improve interactivity between robot and user, an intelligent robot in conjunction
16 with a wireless internet has been developed.
By using a wireless series transport model (802.11b), not only can
18 the vacuuming function be performed automatically, but the path can also be recorded and shown on the monitoring system; additionally, by 20 manipulating the moving command, the robot can efficiently clean up the
entire area.
22 To reach our proposed goal, the selection of an appropriate high
sensitivity sensor is essential. Versatile sensors such as a camera catch device 24 (CCD) [4, 5] used for path-guiding in an unknown environment have been addressed. Moreover, a moveable ultrasonic detector [6] used in avoiding 26 obstacles is also discussed. Thus, a robotic vacuum cleaner equipped with
an ultrasonic sensor and a wireless network is proposed.
