The Mobile Robot can be operated in three different modes, namely Dual Tone Multi Frequency (DTMF), Radio Frequency Input Devices (RFID) and laptop control with ZigBee technique, thereby enabling a multi-dimensional control system. The Mobile Robot is a single seated carrier and can also be used to transport substantial amount of physical load for short distances. It is a prototype of a multi-use robot having a wide range of applicability according to the requirement after suitable modifications. There are four microcontrollers used in this mobile robot. The input to microcontroller sent via the devices like cellphone, RFID and laptop. Thus it can be easily applied inside a hospital to carry patients, as a wheel chair for physically challenged people, to carry goods in large shopping malls, as golf cars, can also be used for industrial purposes with adequate modifications. It uses a DC power source and not any conventional energy sources. Hence it is ecofriendly and this Mobile Robot can be termed as an advancing step in the field of mobile robot.

The gels densified at t150°C show absorption and fluorescence spectra similar to that of melt or CVD prepared Pr-doped silica glasses. Structural properties of the densified gels have also been studied. A1 co-doping increases the fluorescence intensitiy of Pr 3 + ions and shifts the maxima to the shorter wavelength side.
