CHANDIGARH(TIP): Rohan Arora and Pulin Aggarwal, the students of Electronics and communication Engineering department of UIET ( University Institute of Engineering and Technology ) of world renowned Panjab University, Chandigarh have devised a cheap video based robot under the guidance of their Assistant Professor Sarvjit Singh. This device can be utilized for the surveillance of homes. Assistant Professor Sarvjit Singh said that the cost of developing this device was about Rs 6800/- ( US $ 113 approx) and it can be connected to LAN through laptop or computer for video. It can be modified to connect it with WAN or internet. This wireless surveillance system can be moved in different directions through a remote control device. In this context, Professor Sarvjit Singh added that surveillance systems available in the market are quite costly, ranging between Rs30000/- (US $ 500 approx) to Rs40000/- (US $670 approx). Their device is affordable and it keeps watch over the house in the absence of its master, once it is connected to the internet. Besides, it can be used through mobile application. “Since it has a higher torque which enables it to get through a surface like muddy waters very easily,” claimed Assistant Professor Sarvjit Singh. According to him, this device can be further improved with better technology. Presently, their priority was to develop an inexpensive device. Had they made its chassis at their own, it would have cost even less. Also, the data it sends at present is just password protected but can be encrypted for use in army, for example. This project was completed in time span of 5 months. Assistant Professor Sarvjit Singh said that these students had earlier won an award for their autonomous surface monitoring robot.
Two students- Oshin Garg and Saurabh Singh- of ECE (Electronics & Communication Engineering) branch of UIET (University Institute of Engineering and Technology) department of world renowned Panjab University Chandigarh have developed a low-cost desktop Braille printer for blind persons under the guidance of their Assistant Professor Sarvjit Singh. The creators of this device said that common Braille printer available in the market is very costly as its price ranges between Rs 25000/- (US $ 415 approx) to Rs 30000/- (US $ 500 approx). As such, it was sort of challenge for them to develop a low cost Braille printer costing between Rs5000/- (US $85 approx) to Rs10000/- (US $ 170 approx).
There is a scope for further reduction in cost. This project was completed in time period of 5 months. This printer is ATmega 16 microcontroller based. It has a needle which moves with a motor to perforate a sheet of paper. This device runs on a 12 V adapter and the consumption of electricity is even less than that of 25 Watt CFL.
