As the technology is growing day by day the best way to connect with each other in the today's world from the different areas of the various country is video conference.

GNU Radio is used to work on the different modules. The Real-time Video signal will be transferred and receive by the GMSK Modulator and Demodulator.

Equipments: Webcam ,Two PC with GNU Radio and GStreamer, One USRP for Transmitter And One for Receiver.

    Block Diagram

    Final Outcome

Successfully able to send a video from one device to another

device using USRP. But, there is different way of transmission of real-time video.

Our main focus is on the transmission of video source using a GMSK modulation scheme.

The encoding and decoding of the real-time video can be done significantly with the minimal loss of data by using the H.264 encoder and H.264 decoder.

In conclusion, SDR system provides flexibility to development of video transmission using GNU Radio software and USRP hardware.

    Future Work

In future we will be working on transmitting a live video using USRP. For that identification of what changes are need to be done in the H264 encoder and decoder are to be found out.

2) Stair Climber - SHIN UP

    Abstract

Material transferring on a flat floor or on stairs has been one of the major issues faced by the society when it comes to transferring heavy machines or equipment from one storey to another storey. Shin-Up is a stair-climber which can lift weight upto 400 kgs and can balance the load on it’s base and will climb stair automatically or manually

    Actual Image

    Final Outcome

The machine requires single human operator in order to control it in manual mode which reduces the man-power. The automatic mode assures the load safety as it senses the amount of inclination of stair and balances the load.

Timing belt and pulley mechanism makes the escalation of the machine slip resistant.

    Future Work

Sensing of an obstacle in the path of the stair-climber can be accomplished in future by working on it using artificial intelligence.

Reduction of the dead weight of the machine by using more efficient and less heavy materials by replacing mild steel can also be accomplished in future.

3) Spring Based Universal Testing Machine

    Abstract

 Tensile testing is an engineering test in which the test piece is subjected to incremental and controlled tension until failure. Few properties that can be measured via the test are ultimate tensile strength, breaking strength, maximum elongation, and reduction in area. It’s necessary to test tensile strength of material chosen before actual use in a build.

    Block Diagram

    Inspiration

  • Focus: Educational Institutions

• Universal Tensile Testing machines (UTM) are bulky and require electromechanical components to give accurate test outcomes

• Results in expensive machinery - not justifiable in an educational institution

  •  Focus: Commercial Avenues

• Target sector: Micro, Small & Medium Enterprises (MSME)

• Manufacturing Sector MSME is 7.04% of total GDP

• Problem here is the cost(Commercial ~ ₹ 6 Lakh) - unaffordable for MSME

    Future Work

Testing on other test pieces with different material composition and processes to get an accurate representation of the machine performance

More robust force calculation methods can be used to accurately calculate the stress acting on the test piece

New fixtures to measure other parameters such as flexture, compressive strength,etc.

Possibility of automating the force applying mechanism for future iterations

14) Easy Shop

    Abstract

We have created a system where the buyer can easily access the details of any product available in the mart with least possible human interaction

We have used RFID tags/labels on every product that will store all the information of certain product. NFC is used to transfer information to user from RFID tags/labels.

We also have used RFID reader to scan all the products and generate bill which will be send to the user’s mobile phone via HC-05 Bluetooth module that links Arduino and mobile phone.

    Block Diagram

    Final Outcome

 

After the integration of parts, the user will be able to view details of each and every item and add them to his/her virtual cart as well as a physical trolley which has a unique ID.

The main reason to add them to a virtual cart is to generate a bill. At the check out the trolley will pass through a security check where an RFID reader would read all the tags of the products inside the trolley at once and compare them with the virtual cart.

Thus the user wouldn’t have to wait in a long queue and after the check he would easily get the bill on his mobile phone with the help of Bluetooth transfer from arduino to mobile.

We have made this project in the Hackathon held at Ingenium '18 and have won the first prize in the IoT department.

16) NEWGEN-ExFAT

    Abstract

File systems are important in an OS for user to work. Earlier FAT file systems were used which had limitations of memory management. The largest file size can be up to 2GB.

Newly the NTFS is used in windows now a days which has quite faster and has very large memory support.

    Final Outcome

A non-hierarchical implementation of ExFAT file system is done. The implementation has the main data structures of ExFAT(Boot sector, Bitmap tables, etc.) required by an OS along with the basic functionality of a file system.

Functionalities include creating a file, reading a file, and deleting a file. Also, a cluster can be read or reset.

    Future Work

The system can be made hierarchical so that folders and files can be created. The interface can be made more like a command line application.

More attributes can be saved to make it more sophisticated.

17) Paperless Attendance

    Abstract

Currently at AU we take attendance by either passing an attendance sheet or in some cases professors directly mark it on Auris. While in the first case a very large amount of paper is consumed in the second case professors have to sacrifice 10-15 minutes of their lecture. By rough estimation 672 sheets are used only in SEAS yearly.

In addition to this proxy filling and tedious job of updating the attendance periodically on AURIS are some of the issues.

To address the above problems an idea of paperless attendance where the main focus is on reducing the consumption of paper and in addition save valuable time of the faculty, free the faculty or the TA from the responsibility of updating attendance on AURIS and reducing proxy filling.

    Final Outcome

Paper used for taking attendance is completely eliminated. An A4 size paper takes 10L water and saving 672 sheets per year is equivalent to saving 6720L of water, which is a huge amount!

Paper used for taking attendance is completely eliminated. An A4 size paper takes 10L water and saving 672 sheets per year is equivalent to saving 6720L of water, which is a huge amount!

The entire process is such that it leaves a very minimal scope of discrepancies.

    Future Work

We have used beacons for location verification in this project and the same can be used in various other projects to make the university more interactive, for example :

  • Routine or occasional updates based on user’s location
  • Location tracking of user in emergency situations
  • Aid faculty in grading students based on their interaction in class

By controlling both the X and Y- axes motors at the same time we can achieve capability of generating curves. More accuracy can be achieved by using metal pulleys.

18) Smart Parking System

    Abstract

Availability of parking spaces and looking for it is a major issue now a days. Traffic would be reduced a lot, if the drivers are directed to the parking spot instantly.

Also, instead of Parking Fee and E-Challans (which are irregular, irresponsible and delayed), introducing this system having auto-deduction of fine (if applied) would be helpful to the government.

    Block Diagram

    Final Outcome

 

Parking issues and Fine Issues would be easily solved. It directs the driver to a proper/empty parking position on road accurately.

Also it deducts the parking fee, check for wrong parking, alert the user about it and deducts fine (in that case). It automates the fine procedure.

    Future Work

Make use of RFID Tags at any one corner of the vehicle, to make the detection and deduction of fines easy, efficient and safe. Could use better sensors with high functionality to get exact real time values.

Make an official website by approval of govt. for real time tracking through Google Maps of parking spaces for ease of drivers.
