Anveshan 2016 Winners
Project: IoT based Virtual Physiotherapy with Biofeedback
Team Members: Renganathan B S, Dhinesh R, Payal Mohapatra, Payal Mohapatra
Summary: Remote patient monitoring can be targeted at different classes of patients and one of them happen to be for patients rehabilitating from surgery, accidents etc. The proposed solution for them is an IOT based virtual physiotherapy and movement assessment system that enables physiotherapists in providing effective care virtually anywhere. The patient's movement is assessed through a system which includes a body sensor network and RGBD camera. The camera also provides a live video feed of the patient's movement to the physiotherapist. Wireless sensor nodes with Inertial Measurement Unit will be placed at various locations on the body to map the motion in real time. This can give a number of parameters [e.g., joint angle] for the physiotherapy to assessment of the patient's progress in his recovery. This system can also measure physiological parameters like heart rate to assess the strain endured by the patient during the exercises and in providing feedback for finding out the optimal level and intensity of the exercises without under straining or over straining the patient. Our framework includes an interactive 3D game for the patient to play which helps the patient feel motivated and also providing the necessary information over the cloud for the physiotherapist to monitor the patient's progress from anywhere. In a country like India with a skewed ratio of medical practitioners, caregivers to patients and medical help seekers, this system could be of use for providing affordable healthcare at scale.

Project: Low cost visual sensor node for surveillance applications
Team Members: Abhinandan Jain, Shailendra Kumar
Summary: The problem related to wireless visual sensor network applied for possible applications such as habitat monitoring, border patrol, battlefield surveillance, agricultural monitoring, traffic monitoring, smart city network and so on where images have to be transmitted over a wireless medium is limited bandwidth, energy, on chip computational power and memory. The sensor nodes generally have a processor unit of low complexity with restricted power and random access memory within a variation of 10KB. The algorithms needed to transform and encode the images are computationally complicated and have high requirements as compared to the low power sensor nodes.
The proposed solution is based on low cost visual node which efficiently compresses the image with some loss in quality and transmits it wirelessly over the internet. The low bit rate image compression algorithm is specifically designed for resource constraint low power sensors hence saving both the bandwidth and power of the node. The applications of the portable node range from surveillance applications in remote areas to medical imaging, employing features like Image on Demand or Video on Demand over low bandwidth network.
Project: Smart Garbage Monitoring system
Team Members: Mandava Chetan Chowdary, Thotakura Anirudh, Thotakura Anirudh, Vedula Ravi Teja, Chidepudi Sivarama Krishna Reddy
Summary: The Smart cities mission is an innovative and new initiative by the Government of India to drive economic growth and improve the quality of life of people by enabling local development and harnessing technology as a means to create smart outcomes for citizens. And these cities has garbage management as one its main challenge.
The existing system of garbage management involves foul smell, overflow of garbage containers, and accessibility by animals, birds, and unwanted visits by sanitary trucks even if the containers are not filled. These problems are addressed in the Smart Garbage Monitoring System.
In the proposed smart system, the garbage container is kept underground whose garbage levels can be monitored online. As the trash in the container reaches its threshold value the sanitary truck driver can see it online. When the truck driver reaches the container's location, he can authorize the underground system which will then lift up to ground level. The container can now be emptied and placed back which will again go underground, thus solving the problem.
EXPERIENCE OF WORKING WITH ANALOG DEVICES
1st Prize Winners: IoT based Virtual Physiotherapy with Biofeedback
Anveshan is a very enriching platform for budding engineering enthusiasts. This competition provided the feasibility of bringing into life a prospective project (eventually product) we had in our minds from sometime. The main advantage of competing in such competition is we can have direct interaction with the industry. In this regard, we were fortunate enough to have a mentor directly from ADI. This helped us to understand how the projects are run other than in the professional settings. We also learnt to meet the deadlines set for the project and to tackle the unexpected problems which one faces during the project development. We generally work on individual projects which often has very little team work as part of our coursework. But Anveshan gave us an opportunity to work together as a team. This platform helped us become a good team player and to resolve conflicts that arise during the execution of the project. Periodic presentations helped us interact with ADI officials and broaden our horizons to the real-world feasibility and applicability of our developed prototype. Being from an academic background the setting was really enlightening to us. ITD also provided a good platform to show your prototypes and get expert feedback to improvise from the industry veterans. Overall it was great learning experience and a fun filled journey.
2nd Prize Winners: -: Smarter Air
Our team expresses our happiness and gratitude for the extraordinary support we were provided throughout Anveshan. We feel proud to have been part of Anveshan. Our HoD expressed her regards as well!
3rd Prize Winners: Low cost visual sensor node for surveillance applications
ADi has provided us unique opportunity to implement an d test our in-house developed image compression algorithm on BLIP platform. Transferring an algorithm from its theoretical testing to its practical hardware implementation was a great experience for us. The practical experience gain has boosted our confidence and brushed our skills which will help us to achieve in our future endeavors. During this challenge the critical inputs from the ADI experts has helped us improve our design and application addressability. We would like to acknowledge the financial support and evaluation boards supplied from Analog Devices.
3rd Prize Winners: Smart Garbage Monitoring system
First of all, our team is thankful to our college mentor Dr. Philemon Daniel (Asst. Prof. NIT Hamirpur) who encouraged us to participate in "Anveshan 2016 IoT Fellowship" and for being with us throughout the project.
When we came to know about it, we went through the Anveshan Portal and got to know about the rules and areas on which the projects should be concentrated on like Health, Agriculture, Smart Cities etc... We started to search for the existing problems in the current system in these areas. This step helped us to think towards social problems and we spotted one big issue along way. That is 'Open Garbage Bins' in the cities. Few days later we came up with a solution of implementing an "Underground Garbage Monitoring System with sensors integrated to the internet". We made the proposal document adding the abstract, mechanism and the future scope of the project in Smart India.
At the end of July we received a call from Analog Devices India(ADI) enquiring the feasibility of our project and how we were going to implement it. It was an important stage for our project to get through the competition. The next day we received an email from ADI saying our project is one among the selected ones for Anveshan 2016-17. We were assigned to Mr. Anand Venkitasubramani and Mr. Narsimh Kamath as our mentors from Analog Devices. We had our first Skype meeting on 19th August where we discussed about the project and ways to develop a working prototype out of the idea. Our mentors keep on giving valuable inputs in the subsequent meetings and suggested us to go through different Analog Devices microcontrollers which would be best suited for our prototype and advised to get connected with the engineer zone(EZ) of Analog Devices.
In the course of time we found ADuCM3029 which was the first microcontroller developed by Analog Devices for Internet of Things(IoT) applications. After figuring out the microcontroller, our prototype was in need of a best communication protocol for IoT and we decided to go with 6LoWPAN technology after discussion with the mentors. We ordered all our Analog Devices modules and sensors and received them by the end of November. Meanwhile we ordered all the other non ADI components as well. We started to work on the Electronics part of the prototype in December during our winter break.
As the microcontroller ADuCM3209 was newly released, there was no adequate content on the internet related to it for our reference. Fortunately Mr. Narsimh Kamath is working on the same microcontroller and he suggested us some good ways to code. The coding for this microcontroller improved our skills in "C". We started to post questions in engineer zone and received some fruitful suggestions. One of the major problem in our project was of the lifting mechanism and our mentors suggested to use Hydraulic lifting which will be feasible.
ITD 2017 is really a good platform to get different views from tech giants of Analog Devices. We noted the suggestions we got in the ITD '17 in which we can develop our project and worked on them.
For the final demonstration we had a full-fledged developed prototype representing our idea. Instead of rushing the project, we worked on it till we were satisfied about every single part of it. Our mentors boosted up our confidence for the final viva in all possible ways and suggested us some important points to concentrate on. We hoped for the best after the final Viva and Presentation at ADI's office in Bangalore.
