My Projects

1) SAMIS : A Smartphone Aided Vein Imaging System

(Intel IRIS National Fair 2016 Grand Award Winner, Intel ISEF 2017 2nd Place Grand Award Winner )

Abstract from Intel ISEF Database :

Vein imaging systems have been used in the medical industry for many years. Most of them work by using the Near Infrared Imaging technique. However, using such a technique made the devices expensive, bulky, and out of the reach of the common people. We explored into low cost implementation of vein imaging on a smartphone and came up with SAMIS, an easily accessible vein imaging solution using an android app.

2) Magniwear : A Wearable Digital Microscope

Digital microscopes are a more modern iteration of a light compound microscope. These microscopes have the advantage of being able to leverage computing power to extend the possibilities of a microscope, like being able to store, share, manipulate or enhance images. They can be less complicated and easier to use and maintain. But most microscopes in existence are not able to cut down on costs, while maintaining reliability, accuracy and connectivity.

Our approach to solving this problem was to build a microscope on top of a smartphone, as a smartphone is relatively cheap. We also made the microscope wearable to extend the limits of a normal digital microscope, whilst also trying to innovate by allowing the microscope to do stuff other microscopes normally wouldn't.

The result of our efforts is Magniwear, a wearable digital microscope, with a low cost, good accuracy, reliability, and tons of other features like voice commands, a binocular view, Image capturing etc. Being wearable allows for hands-free operation allowing users to inspect specimen much more easily. Simplicity in hardware design also improves accessibility, ease of use and lowers maintenance requirements.

2)SynaSpeak : A Low cost Wearable Eye-Blink to Speech Assistive Device for Paraplegics.

Synaspeak is a low cost wearable assistive device for paraplegics which uses electro-encephalographic (EEG) methods to aid them make day to day conversations seamlessly.

3)WalaBreathe : A Wireless Breath to Speech Assistive Device for users

with motor neuron disabilities.

According to the World Health Organisation more than 500,000 people suffer from spinal cord injury each year. It is also noted that and an estimated 20-30% of them show clinically significant signs of depression.

These injuries often disable the motor neuron functions of the people, leaving them in wheelchairs. It also often causes auditory impairment which makes it difficult for them to have day-to-day conversations with their loved one's.

In the last couple of years, a breath to speech based assistive device called 'Talk' was developed. It took breath input from a MEMS microphone and is a wired device .Talk did show how breath could be an interesting area to explore for the further development of assistive devices.

WalaBreathe is a completely wireless breath to speech assistive device that uses Radio Frequency reflectance data from the Walabot Pro to convert a users breath into audible speech.


Maker ( Hobby ) Projects :

Robaldo 2016 (National Level Robot Soccer Challenge Match)

Robaldo was a Robo Soccer Challenge Match organised by PESIT University,Banglore.There where more than 68 bots that took place in the competition from all over india. Our bot was designed from scracth by my friend Chaitanya and myself. The bot was controlled wirelessly using the bluetooth module in an android smartphone as a reciever and an external bluetooth module mounted on the arduino as a transmitter.

We had implemented two advantageous mechanisms while building the robot , the first was design twin grippers in the front and behind the bot. The next mechanism supported this mechanism as it was an Inverse Control Mechanism which allowed the user to control the bot from the Reverse Direction without having the need to turn the robot if the ball was behind the robot.

We battled till the Quarter Finals and made it among the Top 8 strongest bot in the competition. It was truely a fun experiance battleing with other powerful bots that where well crafted.

Below are the images and videos from the Challenge Match , For more videos and images visit :
