Till recently, holograms were of the distant future and belonged to popular forms of fictional media. With the rapid advancement of technology, holograms have become something that is no longer out of the reach with a little effort. This project was born out of the desire to produce a simple technology to help holograms be accessible to anyone for their needs. “For example, when taking a class on biology, a 3D hologram of machinery would provide students with a better understanding than referring to a simple diagram”, says Harini.

The image will be recorded on a film and when a laser light is passed through a film. The 3D image present on the film will be projected in space. If the light is passed from the bottom, the image will be projected on the rear view screen placed in front of it. A pyramid-like structure will be placed on top of the rear view screen such that the pyramid will have 4 sides of 45 degrees each. The screen will have an image which is to be projected on all four sides of the screen. The image on the rear screen will be projected on the pyramid to form a 3D image in the center of the pyramid.

The scope for development of this project is vast. With this project as a base, the future will see several spin offs of the same catered to one’s personal needs.

The future lies in automation of everyday activities. Akin to this principle, the Servy Bot was created. The Servy Bot aims to reduce the time and effort required for service in the food industry. Designed on a small scale, the Servy Bot caters to any incoming requests within a single room. Considering an office environment where the room is divided into a series of cabins, the Servy Bot not only receives incoming requests but also manages to navigate its way through the environment to reach the desired location. A user may place a request with the help of a mobile application. The request is received by the bot and is then processed. Based on the request, it pinpoints the final destination. The bot is also equipped with a LCD screen to display the current status of the order. The minimum requirement is the access to facilities to generate a Wi-Fi hotspot for users to send their requests through the app.

Robots of such kind generally implement line tracing features. However, the Servy Bot is not your mainstream Line tracer bot. As opposed to common approaches, it makes use of RFIDs for navigation through the environment. RFIDs are placed at equal intervals to help the bot navigate and determine the proximity to the destination. “The problem with using GPS is that there is always an error of about plus or minus ten meters. We wanted the bot to be able to accurately navigate through the environment and so we decided to go with RFIDs to eliminate the possibility of errors”, says Raghul.

The Servy Bot additionally has the ability to detect the presence of oncoming obstacles. With the help of a sensor, when the bot detects someone approaching it within a five meter distance, it will stop. When the obstacle leaves the range of the sensor, the bot resumes its activities. Future iterations will see improvement in the external design with a sleeker look.

The mirror is an interactive model where the user may give voice commands to the system, with Amazon’s Alexa voice service as a framework for this feature. The user will have access to a variety of function, varying from simple features like date and time display to more complex ones such as updates on current weather, news, upcoming holidays and even access to one’s notifications from popular social networking sites like Facebook, Quora, and Twitter.

‘Mirror, mirror on the wall, who’s the smartest of them all?’ With the advent of smart phones, smart devices are making a huge impact in the world of technology. In this day and age, for every invention, there either exists a smart model or it is in development. What better way to join the smart trend than a smart mirror?

Inspired by the aforementioned idea, this year’s edition of Kurukshetra sees a smart mirror made from scratch using a Raspberry pi as a basis.

Given a normal two way mirror, a monitor is placed behind it. The entire system is powered by a Raspberry pi running in Chromium’s kiosk Mode. This enables data to be pulled from a web server set up on the Pi. By doing so, the display can be updated by modifying the source code in a suitable manner. The advantage of using a Pi allows it to be projected on displays of any size. When the user is done, the mirror reverts to a plain mirror.

The mirror is an interactive model where the user may give voice commands to the system, with Amazon’s Alexa voice service as a framework for this feature. The user will have access to a variety of function, varying from simple features like date and time display to more complex ones such as updates on current weather, news, upcoming holidays and even access to one’s notifications from popular social networking sites like Facebook, Quora, and Twitter.

In a time where life is incomplete without social media, privacy is also an important feature required in any application that gives one hands free access to their social media accounts. Akin to this, security features have been incorporated through facial recognition with the help of Image processing techniques.

AR Chessclose

What once was a hidden gem was suddenly brought to light with the release of Pokémon Go. Augmented Reality is the next big thing after Virtual Reality. This year’s edition of Kurukshetra also sees one of its first projects in Augmented Reality.

AR Chess finds its roots in a software called Unity. Using this software, a chessboard-like architecture was developed. Next, the initial location of all the coins as well as possible locations on the board had to be specified, where each coin was treated as an individual working element. Then Chess algorithm was implemented using a C# code with alpha beta pruning.

To initiate a game of chess, the user has to open the app. On opening the app, the user is presented with a menu with two options – to either start a new game or exit the application. The new game is initiated with a signal. In the current version of the app, the signal to start a new game is the presence of a 100 rupee note in the camera screen. However, the signal may be customized by the user. When the signal is encountered, the board is simulated on the signal, here being the note. Pieces can be moved with the help of a cursor. On moving the cursor over a piece and clicking it, the list of possible moves from the current position is displayed. On removal of the note, the game vanishes. Once the game has ended, the game vanishes and the user is redirected to the main menu. One of the difficulties faced in implementing this project was the coding. Algorithms are available for popular languages like Java, however, not for C#.

Traditional models of sphygmomanometers are analog in nature and are generally more preferable to digital sphygmomanometers, leading to an abundance of the former rather than the latter. However, digital sphygmomanometers provide several benefits over conventional models in that they do not require any manual intervention while checking a person’s blood pressure nor do they lead to any chance of parallax errors while reading the final value. Digital sphygmomanometers are also faster in comparison in calibrating blood pressure. To prove this point, the automated sphygmomanometer calibrates the user’s blood pressure via an analog mercury meter and a digital meter, aiming to show that with the advent of advanced technology in the medical field, digitization will help improve even the basic necessities in the medical world.

Digital sphygmomanometers in the market are in the price line of 1500-5000 rupees. The reason for the variation is the presence of the pressure sensor. Difficulty arose in the selection of a sensor that would not only be easy on the wallet but also provide the same level of functionality of as a high end senor model. The construction of both an automated and a manual pressure valve was an equally difficult time consuming task to carry out. Moreover, in the pursuit to create a more compact version of existing sphygmomanometers, procurement of suitably small components which were already hard to come by, was another challenged faced by the team.

The automated sphygmomanometer, overall, offers the following advantages of over conventional models

  1. More compact
  2. Faster calibration of blood pressure
  3. Elimination of the possibility of parallax error while taking the final reading
  4. Involves little to no manual intervention

Keeping the future in mind- the fact that digitization of medical records of a patient is soon to become a reality for the common populace- the automated sphygmomanometer will not be incompatible should this reform come to fruition. The automated sphygmomanometer also allows the blood pressure values of a patient to be added to their digital records.

Walking chairclose

The Conventional wheel chair is used to aid a differently abled person to move about easily with the use of its wheels. However, it is unable to move up or down a staircase, becoming a hindrance for the user who needs to look for an alternate route to reach another floor. The user cannot expect such an alternative to be present at all times, with the majority of public places involving a staircase at some point or the other.

So, in order to aid the disabled person to access the staircase effectively, we have replaced the wheel in the wheel chair with a walking mechanism. This mechanism contains four pairs of links which will climb the staircase with the help of a set of motors. This will also help them to traverse through places with irregular surfaces.
