A revolutionary Lighter Than Air (LTA) aerial surveillance drone designed to address a major challenge of low altitude aerial surveillance: limited flight time. The key to its impressive capabilities was its innovative LTA system, which canceled out the effects of gravity, allowing it to remain afloat without external force. Additionally, the drone was equipped with a sophisticated algorithm that drove its control system, allowing it to combat winds speeds of up to 10 m/s or 37km/h. To make the system self-sufficient, solar cells were positioned on the drone's wide surface area to provide extra power to the payloads and extend the flight time. 

I had been working on my start-up, Grass Root Advanced Systems, for a few years before finally launching it. Over the past few years, I had explored various markets for our technology and worked hard to improve the product. Recently, I had focused on celestial applications. I scaled the product up so that it could carry small satellites and payloads up to 2000kg into the stratosphere (35km).

I was awarded INR 10,91,000 from Dassault systemès for the project, "Amphibious Rover for Disaster Rescue and Surveillance". As the leader of the team, I was responsible for designing and fabricating the product and our goal was to achieve mobility in all three mediums (land, air, and water) with a system of rovers. To ensure the rover could move effectively, we conducted extensive research and evaluated several different options before deciding on an optimal drivetrain mechanism. This mechanism provides an optimal combination of power, agility, and maneuverability, allowing the rover to traverse through slushy terrain with ease.

The prototype was composed of four integrated modular robots, each with its own specific task. I was also responsible for working on various domains that are important for robotics, such as mobility, computer vision, and autonomous flight of drones. By developing the locomotion of the legged rover, using OpenCV for detecting people and estimating distance with Intel’s RealSense LiDAR, and way-point navigation for autonomous flight of drones, I was able to successfully create the prototype and prove its viability.

The goals of this project were to develop a computer vision model that identified the subject of interest as input from the user and measured its distance from the camera using its inbuilt LiDAR.

For this project, I decided to use a combination of the two systems available on Intel RealSense to create a depth estimation system that would provide accurate depth measurements with less noise. The system was based on a combination of a laser-based Lidar and an Infrared (IR) light-based camera. The Lidar was used to capture the coarse measurements of the environment and the IR camera was used to capture the fine details and to remove the noise from the measurements. This was done by calibrating the two systems such that the measurements from the Lidar and the camera were in sync with each other. The output of the system was then used for various applications such as object detection and tracking, collision avoidance, and navigation. 

“EFFI CYCLE” is a national-level competition in which we conceived, designed, and fabricated a three-wheel configuration vehicle powered by human and electric power that is capable of seating two passengers. We designed and developed this vehicle from scratch, and I took the responsibility of the design lead and the primary driver. The designed and fabricated vehicle must be aerodynamic, engineered for performance & safety, with ergonomic design to qualify for the technical inspection and be fit to race.

Efficycle is an annual event where engineers from all over the country design and fabricate a dual-seater trike, that will undergo a series of rigorous inspections, before being allowed to race. Each year the event takes place at Lovely Professional University (LPU), Punjab.

"EFFI-CYCLE is an initiative of SAEINDIA Northern Section with the objective of providing an opportunity for the students, to explore the “Environment-Friendly and Economical” solutions for the day-to-day mobility needs of people. The event task is to conceive design and fabricate a prototype of a three-wheel configuration vehicle, capable of seating two passengers and powered by human and-electric hybrid power." - SAE India.

Developed a mechanical test bench to simulate and calibrate a computer vision model that detected the presence of humans around a forklift in a warehouse and automated its braking. The main challenge of the design was to counter in the parameters like forklift's weight, which varies depending on the material it is carrying, the surface and the frequency of people crossing paths with the forklifts. To solve this challenge, I developed a system that would calibrate the computer vision model based on the forklift's weight and other variables. By testing different scenarios, I was able to ensure that the system was effective in detecting humans and accurately braking the forklift in different situations. The project was a success, and the test bench was able to accurately detect and respond to the human presence without any errors. 

Smartphones are usually very efficient at dissipating heat because they use low-power-consuming processors that shouldn’t produce excessive heat. Occasionally if we are using GPS along with the internet turned on or using high capacity apps or games or are transferring a lot of data the phone will produce more heat than normal though it should be within tolerance levels. If we feel it's getting too hot or the heat is not going away then we usually give the phone a rest. By giving a rest we usually, close down all apps turn of data/Wi-Fi/Bluetooth/. We find that it cools down fairly quickly. It has been reported that certain cases will hinder the phone's ability to lose heat, though most cases should be ok. If our phone is always hot when doing normal operations, it may be that the battery is faulty or the PMS (power management system). The main object of the proposed invention is to design a stand-alone heat dispensing cum mobile phone holder for mounting in vehicles while using the GPS for navigation. It is so designed that the operation will be completely self-sustaining by not using any power from the vehicle itself. But through solar cells mounted on it. Heat dispersion through forced convection This stand-alone system has a cooling fan mounted right on top of the phone’s processor and battery, which are the major heat generation zones. Thus, they regulate the temperature by blowing air from the surroundings. This will bring the device’s temperature close to the ambient temperature. Self-sustaining heat dispersion system This mechanical system comprises a much-enhanced method of power generation for using solar cells. The cells are positioned in such a way that they are always pointed towards the light source. We have achieved this by placing the cells which will be infused in the rubber medium of the suction cup, that will be mounted on the glass surface of a car.
