Research Projects

Concrete Compressive-Strength Prediction Algorithm using Machine Learning

Research Project under Dr. PS Rana of TIET Patiala and Dr. Nishtha Hooda of IIIT Una

Measuring the concrete's compressive strength is an ever-important task in the civil engineering industry. A collaborative effort has been put up between three institutes to predict the compressive strength of concrete samples using advanced gradient boosting methods, after extracting features such as Water %, Superplasticizer %, etc. A MAPE of 1.2% was overall found after the training of the model.

June 2020 - February 2021

Research and Development of Smart Fruit Quality Manager

Undergraduate Research Project under Dr. PS Rana , Dr. AK Singh and Dr. RK Singla of TIET Patiala

Developed a mechatronic system for segregating fruits based on their grade by using Spectroscopy and Machine Learning. The fruits are fed to the system and the machine classifies the fruits using Azure Custom Vision API and then using Spectroscopy and a custom gradient boosted ensemble, it grades the fruits into separate classes. The entire system works with the help of an Arduino Mega controller and a Raspberry Pi.

August 2019 - October 2019

Programming Of Remote Surveillance Robot And Odometry Sensor Calibration Protocol For CMR's

Research Internship Project under Prof. S.K. Saha at IIT Delhi

Developed the Software and the Mechatronic system for RoboMuse3XT for helping the robot carry out remote surveillance by controlling it with a PS3 Joystick using ROS. Along with that, I collaborated with another intern to develop a unique robot odometry calibration protocol using a 2D Laser Scanner and the Iterative Close Point method, for RoboMuse V, to calibrate the robot wheel odometry, using a unique path (protocol) for the robot to run.

Other Projects

Development of the Home Gym Spotter- Pushups Counter

Self Guided

Developed a Computer Vision solution for counting pushup repetitions while working out from home. The solution is based on the classification of frames using a MobileNetV2 CNN model, specifically trained using transfer learning, with an accuracy of 90% on the test dataset.

August 2020

Development of a ROS Node for IMU-BNO080 UART Protocol Mode

Peer Robotics, Gurgaon

Developed a unique ROS Node for acquiring data from the BNO080 IMU (Sparkfun VR IMU) by tapping in the UART-RVC protocol, without using an additional micro-controller. Developed a plug-and-play system using a USB-TTL Converter, that would lead to a saving of Rs. 2000+ per robot manufactured.

August 2019 - October 2019

Development of a speech controlled buggy using ROS

Under the guidance of Dr. Ashish Singla of TIET Patiala

Developed an Arduino 2-wheeled Buggy and used CMU's - PocketSphinx and a ROS node to control it using voice commands. Also developed a web app using ROS-Bridge to control the buggy over the internet.

Interests

Apart from being a mechatronics engineer, I enjoy working on projects involving graphics, music, movie-making, and creative designing. Other than that, I enjoy traveling to places and documenting them for myself. A music enthusiast, I love talking about and listening to Rock, Hip Hop, and Indian Genres of Music.

Sometimes, when I am not watching TV Documentaries, I try to pick up my guitar and learn something or the other on it. Also catch me on ClubHouse, trying to give talks about career, social media trends, and randomly blabbering about not investing in the DogeCoin.
