Research Projects
Semi-Autonomous Stair-Climbing Wheelchair
Team Members : Yogita Choudhary and Pratyush Kumar Sahoo
Project Advisor: Dr. Shyam Kamal
In this project, we have developed a stair-climbing wheelchair prototype. The prototype is based on a three-pulley track-based mechanism. The testing of the system is done in the Gazebo. Data-driven methods are used for modeling the wheelchair system. More details can be found here.
Medi-Assess : A Machine Learning based automatic triaging system
Team Members : Pratyush Kumar Sahoo, Shirley Kokane and Harsh Narayan Tiwari
Project Advisor: Dr. Biplav Srivastava
To aid the process of triaging in Emergency Departments of over-stressed settings an automatic triaging system is developed trained on the NHAMCS dataset. The developed model very accurately differentiates critical patients. Further details can be found here.
Design of a Tracheal Sensor for Detecting and Monitoring Obstructive Pulmonary Disorders
Project Advisor: Dr. MM Nayak
A tracheal sensor is developed to monitor Respiratory Rate and Sleep Apnea. The sensor is designed by enclosing a Piezoelectric Transducer in a 3D printed housing with a diaphragm creating an air-tight cavity. A charge amplifier is further used for signal acquisition. Presentation
Implementing a non-smooth PI controller using DNA strand displacement reactions.
Project Advisor: Dr. Shyam Kamal
A controller helps to achieve the desired response in a process. Biological processes require proper control mechanisms to take place effectively. Most of the chemical pathways in the body, work through a closed-loop feedback control mechanism. A common control process that occurs in a living cell is for the activation of a protein by the Covalent Modification Cycle that produces the required amount of activated protein when driven at different rates in a cell-signaling cycle. It has been seen that one of the possible ways to design a biological controller is by using DNA Strand Displacement Reactions modeled via Chemical Reaction Networks. In this project, a Non-Smooth Proportional Integral Controller using mathematical modeling and Chemical Reaction Networks for a Biological System is simulated. Report
