Research Experience

SLIDER - Master's Research Project | Robot Intelligence Lab, Imperial College London, UK | September 2018 - October 2019

The Imperial SLIDER is a novel bipedal walking robot without knees having 10 degrees of freedom.
Minimized the weight to strength ratio by using aluminium CNC and high strength 3D printing techniques.
Reduced the backlash and back-drivability of gears for performing the motion effectively.
Designed and manufactured a new double stage cycloidal gear drive with a reduction ratio of 1:36.

Pratham is IITB's first student technical initiative in collaboration with ISRO, successfully launched the satellite on 26th Sept 2016; the team commended directly by Indian Prime Minister and State Chief Minister.
Secured a launch slot for the satellite and successfully completed design and review to meet ISRO standards.
Performed integration and testing in the final phase of completion as a part of 20 membered contingent that went to ISAC, Bengaluru for CDR (Critical Design Review) meeting.
Iteratively simplified the simulation by approximating the CAD model of the satellite, thus reducing the simulation time by 90%; assumptions verified by ISRO scientists.
Developed the finite element of the satellite and performed thermal simulations to analyze and maintain the temperatures of critical satellite components within their operating range (-20°C to 80°C).

Explored phenomenon exhibited by two-phase flows around the falling particles (principally solids and liquids) using high-performance computing systems.
Investigated the consequence of the randomness of velocities, angular velocities and hydrodynamic forces of interacting rigid particles falling under gravity through viscous fluid at low Reynolds number (approx. 50).
Applied Direct Numerical Simulations (DNS) method to study the evolution of a single particle and dispersion of the cluster of particles in viscous fluid with different resolutions (approx. 10-70 million cells).

Inspired by the flight of birds, the project aim was to build a fully functional ornithopter which can be used for surveillance, military applications, traffic monitoring, etc.
Designed and developed a consolidated electrical circuit using a load cell, operational amplifiers and micro-controllers to measure the forces developed by airflow over the wing.
Continued the structural setup in which the wing is placed on a rotary mechanism to simulate airflow and to determine the lift, thrust and drag developed by flapping wing.

Simulated the environmental model considering conduction, forced convection, natural convection and radiation in ANSYS Fluent.
Modelled the physical geometry in SolidWorks and studied the basics of Computational Fluid Dynamics.
Analyzed the cooling rates for various temperatures of chilled water.

A miniaturized version of automated robotic arms used on production lines in factories and industries.
Designed and fabricated an Arduino based miniaturized robotic arm performing autonomous repeated motion once inputs are given by the user.
Designed the structure using Auto-CAD; used Servo motors as actuators
