Hi, my name is
Radha Lahoti
Welcome to my website!
I am a Robotics Researcher pursuing my Dual Degree (B. Tech. + M. Tech.) in Mechanical Engineering at IIT Bombay. My research interests are primarily dedicated to the fields of Design, Dynamics and Control for bio-inspired robots.
About Me
I am a Mechanical Engineering student currently in the fifth year of my Dual degree (B. Tech. + M. Tech.) program at IIT Bombay, specializing in Computer-Aided-Design and Automation, and pursuing a minor degree in Aerospace Engineering.
I am deeply interested in the fields of Multi-body Dynamics and Control, Mechanical Design, Biomechanics, Robotics and Automation, and their applications to Bio-inspired and Biomedical Robots and Aerial Vehicles.
I am a sport enthusiast and a dedicated basketball player. I also love dancing and sketching and always am on the lookout for adventures similar to the ones in books! Yeah I am an avid reader, I like adventure stories, detective stories, science fiction and suspense thrillers.
Here are a few technologies I've been working with recently:
- Python
- C++
- MATLAB
- Simulink
- SolidWorks
- TIVA CCS
- Arduino IDE
- ANSYS
- ADAMS
- Fusion 360
- AutoCAD
- LaTeX
These are some of my recent achievements:
- Innovation Grant Awardee, IISc Bangalore
- Department Rank 1, Mechanical Engineering, IIT Bombay
- Institute Academic Prize 2021
- All India Rank 386, JEE Advanced 2017
Work Experience
Controller Design & Tuning For Three-Way-Catalytic Converter @ Purdue University
June - August 2020
Guide: Prof. Gregory Shaver
(School of Mechanical Engineering, Purdue University)
Developed a PID controller utilizing the models of feed-gas and Three-Way-Catalyst (TWC) to robustly control the oxygen storage level of the catalyst at a desired set point, for efficient automobile exhaust emission control in the run for clean energy
- Studied the working of a Three-Way-Catalytic converter and fractional oxidation state based emission control
- Obtained a linearized state-space TWC plant model and designed a Routh-Hurwitz stable PID controller
- Reduced the steady state error from an initial value of 21% to 5.68% by tuning the controller gains using Ziegler-Nichols technique on the non-linear plant, and to 8.05% using Lead Lag design technique on the linearized plant
Key Research Projects
Featured Project
Bat-like Biomimetic Wing
This project is aimed at designing a robotic wing possessing morphing capabilities like a batwing, developing a multibody kinematic and dynamic model, implementing tensegrity-based actuation and control, and fabricating a prototype for achieving highly maneuverable artificial flight.
This project has won the prestigious Student Innovation Grant by ARTPARK (AI & Robotics Technology Park) IISc Bangalore, awarded to 10 select projects across India.

- 3D Printing
Featured Project
Control of TWC Converter
Developed a PID controller utilizing the models of feed-gas and Three-Way-Catalyst (TWC) and tuned its gains to robustly control the oxygen storage level of the catalyst at the desired setpoint, for efficient automobile exhaust emission control in the run for clean energy.
- MATLAB
- Simulink
Featured Project
Flapping Wing UAV
Designed and built an Ornithopter with a wing span of 2.8 m inspired by the bird Condor. The wing is capable of PID-controlled double flapping (has a functional elbow joint) and pitching like the wing of large predator birds.
- Solidworks
- Arduino
- PID
Featured Project
Stair Climbing Bot
Designed a load-bearing stair climbing bot to help people with reduced mobility and/or ease carrying heavy loads up a fleet of stairs by utilizing a base rocker-bogie mechanism and compensating for the deviations of the seat from horizontal orientation.
This project was selected for presentation in the Virtual Research Symposium ‘21 (IIT Bombay and NTU Singapore)
