Gautham Narayan Narasimhan

Hello! I am currently a Research Assistant at the Robotics Institute (RI) at Carnegie Mellon University. Previously I completed my masters thesis with Prof. David Held at CMU.

I study machine learning algorithms that enable robots to perceive and manipulate general purpose objects. Currently I'm working on model based reinforcement learning for robotic pouring tasks.

clean-usnob Learning Material Properties using a Differentiable Simulator for Liquid/Granular manipulation
Gautham Narayan, Xingyu Lin, David Held
In progress

Currently training a Material Point Method based differentiable simulator to learn material properties. Cross Entropy Method has shown good performance for trajectory optimization once the material properties have been learnt. More details coming soon ...

clean-usnob Self-supervised Transparent Liquid Segmentation for Robotic Pouring
Gautham Narayan, Kai Zhang, Ben Eisner, Xingyu Lin, David Held
ICRA 2022 and abridged at NeurIPS 2021 Deep Generative Models Workshop

A novel segmentation pipeline that can segment transparent liquids such as water from a static, RGB image without requiring any manual annotations. We show that this system can run in real-time and aid in tasks such as robotic pouring.
