Mateo Guaman Castro

Previously, I was a Master's student in Robotics in the Robotics Institute at Carnegie Mellon University, advised by Prof. Sebastian Scherer as a member of the AirLab and the Field Robotics Center.

Before that, I studied electrical engineering at Tufts Univesity, where I recieved my BS. I was a researcher in the Multimodal Learning, Interaction, and Perception Lab (MuLIP) advised by Dr. Jivko Sinapov and Dr. Evana Gizzi. I was also a research intern working with Dr. Howie Choset in the Biorobotics lab at Carnegie Mellon University, and Dr. Guillaume Sartoretti in the Multi-Agent Robotic Motion (MARMoT) Lab at the National University of Singapore.

My research lies at the intersection of Robot Learning, Computer Vision, and Field Robotics. I am interested in self-supervised learning, reinforcement learning, and representation learning for fast adaptation and generalization in unstructured environments. My ultimate goal is to develop robots that probe when uncertain, and make mistakes only once, if at all.

• September 2023: I will be joining UW as a PhD student in Robotics!
• July 2023: I attended ICML 2023, where I served as Social Chair at the LatinX in AI workshop.
• July 2023: I defended my Master's thesis at Carnegie Mellon University! Here is the recorded video.
• May 2023: I presented two conference papers and one workshop paper at ICRA 2023, my first ever in-person conference.

We propose a self-supervised method to predict traversability costmaps by combining exteroceptive environmental information with proprioceptive terrain interaction feedback.

We present an inverse reinforcement learning-based method that efficiently predicts uncertainty-aware costmaps for off-road traversability via conditional value-at-risk (CVaR).

In this work we discuss the improvements to our previous dataset, TartanDrive.

In this work, we investigate methods for life-long creative problem solving (LLCPS), with the goal of increasing CPS capability over time.

We present a formal framework and implementation in a cognitive agent for novelty handling and demonstrate the efficacy of the proposed methods for detecting and handling a large set of novelties in a crafting task in a simulated environment.

We introduce a unified framework for creative problem solving through action discovery. We describe two methods which enable action discovery at a declarative and neurosymbolic level, namely through action primitive segmentation, and behavior babbling, respectively.

We describe a method for discovering new action primitives through object exploration and action segmentation, which is able to iteratively update the robot's knowledge base on-the-fly until the solution becomes feasible.
