On-Robot Reinforcement Learning with Goal-Contrastive Rewards

ICRA 2025

Reinforcement Learning (RL) has the potential to enable robots to learn from their own actions in the real world. Unfortunately, RL can be prohibitively expensive, in terms of on-robot runtime, due to inefficient exploration when learning from a sparse reward signal. Designing dense reward functions

Snake Robot with Tactile Perception Navigates on Large-scale Challenging Terrain

ICRA 2024poster

Along with the advancement of robot skin technology, there has been notable progress in the development of snake robots featuring body-surface tactile perception. In this study, we proposed a locomotion control framework for snake robots that integrates tactile perception to augment their adaptabili…

Reducing errors in object-fetching interactions through social feedback

ICRA 2017poster

Fetching items is an important problem for a social robot. It requires a robot to interpret a person's language and gesture and use these noisy observations to infer what item to deliver. If the robot could ask questions, it would help the robot be faster and more accurate in its task. Existing appr…
