VOTE: Vision-Language-Action Optimization with Trajectory Ensemble Voting
Juyi Lin, Amir Taherin, Arash Akbari +11
Recent large-scale Vision Language Action (VLA) models have shown superior performance in robotic manipulation tasks guided by natural language. However, current VLA models suffer…
Socially-Aware Autonomous Doorway Traversal and Payload Delivery for Emergency Assistance
Andrew Snowdy, Ananya Trivedi, Sarvesh Prajapati +2
In this work, we focus on the scenario of a robot-assisted emergency evacuation. We consider two capabilities relevant to such a setting. The first is opening doors ahead of the pe…
TACTFUL: Tactile-Driven Exploration For Object Localization and Identification in Confined Environments
Shivani Kamtikar, Chung Hee Kim, Camilla Tabasso +3
Humans effortlessly locate and identify objects by touch alone, even without vision. In contrast, robotic systems rely heavily on vision and struggle with autonomous tactile explor…
JOIN: Anchor-Grasp-Conditioned Joining via Opposition, Inference, and Navigation for Bimanual Assistive Manipulation
Drake Moore, Matt Cheng, Xiang Zhi Tan +1
Assistive mobility and manipulation platforms have received increasing attention as a means of restoring independence to individuals with disabilities. While effective for many bas…
Just Keep Prompting: Evaluating Repetitive Socratic Prompting in VLMs
Shayda Moezzi, Bishoy Galoaa, Lorena Genua +2
Deploying Vision-Language Models (VLMs) in real-world settings requires not only strong visual reasoning but also stability under sustained conversational pressure. We introduce Ju…
Grasp, Slide, Roll: Comparative Analysis of Contact Modes for Tactile-Based Shape Reconstruction
Chung Hee Kim, Shivani Kamtikar, Tye Brady +2
Tactile sensing allows robots to gather detailed geometric information about objects through physical interaction, complementing vision-based approaches. However, efficiently acqui…
