TACTIC: Tactile and Vision Conditioned Contact-Centric Control for Whole-Arm Manipulation

Rishabh Madan, Angchen Xie, Samantha Saak, Andres Blanco, Dohyeok Lee, Sarah Grace Brown, et al.

Whole-arm manipulation involves direct contact with the environment while the robot completes a task by distributing contact across multiple links as contacts form, slide, and break. This setting breaks common implicit assumptions in many learning-based manipulation pipelines: ar…

FADA: Few-Shot Domain Adaptation via Dynamics Alignment for Humanoid Control

Angchen Xie, Nikhil Sobanbabu, Ishayu Shikhare, Alan Wang, Max Simchowitz, Guanya Shi

High-precision humanoid control is limited by target-domain dynamics mismatch, where the same control objective can induce different realized motions under changes in terrain, payload, or actuator response. Existing methods either pursue zero-shot transfer through domain randomiz…
