Contact-mode decision making
Robots must decide when to grasp, push, drag, brace, lean, pin, wedge, pivot, or exploit the environment, and how to transition between those strategies under uncertainty.
Workshop Theme
Recent advances in robot learning, control, perception, and planning have enabled mobile robots to navigate complex environments and interact more capably with the physical world. Legged robots, humanoids, and mobile manipulators now perform tasks that require whole-body motion, forceful interaction, and adaptation under uncertainty.
Many real-world loco-manipulation problems cannot be solved by grasping alone. Robots must combine prehensile skills, such as grasping and carrying, with non-prehensile skills, such as pushing, dragging, pivoting, bracing, or using sustained body-object contact. The contact strategy is directly coupled to locomotion, balance, onboard sensing, planning, and whole-body control.
This workshop brings together researchers in legged locomotion, mobile manipulation, non-prehensile manipulation, whole-body control, contact-aware planning, onboard perception, and sim-to-real transfer to identify shared challenges and promising research directions.
Core Challenges
Whole-body coordination under contact
Contacts involving a robot's arms, legs, torso, or base—as well as objects and the environment—affect balance, mobility, force regulation, and task success.
Reasoning under uncertainty
Robots must act despite uncertainty in friction, mass, compliance, center of mass, contact location, slip, object geometry, terrain, and other hidden state.
Generalization across embodiments
The field needs principles and representations that transfer across fixed-base arms, mobile manipulators, quadrupeds with arms, humanoids, soft robots, and dexterous hands.
Benchmarks, metrics, and infrastructure
Progress requires shared task families, metrics, simulation assets, and real-world protocols that capture robustness, safety, recoverability, contact efficiency, and generalization.
Workshop Format
Invited talks
Four invited talks will frame the central open problems and leave time for direct Q&A on contact-mode selection, whole-body coordination, and uncertainty.
Lightning talks and posters
Accepted workshop papers will be introduced through short spotlights and then discussed in an interactive poster session.
Panel and community report
A moderated panel will bring together speakers, authors, and attendees, with key open problems and research directions summarized in a post-workshop report.
Call for Papers
Short workshop papers
We invite 2–4 page workshop papers on contact-rich loco-manipulation, including new results, early-stage ideas, benchmark proposals, position papers, open problems, negative results, and failure analyses.
Prehensile and non-prehensile skills
Whole-body control
Contact-mode representations
Multimodal sensing
Sim-to-real transfer
Audience
Researchers across robot learning, locomotion, manipulation, control, perception, planning, and benchmarking are welcome. We especially encourage late-stage PhD students, postdoctoral researchers, and others early in their careers to participate and present their work.
