Workshop at Robotics: Science and Systems 2022
July 1st, 2022
Handling contact is a fundamental challenge in robotics. We want robots to interact with the world to do something useful, which often requires physical interaction with the environment. Whether it is a warehouse arm picking an object from a box, a search and rescue robot walking over broken terrain, or a home assistance robot clearing the dishes, robots need to be able to enable, plan for, control through, sense, withstand, and learn about contact events. However, contact necessarily involves a sudden change in dynamics – the effects of motion while touching and almost touching can differ dramatically. Because of this, many robots seek to avoid or minimize the effects of contact, for example by slowing down before touching an object. Furthermore, robots go through great lengths to avoid unexpected contacts, by operating in controlled environments or taking excessively conservative paths around obstacles.
This workshop seeks to push the field toward a future where robots aren’t afraid of contact. Where accidentally bumping into something isn’t catastrophic, and where the robot doesn’t treat everything in the environment as if it were made of egg shells. To get there, we need to reason about contact while considering all aspects of the system design: the mechanism, sensing, control, planning, and learning must all account for the challenges of real-world contact. This is also an issue that cuts across different application domains such as manipulation or locomotion. Thus this workshop is designed to bring together researchers from across the robotics field to explore new approaches to tackling this fundamental challenge.
To get the conversation started, here is a list of topics and questions for participants to think about (but other topics within the spirit of the above description will also be considered):
- Reactive or online planning and control to initiate and leverage contacts.
- Robustness to expected or unexpected contact events.
- Is a model-based structure necessary, or can unstructured learning methods succeed? What types of problems might require or benefit from structure?
- Making sense of touch: leveraging spatially rich tactile sensing.
- The role of design and novel shapes to control interactions.
- Interacting with soft and deformable surfaces, and leveraging softness for robustness.
- How does the manner (fast/slow, accidental/intentional/adversarial) or physics (soft/hard, point/surface, slippery/sticky) affect which solution(s) might be appropriate?
