We present an example-based planning framework to generate semantic grasps, stable grasps that are functionally suitable for specific object manipulation tasks. ...
We propose to use partial object geometry, tactile contacts, and hand kinematic data as proxies to encode task-related constraints, which we call semantic constraints. ...
For the next step, we will be considering possible ways to generalize the semantic affordance map so that it would be easier to transfer grasping knowledge between objects and tasks while preserving their ...
