Objects are inconsistent
Mugs, bags, towels, drawers and containers vary in shape, friction and stiffness. Manipulation must work with incomplete information.
Touch closes the gap
Vision estimates where an object is. Force and tactile sensing reveal what happens at contact — slip, compression and successful closure.
Regrasping matters
Humans change grip mid-task constantly. Robots need similar strategies to orient plates, fold cloth or fit objects into storage.
Hands versus grippers
Five-fingered hands maximize compatibility but add cost and control complexity. Simpler grippers trade versatility for reliability.
Hybrid software
Motion planning tools such as MoveIt 2 can provide geometric checks while learned policies increasingly handle perception-to-action behavior.
