A robot learns what a firmer wipe means

What changedA Barcelona team used paired robot arms to record how firmly a person intended to press during a demonstration. A trained robot then pushed harder when asked for a firm wipe. That is a step toward teaching touch through examples, though the evidence comes from one wiping task and one robot platform.

The useful part

Why it matters

Useful physical instructions need to express how hard to push, as well as where to move.

Keep in mind

Good to know

Evidence covers one wiping task on one robot platform with a small rollout budget. The causal contribution of the force input remains unresolved.
