Head touch sensor

A touch-sensitive patch on top of the robot's head. When someone taps, pats or strokes it, the robot notices and reacts, for example with a small movement. It works like the touch buttons on a phone or a cooker, sensing a finger through the cover without any part moving. It is there to make the robot feel friendly and responsive, rather than to help it work.

Strengths and trade-offs

Our analysis

Strengths

Gives people a simple, natural way to get the robot's attention.

No moving parts, so nothing to wear out.

Tiny, cheap and uses very little power.

Tells different kinds of touch apart, so each can trigger a different reaction.

Trade-offs

Only covers one small patch, so it is not a sense of touch for the whole body.

Mainly for show and interaction, it does not help the robot do work.

Can be set off by accident, for example by a bump or a wet surface.

Why robot makers choose it

Our read

The X2 is sold for shows, schools and greeting visitors, where being pleasant to be around matters. A pat on the head that gets a response makes the robot feel more alive, and a touch chip costs very little to add.

This is our reasoning from the public facts. No maker has confirmed it.
