I stand in front of a lanky two-legged robot stomping along a treadmill. I watch, all impressed, until the researcher next to me tells me to trip it. The thing looks expensive, so I hesitate. Really, he tells me, it’s OK. And he probably knows better than I do, so I drag my boot along its shin like a good soccer trip.
