your body interacts with them:
"... a fine beam ultra-wideband (UWB), multi-Gigahertz radio frequency
(RF) sensor array ... mounted on the robots lightweight arm transmits
highly directional wideband signals that are able to penetrate
reinforced concrete walls at an extended range. Reflections from the
targets are captured by a signal detector circuit in the receiver and
amplitude and delay information is then processed in an integrated
signal processor to track the targets in real time."
