> The power system is the primary limitation here, but it might be possible to use a solar cell to cut down on battery requirements ... with a long-range wireless link and a vision system, it’s possible to add sophisticated vision-based autonomy to tiny robots by doing the computation remotely
Since WiFi can be used to see through walls and ceilings of buildings and homes, using low-cost passive sensors, such devices can be autonomously navigated. E.g. for indoor use, knowing light source locations for charging and camouflage.
> our dataset provides a collection of Wi-Fi signals that are recorded for 40 different pairs of subjects while performing twelve two-person interactions. The presented dataset can be exploited to advance Wi-Fi-based human activity recognition in different aspects, such as the use of various machine learning algorithms to recognize different human-to-human interactions.
