I’ve noticed that, in practice, it is very difficult to accurately gauge 6 feet consistently. Somehow 6 feet between friends looks much shorter than with strangers. Great idea and project from draakje156 on Hackster.io:
In this time with COVID-19 you see many people standing far too close to a desk, cash register or otherwise. People are not fully aware of the distance of 1, 5 meters (6 feet), for example.
I came up with the idea to make a friendly battery powered robot that can easily stand on a table desk or otherwise.
This robot measures the distance between it and the approaching person and gives a notification. The robot indicates a programmabletone and its hat lights up red. If you come at a safe distance again, the hat will turn green again.
