Watch a cleaning robot think
A robot walks around a simulated office among people. It looks for drink cans, works out which ones are abandoned, takes those to the bin — and must never take someone's drink or bump into anyone. These are replays of its test runs.
- Reality — people, cans and the robot where they really are.
- What the robot believes — a ring around every can it has noticed. The green arc fills up while nobody is near the can; when it's full, the can counts as trash.
- Callouts appear whenever the robot decides something. Click anything to compare the truth with the robot's belief.
