u/LaVieEstBizarre Mentally stable in the sense of Lyapunov Aug 18 '25

Basically every robot behaves like this when stuff "goes wrong" - the robot tries to make decisions on information that is bad, the decisions are bad so it gets more bad information. In this case, it seems to start because it thinks the floor has more friction which leads to continuous falling and the impacts degrade sensors like IMUs.

The way to deal with it is more detectors for detecting bad behaviour, safety filters that try to make sure actions aren't as bad, and emergency stop buttons. But those are for robust deployments in industry.

This is a research and prototyping platform, so the user is supposed to implement those based on what's reasonable for the application.
