Friction is a pervasive nonlinearity in mechanical systems, arising at interfaces from the microscale asperities of surfaces and manifesting in macroscopic performance degradation, wear and control ...

Deploying world models in real robotic systems requires a step that receives less attention than the models themselves: ...

Atoms slip against one another, eventually sticking in various combinations. Tectonic plates do the same, sliding across each other until they stick in a stationary state. Everything from the tiniest ...
