Propagating Elevation-Map Uncertainty Through the Contact Maximum in Closed Form
Aleš Kučera, Karel Zimmermann
Risk-aware planners score paths on uncertain elevation maps using the path cost's mean and standard deviation. Modeling rigid contact, however, requires computing a maximum over se…

Ostrich: Taking Large Strides Through Stiff Contact in Differentiable Dynamics
Aleš Kučera, Karel Zimmermann
Three properties determine whether a differentiable simulator can drive gradient-based optimization through contact: simulation accuracy, gradient reliability, and per-iteration co…
