Dijkstra-based DORA algorithm enhances robot navigation in uncertain environments

Researchers have developed DORA, a novel algorithm for robot navigation that leverages Dijkstra's algorithm for stochastic shortest path problems. DORA operates online, requiring a fixed number of shortest path oracle calls per episode without needing to estimate transition kernels. This approach proved effective in simulations across various benchmarks, matching the performance of value iteration while significantly reducing computational effort and minimizing unwanted contacts with dynamic obstacles.
