Step size

A Rapidly-exploring Random Tree grows toward random points in free space, quickly filling the map and snaking around obstacles to connect start (blue) to goal (yellow). It is a cornerstone of motion planning for robot arms, self-driving cars, and drones — fast even in high dimensions where grid search fails.

Governing equation

x_{n e w} = x_{n e a r} + ε \frac{x _{r an d} - x _{n e a r}}{∥ x _{r an d} - x _{n e a r} ∥}, ε = 18, N = 0

Reading this result: No path yet at step 18 — the tree ran out of iterations before reaching the goal. Try Replan or a smaller step.
