This video from Computerphile provides a comprehensive overview of path planning for robotics, explaining how robots navigate complex environments. It details the fundamental 'sense-plan-act' cycle and demonstrates a simulated robot using ROS. The video thoroughly explains the A* algorithm for optimal pathfinding in grid-based maps and introduces Rapidly Exploring Random Trees (RRT) and RRT* as more suitable sampling-based approaches for high-dimensional problems like manipulator arms, concluding with a discussion on hybrid algorithmic strategies for robust robot navigation.
