The algorithm begins at the start point, then repeatedly throws random samples into the environment. Each time a sample appears, the tree finds the closest branch it already has and takes a small step toward that sample, as long as the motion does not collide with an obstacle. What makes this work is the geometry of empty space. Large unexplored regions are more likely to attract new samples, so the tree naturally stretches into open areas without needing a full grid, a full wavefront, or a complete map of every possible route. At first, the motion looks almost chaotic because the tree is reaching in many directions at once, but over time its branches probe corridors, slide around obstacles, and eventually touch the goal region. Once that happens, the path is recovered by tracing the connected branches backward from the goal to the start. #RRT #MotionPlanning #PathPlanning #Robotics #ShortestPath #ComputationalGeometry

In 1998, Steven LaValle introduced a beautifully strange way to search through a complicated world Don’t fill the whole space, and don’t try every possible path. Grow a tree. That is the idea behind Rapidly-Exploring Random Trees, or RRT. #RRT #MotionPlanning #PathPlanning #Robotics #ShortestPath #ComputationalGeometry

I wrote an article on "Dijkstra vs. A*": explained with math, intuition, and Python implementation: tinyurl.com/yzdp6hbd I also explain how i built an interactive path-planning demo, and I compare the two algorithms based on their efficiency: #Robotics #PathPlanning

Day 27/32: Robot Navigation Path Planning (The Strategy) Knowing where the kitchen is (SLAM) is one thing. Walking there without hitting the dog is another. This is called Path Planning. When you ask the @openmind_agi OM1 to "go to the kitchen," it doesn't just start walking. In a split second, it runs a simulation: It identifies the start point (Sofa) and end point (Fridge). It calculates a "trajectory" - which means the specific line to follow. It checks for obstacles (Shoes on the floor? A chair pulled out?). If the path is blocked, it recalculates instantly. It’s like having Google Maps running inside your head for walking across your living room. #OpenMind #PathPlanning #AI #Navigation #Tech

The main difference between A and Dijkstra’s algorithm is that Dijkstra’s doesn’t use a heuristic. I’m so comfortable implementing Dijkstra and A* that I could write it even if someone woke me up from sleep. #robotics #pathplanning

Start with a priority queue to explore nodes by f = g h. Track g (cost from start) and h (heuristic to goal). Expand lowest f first, update paths if cheaper routes appear. #robotics #pathplanning
