Step by step Guide: A* algorithm | A star for 2D Path Planning
Переглядів 4,8 тис.2 роки тому
This video covers a step by step guide for explaining how the A* algorithm work, for path planning in a 2D grid map. In the following videos, I will cover D*, LPA*, D*-Lite, RRT, RRT*. GitHub link: github.com/hanmmmmm/robotic-p... For the H cost, I am using Manhattan distance since it is easier to compute by hand. For other methods for computing the distance, check this video: ua-cam.com/video/...

RPLidar A2 | Hector mapping | ROS
Переглядів 2,5 тис.3 роки тому
This is a demo using RPLidar and Hector mapping for 2D mapping. Only Lidar is used. No IMU used. I was handholding my heavy laptop and lidar, and walking inside the building. The mapping section is speeded up. Music in this video Song calm background music I use in my vlog montage (*FREE* no copyright) Artist Anna Aying

google cartographer SLAM with Velodyne Lidar
Переглядів 6 тис.5 років тому
This is a demo of using Google Cartographer SLAM indoor. The first part is using 2D algorithm with 2D Lidar data and the second part is running 3D algorithm with 3D data, but in rviz, I can only visualize the 2D map being built. It needs some more steps to get 3D X-ray style map. The 2D part is running in real-time, and the 3D one was running with a recorded rosbag.

    why do you take into the account the diagonal neighbors, but when estimating heuristic to the goal, you don't take diagonal paths?

    How do you decide the parent of a cell?? Im confused about this. Why did you decide for B1 to have C1 as a parent and not C2?

    • @MrDummyKicker
      @MrDummyKicker Місяць тому

      its how you setup the node connections in the beginning. Usually you as the programmer will determine which nod is the parent

    • @rg99999
      @rg99999 17 днів тому

      Shouldn't you take the closest node as a parent

    I set the cost to be 10 in the movements in up/down and left/right directions, and the cost to be 14 in diagonal directions. Their more precise values would be 1 and sqrt(2), but I think using integers 10 and 14 would be helpful for code running speed.
