The green dots show the start and end goal, the red lines show the path taken by the robot.Ī video showing the robot in action (running in Player/Stage) is below. The black dots define the boundary of the map, the red and blue boxes are obstacles, and the cyan dots are nodes in the GVG, constructed based on this map. Example output from the program, plotted in Matlab. WoWMatrix doesn't show the author's description of an addon anywhere.

This means that users who download an addon through their program have no way to give feedback to the author, or report problems they may encounter.

This is still in progress, but the code is functional in the meantime. WoWMatrix doesn't show an addon's real download URL anywhere. I’ve since added the code to github and started cleaning up the files so that they’re easier to understand and reuse (refactoring, adding tests, etc). I completed this project during a class for Joel Burdick while an undergrad at Caltech.

It requires a full map of the environment in order to navigate. Voronoi-bot is a robot that navigates by creating a Generalized Voronoi Graph (GVG) and then traveling along this graph to reach the goal. In the meantime, enjoy this video of the above scene, from the robot’s point of view! Using OpenCV + ROS to find an orange traffic cone, and using this feedback to “capture” the waypoint.Our attempts to use the move_base stack with hobby-grade sensors, and why we ended up writing our own strategy node.Localization in ROS using a very, very sparse map.
Using robot_pose_ekf for sensor fusion of IMU + wheel encoders to allow us to navigate using dead reckoning The main reason for macros not working in WoW is a faulty script/syntax.Over the next few weeks, I’ll be writing more detailed posts about the robot and specific challenges we faced, including:

Paul, MN, which was a blast and greatly expanded our knowledge of the software and what it was capable of. We were even able to attend the very first ROSCon in St. Our software platform was ROS - rospy specifically - and we made liberal use of various components in the navigation stack. Note the red-orange potters and yellow plastic bin–“red herrings” that our robot is wisely ignoring!įor our platform, we used a modified version of the CoroWare CoroBot, with additional sensors like ultrasonic rangefinders, a 6-DOF IMU, and wheel encoders. To give you an idea of what this looked like for us, here’s a picture of us testing in Bill’s backyard: Our robot moving between two waypoints. Robots have three opportunities to navigate from a starting point to an ending point and are scored on time required to complete the course with opportunities to lower the score based on contacting intermediate points.īasically, we had to develop a robot that could navigate around a campus-like setting, find GPS waypoints marked by orange traffic cones, and do it faster than any of the other robots entered. Robo-Magellan is a robotics competition emphasizing autonomous navigation and obstacle avoidance over varied, outdoor terrain. To steal the description directly from the website: This summer, my friend Bill Mania and I entered our robot in the ChiBots SRS RoboMagellan contest.
