2019-10-13 16:46:06 -0500 | marked best answer | How to do GMapping and SLAM Navigation using RPLIDAR A2 and Kobuki? I have a Kobuki and installed Turtlebot software on my Turtlebot laptop and set everything up for Turtlebot, and I just got an RPLIDAR A2 yesterday and I couldn't figure out how to get it to work with Turtlebot Gmapping and AMCL, to navigate autonomously. On the remote computer the scan doesn't show up but the Kobuki's odometry shows up. I dont think there were any errors. In the launch file I deleted the line of code that starts the 3d camera, and I start the RPLIDAR node from another command line. But again, nothing! So please help me if you can. I am running Ubuntu 16.04 and ROS Kinetic on the Turtlebot Laptop and Ubuntu 14.04 ROS Indigo on the remote computer. Thanks! Edit: I am now using hector_slam to do this. I have a pretty noisy map but I guess it could work, but now the question is how does the Turtlebot use the RPLIDAR A2 to navigate in the map generated by hector_slam? What parameters should I use in RVIZ? Is there a hector navigation file? Edit 2: I could still use Gmapping, and obviously that would be SO much easier since I know how to do gmapping, but how do I implement it with an RPLIDAR A2? I will edit this again when I can get the error codes. Also, the errors happen when I run the rplidar node and then the turtlebot minimal node and then the gmapping node and I think it's because of a transform that I didn't put in the launch file. |

2017-03-29 14:00:11 -0500 | asked a question | How do you make a transform for a laser and a Kobuki? What I want to do is to use "slam_gmapping" for my Kobuki robot and I'm using a Phab2 Pro as the laser scanner, because on the phone itself, it converts pointcloud to laser scans. (Phab2 Pro has Project Tango built in) But the problem is that when I select "Map" as the Fixed Frame in Global Options in RViz, I only get my Kobuki TF data and not my Phab2 Pro's TF data. I've read somewhere that it has to do with making a transform, but I don't know how to do that. Also, I need easy instructions because I'm not advanced in ROS, but I'm not new either. I'm in the middle. I will post screenshots soon, too. I am running ROS Kinetic on an Ubuntu laptop (I think 16.04; whatever the latest version is). I'm also running Tango ROS Streamer on my Phab2 Pro, then running RViz with a special .rviz file so that I can see what the Phab2 Pro is capturing in real time. The error is: |

2016-06-17 05:52:55 -0500 | asked a question | Going to get Kobuki-- need help Hello! I'm getting a Kobuki base soon (today) and I want it to navigate (using preferably RViz) using my Kinect (which works with rtabmap) so can anyone tell me drivers that might work? For now, though, I have an iRobot Create 2, which will be returned. I also have an Ubuntu laptop running ROS Kinetic. I also found a US retailer for Kobuki which is http://dabit.industries/ because of the $183 shipping from the official site from China!!!!!!!!! |

If you know about TurtleBot, scroll down to see my errors when trying to run TurtleBot. Then, when I run catkin_make_isolated I get: Then tons of more errors. I tried running it with both of the options above, but all I get is: Edit 5: I have ROS Kinetic Kame so that's probably why nothing at all is supported. I would really like some updates if TurtleBot can work with Kinetic Kame, because it's not for me!
