2019-06-01 00:58:30 -0500 | marked best answer | OpenCR Board Can't Publish, Can Subscribe (WSL) Hello, Lately I've been trying to follow the tutorials at the robotis manual to learn about ROS and Turtlebot3. I have a Turtlebot3 Burger. My setup
QuestionWhile trying to get SLAM to work, I was experiencing a common issue of no transform from odom to base_footprint. Upon more investigation, I found that I couldn't see any odom data through However, I know that I can command the turtlebot using keyboard teleop. I just can't receive any messages that are sent "from" the OpenCR board. Why is this? I have explored the idea of this being a time-sync issue. I have checked to make sure my ROS_MASTER_URI and ROS_HOSTNAME are correct on all machines. Any help is much appreciated. Thank you. --EDIT 0: This doesn't seem like a cross-computer issue to me, but rather something with rosserial that is causing topics to not have messages published.-- EDIT 1: actually, it is a cross-machine issue! EDIT 2: When I use EDIT 3: I am able to publish from RPi to PC and vice versa, but nothing comes from the rosserial_python node. |
