Hi, I'm trying to run the teleoperation node to move a turtlebot waffle pi. It was working until few days ago, but now it doesn't.

The problem is that when I run roslaunch turtlebot3_bringup turtlebot3_robot.launch

The USER1 led light starts flashing orange. This was something that was not happening before.

I tried both with the teleoperation node, as well as publishing geometry_msgs/Twist on the cmd_vel topic.

I was thinking at a hardware connection problem, but if I flash the ROS2 firmware for OpenCR and publish the velocity commands using the ROS2 node, everything works fine.

Do you have any idea why ? Thanks

Hello :)

The USER1 led shows state of data transfer between SBC and OpenCR. This is toggled when you launch turtlebot3_robot.launch file. So your case is not problem.

I recommend that you can check Dynamixel ID using turtlebot3_setup_motor

Hi, thanks for the reply! I followed the instructions and I was able to run the tests (the motors were moving).

I noticed a strange behavior: apparently ANY ros node on the turtlebot doesn't receive messages.

If I run on my pc

rostopic pub -r 10 /cmd_vel geometry_msgs/Twist  '{linear:  {x: 0.1, y: 0.0, z: 0.0}, angular: {x: 0.0,y: 0.0,z: 0.0}}'

Then I run on the Raspberry

rostopic echo /cmd_vel

No messages are received!

Note that if I run the opposite (publisher on raspberry, listener on pc) everything works. I tried to run the ros master both on the pc as well as on the raspberry and the results are the same (messages received only when the publisher is the raspberry)

Do you have any other idea ?

I recommend that I attached check list.

1. Network configuration http://emanual.robotis.com/docs/en/platform/turtlebot3/raspberry_pi_3_setup/#5-network-configuration

2. Test by RC100 controller http://emanual.robotis.com/docs/en/platform/turtlebot3/teleoperation/#rc100

3. Test using Rqt http://wiki.ros.org/rqt

Hey did this ever actually get resolved?

I'm having the exact same issue and it was working perfectly yesterday.

Any help would be appreciated : )
