Error when running turtlebot3 bringup

[alvinisheree]

Hi, following the steps in bringup a turtlebot3, I am currently stuck with this error:

I was able to solve this error by changing the USB cable connecting raspberrypi and lidar board yesterday. However after turning on turtlebot3 again, this error cannot be eradicated and I cannot seem to find out why. Please help. Thank you.

Hi :)

Can you test that catkin_make again after remove devel and build folder? (Need source ~/.bashrc command)
And launch turtlebot3_lidar only not turtlebot3_robot

[alvinisheree]

Hi there!

Sorry I don’t really understand as I am still kind of new to this.. do you mean to execute this command?
$ cd ~/catkin_ws/
$ rm -rf src/ build/ devel/
$ mkdir src
$ cd ~/catkin_ws/src
$ git clone https://github.com/ROBOTIS-GIT/hls_lfcd_lds_driver.git
$ git clone https://github.com/ROBOTIS-GIT/turtlebot3_msgs.git
$ git clone https://github.com/ROBOTIS-GIT/turtlebot3.git

Input command:

pi@raspberrypi:~ $ cd /catkin_ws/
pi@raspberrypi:/catkin_ws $ rm -rf build/ devel/
pi@raspberrypi:/catkin_ws $ source /opt/ros/kinetic/setup.bash
pi@raspberrypi:/catkin_ws $ cd ~/catkin_ws && catkin_make -j1

catkin_ws build was successful with no errors.

Input code to launch lidar:

pi@raspberrypi:~ $ roslaunch turtlebot3_bringup turtlebot3_lidar.launch

Sorry for inconvenience, Can you please test it without ROS?
I give you a reference how to run it

Hi, I was able to solve the problem by changing the cable connecting LIDAR to Raspberry Pi.
Now I am currently stuck with another problem at step 9, SLAM. When i ran this command:
roslaunch turtlebot3_slam turtlebot3_slam.launch slam_methods:=gmapping in RVIZ, I am unable to see any image produced by LIDAR where the status says "No image received". Do you know how to solve this issue? Please help thank you.

[alvinisheree]

This issue persisted even at step 11: Simulation where i ran turtlebot3 simulation in gazebo and after launching command to open RVIZ: roslaunch turtlebot3_gazebo turtlebot3_gazebo_rviz.launch the camera does not display any image as well. Is there something wrong with my currently installed RVIZ package or is there problem somewhere else. I tried googling around but couldn't find any solution for this problem.

[routiful]

Sorry for late reply.
TB3 burger doesn't have a camera. If you want to show image, you are supposed to install camera on your TB3.
