Error!

[RedstoneGithub]

Hello! I want to run my iRobot Create 2 with my Ubuntu Computer that is running ROS Kinetic 16.04 (with maybe a Raspberry Pi 3 in the future) but have had very bad luck. But when I came across AutonomyLab, I gave it a shot. And it kinda worked, but I got this error:
ERROR: launch node of type [ca_driver/ca_driver]: can't locate node [ca_driver] in package [ca_driver]
I don't know why it's doing that, but any help is appreciated. Thanks!
I just started using ROS and my iRobot Create 2 a few days ago, so I don't know a lot.
EDIT: Here's my CMakeLists file:

cmake_minimum_required(VERSION 2.8.3)
project(ca_driver)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  std_msgs
  geometry_msgs
  nav_msgs

)

find_package(Boost REQUIRED system thread)

set(libcreate_PATH "${CATKIN_DEVEL_PREFIX}/src/libcreate/")

include_directories(
  ${catkin_INCLUDE_DIRS}

  include

link_directories(${libcreate_PATH})

target_link_libraries(ca_driver
  create
  ${catkin_LIBRARIES}
  ${Boost_LIBRARIES}
)
add_dependencies(ca_driver libcreate)

Edit 2: Bump! I don't see why this is not working, it should be, right? I tried everything from sourcing stuff do trying to rosrun the node which I don't know how to do!
Edit 3: Aha. There is nothing in ~/my_catkin_ws/devel/lib/ except for pkgconfig. And there was no errors running catkin build when I first built it, but now I can't catkin_make it.

[lucbettaieb]

After you catkin_make, do you see an executable inside ~/your_catkin_ws/devel/lib/ca_driver?

[jacobperron]

Were there any errors compiling (running catkin_make or catkin build) ?

For the future, I think troubleshooting questions like this are best asked on ROS Answers.

[RedstoneGithub]

Thanks for the early replies! I don't even see ca_driver in my devel/lib folder in my create_ws and catkin_ws folders. I think more than likely there were no errors compiling catkin build.

[RedstoneGithub]

I made another catkin_ws but this time I used catkin_make. I now see an executable inside devel/lib/ca_driver! I'm going to try to see if it works.

[RedstoneGithub]

In my new catkin_ws, I get a new error:

I also did post it on http://answers.ros.org/question/236849/how-do-you-use-the-irobot-create-2-a-ros-laptop-running-kinetic-and-a-kinect-v1-together/ a few days ago, but now I know what driver to use.

[jacobperron]

It looks like it can't open the serial port. Before running the driver:

1. Ensure your computer is connected to the Create with the 7-pin serial to USB cable.
2. Determine the correct serial device.
   • Run ls /dev before and after connecting the USB cable to your computer. You should see a new device in the list after connecting the cable (e.g. ttyUSB0).
   • Modify the file create_2.launch to set the correct device.
3. Make sure you have permissions to access the serial port.
   • If you already haven't run the command before: sudo usermod -a -G dialout $USER, then logout and login again.

Also, note that the square brackets in the command signify optional parameters. I.e. roslaunch create_2.launch desc:=true and roslaunch create_2.launch are valid, but not roslaunch create_2.launch [desc:=true]

[RedstoneGithub]

Thanks for the quick reply. I'm so stupid. I didn't plug in the serial cable! After plugging it in, I ran roslaunch create_2.launch [desc:=true] [publish_tf:=true] after sourcing which I always forget to do (many of my problems) and the orange LED on the Create Serial Cable is blinking and on the terminal it says,

But I'm sure after I follow @jacobperron's instructions it should work. Thanks guys!

[RedstoneGithub]

Yep, it sure is! Now, I have to run rviz with this... I will try!

[RedstoneGithub]

How exactly do you run rviz on this? And also, I can't run the joystick teleop because:

ERROR: cannot launch node of type [joy/joy_node]: joy
ROS path [0]=/opt/ros/kinetic/share/ros
ROS path [1]=/home/--/test_ws/src
ROS path [2]=/home/--/turtlebot/src
ROS path [3]=/opt/ros/kinetic/share
ROS path [4]=/opt/ros/kinetic/stacks

[lucbettaieb]

If the node is running, you should be able to type rosrun rviz rviz and select the topics you would like to visualize.

Looks like you may not have joy installed. Do sudo apt-get install ros-kinetic-joy.

[RedstoneGithub]

Thanks for quick reply, now it says
ERROR: cannot launch node of type [joy_teleop/joy_teleop.py]: joy_teleop
and for RViz I also tried that before but not much topics were showing. I tried again and still same thing. I will try to take a screenshot. But I did roslaunch create_2.launch [desc:=true] [publish_tf:=true] which worked but I did not get many topics in RViz. I also don't know how to send move commands to the Create 2, I tried before but got an error but I don't really worry about that right now.

[lucbettaieb]

Install joy_teleop the same way you installed joy. Not sure about RViz. Maybe not everything is supported yet.

Generally if you do not have a ROS package, you can install it by doing sudo apt-get install ros-<distro>-<name>-<of>-<package>

[lucbettaieb]

^Looks as if you're doing everything correctly. RViz just can't visualize everything. Try adding a RobotModel manually.
