Good night partners

I would like to use an usb camera (common usb camera) on my raspberry pi running groovy-raspbian.

I've just followed the instructions in

http://wiki.ros.org/ROSberryPi/Setting%20up%20ROS%20on%20RaspberryPi#ROS_Peripherals

At step 4.1 when I finally type roscd usb_cam I have the following:

roscd: No such package/stack 'usb_cam

Where am I wrong? Where is my mistake?

Thanks you so much

EDIT1 : I have also downloaded this https://github.com/bosch-ros-pkg-release/usb_cam-release/releases/tag/release%2Fgroovy%2Fusb_cam%2F0.1.3-0 but I'm not sure if it will help me. I don't really know how to proceed with this.

You need to make sure that usb_cam is in your ROS_PACKAGE_PATH so that the package can be found.

First of all thanks son much for your interest.

When I type rospack profile I´m given the next:

Full tree crawl took 0.390944 seconds. Directories marked with (*) contain no manifest. You may want to delete these directories. To get just of list of directories without manifests,

re-run the profile with --zombie-only

If I type echo &ROS_PACKAGE_PATH I´m given:

/home/pi/catkin_ws/src:/opt/ros/groovy/share:/opt/ros/groovy/stacks

May I have to do an export or something similar? In this case, how would be the semantics?

Maybe

export ROS_PACKAGE_PATH=/home/pi/catkin_ws/bosch_drivers/usb_cam:/opt/groovy/share ?

Sorry for my lack of knowledge and thanks you so much

EDIT 1:

I copied the bosch_drivers into my catkin_ws/src and did the catkin_make.

Now I can roscd usb_cam but when I do rosmake I'm given:

  • Configuring incomplete, errors occurred! -------------------------------------------------------------------------------} [ rosmake ] Output from build of package usb_cam written to: [ rosmake ] /home/pi/.ros/rosmake/rosmake_output-20140116-192405/usb_cam/build_output.log [rosmake-0] Finished <<< usb_cam [FAIL] [ 16.84 seconds ]
    [ rosmake ] Halting due to failure in package usb_cam. [ rosmake ] Waiting for other threads to complete. [ rosmake ] Results:

    [ rosmake ] Summary output to directory
    [ rosmake ] /home/pi/.ros/rosmake/rosmake_output-20140116-192405

And if I try rosrun usb_cam usb_cam_node I'm given :

[rosrun] Couldn't find executable named usb_cam_node below /home/pi/catkin_ws/src/bosch_drivers/usb_cam [rosrun] Found the following, but they're either not files, [rosrun] or not executable: [rosrun] /home/pi/catkin_ws/src/bosch_drivers/usb_cam/src/usb_cam_node

Could anyone help me please?
