Problem installing roomblock

[RomanROBER]

I am new to ROS and Ubuntu. Thank you for the tutorial but Im having trouble installing the roomblock, when I run ./install_roomblock.sh I got this error :

Im running Ubuntu Mate 16.04 on a Raspberry 3 B+ and have ROS Kinetic. Is there any Troubleshooting for this issue?

I don't use Ubuntu Mate, but I have encountered similar problem. Some binary in libraspberrypi-* conflict other system packages. In general, you can avoid this as:

$ apt download libraspberrypi-bin-nonfree
$ sudo dpkg -i --force-overwrite libraspberrypi-bin-nonfree.deb

I expect someone on upstream solves this problem eventually.

Hello again, I tried your solution but now I got another Problem:

Thank you very much for your help

Please specify the file (libraspberry-pi-bin-nonfree_1.2brarabra.deb) you just downloaded.

[RomanROBER]

You were right :)

I had some trouble with rtl8192cu driver and with the kernel so I installed everything separately

Then I ran the installer again and it prints that is installed then I did:

$ sudo apt upgrade
and reboot

So now when I try to run roomblock_bringup roomblock.launch it shows that is not installed or found.

The install script doesn't create workspace and get the source code.
Please consult README.md to create your own workspace, get the source code, and build it.

$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src
$ git clone https://github.com/tork-a/roomblock.git
$ cd ~/catkin_ws
$ rosdep install --from-paths src --ignore-src -r -y
$ catkin_make

Many thanks for the help!

now I made the Workspace :

But when I try to run :
$ roslaunch roomblock_bringup roomblock.launch

I got :

Am I missing something else?

You need to source setup.bash to use the workspace.

cd ~catkin_ws
source devel/setup.bash

And I strongly recommend to take a look on ROS wiki to get basic concept of workspace and packages.

Thank you for the fast answer and for the suggestion this is my first Project with ROS. I will read and practice more.

Now is working but can I use the roomblock with the Serial Port (ttyAMA0) instead of the USB cable?
I have my Roomba connected to the Serial port.

I haven't tried it yet. I believe there is no difference between usb serial and on board serial. I'm grad if you try it.

Edit this file to change the port from /dev/roomba to /dev/ttyAMA0.

roomblock_bringup/launch/include/real_roomba.launch.xml

Or making a symlink from your device file to /dev/roomba may be easier.
