What next? Installed ROS on my pi


Looking for some more help. sorry... I have now installed ROS on the Pi and its connected to the network. I'm sure im missing something however in relation to Marty.

I have since found: https://robotical.io/learn/article/Deep-Dive%20with%20ROS/Practice/

Things you'll need

I have cloned the two packages into ROS (src directory) but not sure where to go from here...

Any help would be great!!!!

Hi there!

Sorry for the slow reply, lots of plates spinning at the moment!

Getting ROS + openCV + our packages installed from Scratch really does take a while! Then there are some complications with using serial on the Raspberry Pi 3 which need to be tweaked too... It's much easier if you have a spare microSD card to download our Raspberry Pi image which already has all that stuff on it!

I think we need to put together a more specific set of instructions (or maybe just a script!) for installing it all from Scratch - but for now if you could use the image that would be much easier! ;-)

I've also just made a forum post that details how to get started with the pi image - just skip over the camera-ey bits if they're not useful to you!

All the best,

After more investigation I think I have a problem with dependancies. The tf2_ros ins't present and looking at it on github I feel like I'll be going down a long path of getting all those installed. Please help :)

I'm now a bit further on but still have issues...

So I have cloned the two packages into the src directory and tried to

Resolved dependencies: rosdep install --from-paths src --ignore-src --rosdistro indigo -y -r --os=debian:jessie

This threw and error:

ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: ros_comm: No definition of [roslisp] for OS [debian] ros_marty: Cannot locate rosdep definition for [marty_description]

then i tried


and this threw the error below when it got processed ros_marty. I gues I'm not installing properly??

-- +++ processing catkin package: 'ros_marty' -- ==> add_subdirectory(ros_marty) CMake Warning at /home/pi/ros_catkin_ws/devel/share/catkin/cmake/catkinConfig.cmake:76 (find_package): Could not find a package configuration file provided by "tf2_ros" with any of the following names:
