Turn your Neato vacuum into a ROS robot using a Raspberry Pi. This project contains the code and instructions to run ROS the Raspberry Pi, setup ROS, and install the ROS node to control the Neato robotic vacuum. The code includes the ROS Neato node that communicates to a Neato vacuum using the USB port and the neato-driver-python.

no gui.launch #1

Open cyberbilly opened 2 years ago

cyberbilly commented 2 years ago

Everything seems to work up to roslaunch neato gui.launch. which yields "RLException: [gui.launch] is neither a launch file in package [neato] nor is [neato] a launch file name The traceback for the exception was written to the log file"

Index of file:///home/bill/catkin_ws/src/neato-ros/neato/launch/include/ does not show any gui.launch.

@cyberbilly I can take a look at it next week. I took a look on my phone and don’t recall if that launch file was supposed to be included in this code or pulled in from somewhere else.

I found that /home/bill/catkin_ws/src/neato-ros/neato/launch/include/ did have a Display.launch and that worked, Once I figured out that your instructions did not cover installing rviz.

Next problem I think is actual communication over usb. I can communicate fine using a serial communication app with /dev/ttyAS0 and in /dev there is symlink to "neato" as per instructions. But base.launch fails. I will investigate that and let you know. the error is:

Okay so python doesn't come with serial so needs to be added by "sudo apt-get install python3-serial"

Then /dev/neato and linked /dev/ttyACM0 need 777 permissions.

These probably need to added to your most excellent instructions. Along with how to set up keyboard instead of joystick. I have not figured that out yet....

next problem display launch yields: ERROR: cannot launch node of type [robot_state_publisher/state_publisher]: Cannot locate node of type [state_publisher] in package [robot_state_publisher]. Make sure file exists in package path and permission is set to executable (chmod +x)

I have to break, I'll look into this and let you know.

cyberbilly commented 2 years ago

problem was robot_state_publisher/state_publisher should be robot_state_publisher/robot_state_publisher. that's correct but node is already created in neatobase. So I deleted line out of neatobase.

Seems to be working now... cheers!
