Hey there,

I have a roomba version 521 and I would like to use it as base of a "turtle Bot". I know this is kind of old stuff cause no one uses these base es anymore. Many use kobuki or directly start with TurtleBot version 3.

Nevertheless I would like to use a roomba version 521 as the base staion of my turtlebot. Now I am searching for software to connect this base station via a Mini - DIN serial port connector to a laptop on which ros indigo 14.04 LTS is running on.

My Problem is I do not find any working software for communicating with ros with my laptop to the roomba. I ended up with this tutorial: wikiRobots/RoombaRobin.

When I tried to test the software I downloaded within this tutorial. And I started:

roslaunch roomba_robin_bringup minimal.launch

I got the following errors:

roslaunch roomba_robin_bringup minimal.launch ...
logging to /home/markus/.ros/log/65038936-b274-11e6-8df8-9cb70de7f81a/roslaunch-turtleBot1-6333.log

while processing /home/markus/catkin_ws/src/roomba_robin/roomba_robin_bringup/launch/includes/mobile_base.launch.xml:

u'/home/markus/catkin_ws/src/roomba_robin/roomba_robin_bringup/launch/includes/kobuki/mobile_base.launch.xml'
The traceback for the exception was written to the log file

Any ideas how I can solve this issue?

By the way if I connect my serial cable with the laptop and type lsusb I see the following:

Bus 003 Device 006: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

Hope if somebody knows where there is still software for the roomba 521 available?

WIth the Tipp of Jacob: Thanks Jacob,

I saw that you have one of the biggest libraries for the Roombas and I already testet it... I followed your tutorial on your Page step by step but I came into some problems when executing

roslaunch ca_driver create_1.launch [publish_tf:=true]

Hi Markus,

You could check out my driver create_autonomy for controlling the Roomba base as a replacement to roomba_robin. The create_1.launch file should do the trick.

catkin is not detecting any packages. Is the create_autonomy repository actually cloned inside catkin_ws/src ? Also, the square brackets [publish_tf:=true] are to indicate it is optional, meaning you shouldn't actual type those. You can just run roslaunch ca_driver create_1.launch.

Hm I fixed that issue now. However I get a new Problem when executing> roslaunch ca_driver create_1.launch
It says the following> Unable to contact my own server at [ http://130.83.118.240:32925/ ]. This usually means that the network is not configured properly.

After solving this error I would like to know how do I use: rostopic pub power_led std_msgs/UInt8MultiArray 1 2 the above code is not workin what do I have to change

You might find rosrun rqt_publisher rqt_publisher easier to use. I'm not sure of the proper command line syntax.

As far as network issues go, I would ask around other threads. See http://answers.ros.org/question/23644...

The command line syntax is:

rostopic pub -1 /set_ascii std_msgs/UInt8MultiArray '{data:[34,35]}'

rostopic pub /power_led std_msgs/UInt8Multiray '{data:[90]}'
