Hi Tomas,
I had a delay problem with a Pioneer 3AT and a Sick LMS 200. I tested the functionality
of a serial/usb cable to the connected port by using additional software to ROS sickwrapper
such as ARIA demo program or Player driver.
My specific problem was that the initialisation time on some Pioneers (2 and 3)
takes about 20s. The driver assumes to be on request but it takes a time. I
did a simple hack to the code of the sick wrapper for re-asking to connect
after 20s.
We have the following discussion about it:
http://comments.gmane.org/gmane.science.robotics.ros.user/5555
And a ticket was created for updating the driver:
https://code.ros.org/trac/ros-pkg/ticket/4138
Perhaps that would help your sick to be on and working in the meantime.
Cheers,
Renato.
Hi everyone,
I'm trying to use ROS with a Pioneer 3-AT, with a SICK LMS200 mounted at the
front. For some reason, I can't connect to the laser via the serial port.
Even simply using the sicktoolbox without ROS is not working. The robot has
ubuntu 8.04 installed. I've tried the ports ttyS 0-3 (which is the highest
numbers they go to) and I've tried different baud rates on them all. From
what I can tell, a baud rate of 38400 is the one that the sick is designed
to work with.
If anyone has successfully run the configuration I am using, or has any
ideas about what the problem may be, I'd really appreciate some help.
Cheers,
Tomas
