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.

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.
