2012-02-21 15:15:57 -0500	commented answer	How to use a gps to generate a map i am able to get the odom by using the gps_common utm_odometry_node.. But the value is not stable..

2012-02-17 03:44:59 -0500	asked a question	How to use a gps to generate a map I was wondering, if its possible to use the /odom(obtained from converting lat and longitude from gps) to generate a map. Am using a Xsens mti_g device. Using cyphy lab ros driver Converted the lat and log using gps_common/utm_odometry_node Regards, AJ

2011-11-23 19:13:31 -0500	answered a question	Gyro and Odometry Calibration Not Effective? I tried to follow the tutorial and the dynamic reconfigure method. What both of them did was they changed the values of both ros parameters... Seeing this had no result, I tried to echo rostopic "/turtlebot_node/parameter_descriptions", the values were not changed. But it was modified under "/turtlebot_node/parameter_updates", but there was no effect of the calibration. The method seems to be ineffective. So I tried to find out, which file is setting the value when the node starts. The file was : /opt/ros/diamondback/stacks/turtlebot/turtlebot_node/src/turtlebot_node/cfg/TurtleBotConfig.py I modified the correction values there. This method helps in changing the correction values. But my gyro calibration is still wrong. It got better from last time. But still, I cant get a good result. Anybody has any clue on this ?
