Slam gmapping problems
Hello all,
Trying to do some mapping with a corobot Explorer robot. I have here the terminal output: hmt@hmt-snowball:~/roscorobot-code/Corobot/corobot_teleop$ rostopic list /PTZ/camera_info /PTZ/image_raw /PTZ/image_raw/compressed /PTZ/image_raw/compressed/parameter_descriptions /PTZ/image_raw/compressed/parameter_updates /PTZ/image_raw/theora /PTZ/image_raw/theora/parameter_descriptions /PTZ/image_raw/theora/parameter_updates /PhidgetMotor /REAR/image_raw /bumper_data /camera/set_state /camera/set_videomode /camera_info /diagnostics /fix /gripper_data /hokuyo/parameter_descriptions /hokuyo/parameter_updates /image_raw /imu_data /infrared_data /kinect/depth/image_raw /kinect/rgb/image_raw/compressed /odometry /pantilt /phidget_info /position_data /power_data /rosout /rosout_agg /scan /sonar_data /spatial_data /ssc32_info /takepicture /tf hmt@hmt-snowball:~/roscorobot-code/Corobot/corobot_teleop$ rosbag record -O mydata position_data tf scan odometry hmt@hmt-snowball:~/roscorobot-code/Corobot/corobot_teleop$ rosbag play mydata.bag Waiting 0.2 seconds after advertising topics... done.

So, as can be clearly deciphered, I recorded a bag file with the /tf and /scan topics. So, how do I use the gmapping utility to generate a map by playing the bag file?
Thanks, -Hunter A.
