I am thinking of getting a iRobot Create or a Roomba for a project which requires some no-so-bad odometry. I have gone through this thread and I have also noticed the following comment on turtlebot_node/roomba_sensor_handler.py
114 # The distance and angle calculation sent by the robot seems to 115 # be really bad. Re-calculate the values using the raw enconder 116 # counts.
If I get a iRobot create I will get only the distance and angle which 'seems to be really bad' since iRobot create does not give out raw encoder counts.
I would like to know if this is still the case ? I prefer iRobot create since it is inexpensive and I don't need the vacuum function. Furthermore, It would be great if any of the users can give me some quantitative values on the odometry errors.
p.s: Calling up iRobot support did not help at all :(
