		<description><![CDATA[I am new to KARTO. After installation, we have several examples to use, e.g. 'intel'.
But the problem is after i load those maps, i cannot use mouse dragging to move the map. Moreover, all the test functions like mapping or exploring remain grey in the menu bar. I cannot click them to have a try.

What is wrong with that?
Thank you]]></description>

		<description><![CDATA[Hi, I have downloaded Karto trial to use with MRS. And I have some problems running just the tutorials. The error say something like it can't find the assemblies "simulateddifferentialdrive" and "interpolator". If you can help me please.. I don't know if i don't have some reference somewhere or... Thank you!]]></description>

		<description><![CDATA[Dear Karto

How accurate is the localization( deviation to the true position ) after travelling around 100m in a building ?

Thanks a lot

		<description><![CDATA[Dear support,

Is karto able to recognize and update dynamic changes in the map. for example:in a room, a door was openend after one hour. 
Some SLAM algorithm visualize both states. The door will be shown closed and opened. 

Is it able to visualize fast moving objects like humans?


thanks a lot]]></description>

		<description><![CDATA[I have a robot with a terrible odometer and I am trying to make a map of a hallway using Karto. After adding each scan I compare the odomoetry my robot thinks and what Karto thinks, and it is always the same (I am comparing the two poses I passed into my LocalizedRangeScan after AddScaning them to the Mapper). Why is this happening, shouldn't Karto be correcting for bad position information?]]></description>

		<description><![CDATA[Karto seems to do very well in nicely structured environments, such as office hallways. However, its default behavior in less structured settings, such as a parking lot or a large lab, yields maps which are much worse than we get from our raw odometry.

What parameters would you suggest tuning in order to realized better results in such environments?]]></description>

		<description><![CDATA[1) I have a map of an empty static world. My robot is going to be operating in this room when there are people in it. What is the best way to use karto to path plan / move around people? Should I use the Localization or Mapper module

2) I have a known map of a world and I am trying to load the map into the Localization Module (using ReadOccupancyGrid("mapname") and then SetOccupancyGrid). When I call SetOccupancyGrid, I get the error "Unable to calculate probability grid". What should I do?

Thanks]]></description>

		<description><![CDATA[Can Karto's scan-matching algorithm update its parameters dynamically? Say, for instance, our robot is navigating narrow corridors and then enters into a large open space, such as a lobby. In this case, it might make sense to dynamically increase the RangeThreshold to maintain performance of the scan-matching algorithm. Is this possible? Is it recommended - or heavily advised against?

Thanks!]]></description>

		<description><![CDATA[I've been using the localization module with my own png map and log file. The log file was generated using data from Cogmation's robotSim. There are no problems reading the data but I get an error once localization starts--assertion failed in ktlocalizer\probabilitygridmodel. I feel that the problem could lie in my pose input. Does the z axis increase as you go down or up the map? ]]></description>

		<description><![CDATA[Dear Karto,

I have a mobile robot with a SICK S300 professional laser scanner. I am currently evaluating Karto for mapping with this robot.

The accuracy that I am able to get with the global MCL localizer is about 20cm in the best case. Also, it is able to localize correctly only if the robot is placed somewhere in the path which it followed while making the map. It does not recover from the wrong hypothesis.

I read that your implementation is based on the MCL localizer described in the book by Sebastian Thrun. It was mentioned that they introduce random particles to tackle the problem of converging to a wrong point. Is this available in Karto? If so, how do I use this feature.

It would be very helpful if you can suggest some measures to tackle this problem.

regards,
Nikhil Somani]]></description>
