Hi! Do you mean something like this? http://www.youtube.com/watch?v=KqbrWS2TY4w I was inspired by it so i built one that does the same thing, except it makes the sound by clapping its hands. It's implemented by letting timers capture the time between the beats and then add them to an ArrayList. Then...

I really love the map processors I wrote a couple of weeks ago :) This makes it so easy to write new functions to the map.

I could give you some tips what we've learned from our project this far. * Build a stable robot that doesn't spin or change course to much. * Use lejos.robotics.navigation , it makes localization so much easier * You need to transfer at least these values: ** RobotPos (X, Y) ** RobotAngle ** Distanc...

I've now implemented a generic way to process the map data. So if you wake up in the middle of the night with this great idea of how to calculate exactly where the walls are you just have to create a class that implements the interface IMapProcessor , add it to the instance of MapProcessors and you ...

Hi! As I see it's incomplete though the purpose of it is not to give you a map by auto, more likely to setup a standard of how to send maps. I'm not sure though. You can view the source for lejos.robotics.mapping here: http://lejos.svn.sourceforge.net/viewvc/lejos/trunk/classes/lejos/robotics/mappin...

@gloomyandy: Thank you! :D We are born in 1991 so we've both turned 18 this year. In the third year of Swedish Gymnasium (roughly equivalent to 4th year in high school) every student has to make a project concerning at least one of the fields he/she studies as a final project for their studies. We s...

@alai: Thank you :) It's working great and we love to be able to save and open maps so that we can playback how the robot drove. It's much easier to debug then and we are also able to develop the algorithms even if we not have the robot with us.

PenemuNXT - Exploring map bot

We have created a NXT robot which uses the OpticalDistanceSensor from Mindsensors to scan an unknown area around it. The robot will be able to navigate and stream data in realtime to a computer who will paint up a map from the data gathered by the robot. The robot is programmed using LeJOS and the s...
