Robot Positioning X and Y Co-ordinates

[patshnider]

Hi,

I am currently undertaking a project concerned with swarm robotics. We have 5 robots and a system which calculates their position within an area in terms of x and y coordinates.

The positioning system will constantly update the position of the robots and the direction which they are facing.

I am looking to try and use labview to try and show the position of these robots in real time. I was thinking of using simple shapes (rectangles) to represent the robots and these shapes could be displayed on a screen to show where the robot is positioned on the grid.

I have searched through the forums and can't seem to find anything similar.

Thanks

Would something like this help?

You can download the code used for this project at http://decibel.ni.com/content/docs/DOC-13031

Define real-time.

I would go with a picture indicator, draw the robot as a rotated triangle pointing in the direction of travel.  you can make a single subvi to draw the triangel takes a X,Y, Angle and color.  Itterate over an array of clusters with this parameter for each update.  Should be able to run this fast I wouldnt show this faster than a few hz since you will not know the difference.

Thank you for the sample code given above.

I have adapted in the way in which I would like the picture to appear.

I would now like to try and place multiple robot images on the picture as we have multiple robots in our demonstration. These robots will have different coordinates to each other.

I had thought of using a for loop which could repeat N times (with N being the number of robots) but I am not sure how to implement this.

I have attached the .vi as it currently stands.

Thanks

Something like this should work. I added a loop and arrays for your coordinates and the robot picture and color.

[patshnider]

Thanks but I can't seem to get the picture to display anything.

Did you add the pictures to the array? If you have multipule data sets you will need the same number of pictures and colors.

[patshnider]

I am not really sure what you mean. I have tried changing the inputs on the front panel but cannot get the picture to display any image when it is run.

I made a few small changes I did not make it so that you can chane the color of your robot. That will take a little more effort. I also took out the check for posture vi so that I could get it to run this time. It seems to work.

OK this one does multi colors.
