Hello,

I have a robot daNI and I am using the dead reckoning mapping system on it. It is available on the NI site. I am trying to build a path for the robot. Basically the small dot on the map would leave a line behind. This is to see where it went. I tried feeding back the information of the position to the initial position but it dod not work. Does anyone have any idea why?

Thanks

Try this link, it is about finding the position using the wheel velocities https://decibel.ni.com/content/docs/DOC-17273

yea I am using this one. But it is only showing a XY grid with a dot on it. The dot moves on the grid as the robot moves. I want the dot on the grid to leave a line behind it in order to build a path of the of where it goes.

Hi N3utrin0,

Looking at that example VI, it plots the instantaneous position (both estimated and actual) on an XY graph.

To display the path that's been taken, you'll need to find a way of retaining that information, so that it's constantly displayed on the graph.

Alternatively there's a lot you could do with a 2D picture control to draw out the path.

I've written and attached an example using a 2D picture control to retain a path defined by X and Y movements. This should be relatively easy for you to integrate into the robotics example.

Let me know if this is helpful, or if you get stuck.

Kind regards,

Hi N3utrino,

I've managed to cobble together a quick example of what I meant (See attached).

It's crude but it should be nearly there in terms of what you want. 

Kind regards,

Oh, just noticed you marked my last post as solved! Thanks a lot!
