Hello Everyone,
When I create a path from curve and setting the minimum distance between the targets at 3, 2 or 1mm and max cord dev at 1mm, the targets generated have a distance of 5mm or more. For example, a circle with diam. of 400mm, min. dist. of 1mm and max cord. of 1mm create 70 targets (18mm between each target).
How to proceed to respect the minimum distance?
Thx

Hi,
The minimum distance parameter seems to be respected in your case. There are 18 mm between the targets which is more than the specified minimum distance of 1 mm. The minimum distance parameter is used to limit the number of targets created.

Hi,
Thanks you for the answer,
In this case, how to set the increments between targets at 1mm?
Thx,

You can lower the max cord parameter to get more points. It is a measure of the deviation between the original curve and the robot path (approximated using linear and possibly circular segments.)

Hi,
If you want an exact distance of 1mm between each target along the curve, you should use the setting “Constant”.

Hi,
I have checked in many menus and I found nothing about setting “Constant” distance between the targets. How does it possible to set this?
Thx

Hi
In RS 4 you need to write your own addin that does this. Not to hard if you know VB programming.

Unfortunately, the “Constant” option is only available in RobotStudio 5.x, not 4.0.
