You can change this tolerance to reduce the density of points when you generate a robot program:
Select Tools-Options
Select the Program tab
Set the Minimum step size (mm)
This value is 0.005 mm by default, you can increase it to have less points.
Some CAM software create a point every 0.001 mm. This may be too much for robots so if you use a tolerance like 0.1 or 0.2 mm it should be fine for most robots unless accuracy is critical.
