Hi
I have industrial robot and position is at Point A (x,y,z) in time
t=t1. I want to pick product on the belt with speed v (t) (not
constant, can change 0-Vmax). At time t=t1 product is at position
(X1,Y1,Z1). I have trajectory between A and B at the time t=t1. How
can I calculate speed for robot or position to catch this product?
Has somebody good document about catching the product on the belt?
Thanks.
Regards
Leo

No, I need better quality of tracking operations.

Do you know the speed of the belt? If you can get the changing belt
velocity, you can integrate it forward in time beginning at t1, and that
will get you the proper position at some later time t2. The faster you can
get accurate velocity readings, the better that integrated position will
be.
If, instead of sensing it, you know the belts expected velocity profile
between t1 and t2, you could integrate that function instead to get the
expected position.

I know only position of products on the belt in every scan. The
problem is if the belt is fast, how can I reach this speed?
