I've been thinking lately that they need a 3d scanner and some kind of cad software to do measurements. That could take the human element out of using a calipers.

This is a completely valid point.

Even if you had a device that could throw several different molds with exactly the same parameters (e.g. initial velocity, pitch, yaw, roll angles, etc), it might only be of limited use if the way people throw discs is different from the way the machine does.

Obviously, the goal would be to make the robot throw the same as a person. But therein lies the problem, because: What does a person throw like? and who's the person? I doubt I throw like Hampy, or he throws like you. The algorithms you'd need to develop to be able to simulate throwing like Paul, Seppo, Ricky, Paige, Joe Am 1, Robby Rec, Nicky Newb... would likely be mind boggling. What about sidearm? How many players have Sarah Hokom's form?

- Disc rotation speed (snap) can be regulated thru the RPMs of the wheel.

The only thing really missing is the arm speed and those mechanical movements.

Even if the throwing machine doesn't mimic a human throw, at least it would be able to consistently repeat a throw with the same disc.
I.E. you launch a Roc indoors on a turf field and the next Roc you launch lands within a foot or so of the first.

^^^thats really the point, to measure flights of discs vs others.

Then you could see the difference-what really is the flight difference of a PD vs Thunderbird vs Anax vs etc
Later then, more glide, etc etc all could be determined if the throw is identical, every time. Doesn’t have to throw like Seppo/Paul/Simon, it would just have to throw within the normal human range of speed and spin. Once the disc is in the air, with its rotation, speed, nose angle, and trajectory determined, it wouldn’t matter what the form is because it could compare discs against eachother without the human factor

We can build robots to assist with highly critical surgeries, we can build highly complex robots to completely run a massive manufacturing facility completely lights out.....I'm pretty positive that we can build a robot to chuck a piece of plastic.

I know of at least one throwing machine being developed along the lines of the one shown in the video clip above. They've discovered some technical issues that need to be worked out to make it more closely simulate golf throws. No idea on timing.

Sounds good in theory. Problem is, discs are inconsistent enough that I'm not sure you could get a stack of PDs to fly like other PDs (what run? plastic? plh? etc)

I disagree. If I was using a robot to decide which disc to buy, I would want the robot to throw the disc the same exact way each time: flat and level. The only parameter I would want adjusted is the disc velocity (mph). This way I could easily understand it's flight path and decide how over/under stable the disc is.

I don't see the point in this at all really. Hamp has already made a lot of good points..

But, yeah its possible. Clay pigeon throwers have been around for a long time.
