The gas springs make the load on the system pretty well near zero unless accelerating. Aka the system thinks its close to weightless while sitting still. There is still inertia that has to be overcome but the shooter assembly as a whole is pretty well balanced. Before the lead screw was put on it would hold what ever position you pushed it to. So in short they allow us to have to go through less of a reduction in order to change the angle of the shooter which allows us to do it more rapidly.

So the ground pick-up shoots the disc up and back out of the robot, and through the chute at the feeder station back to the human player? Does the human player then drop the disc back onto the top of the robot through the high slot?
This sounds kind of inefficient, if I understand correctly.

Getting your arm "weightless" is a great idea! Well done!

lol No, if you look at the robot you will see two blue rollers not in-line with the ground pickup; those are on their own smaller arm that rotates in-line if the shooter and the ground intake. That will rotate to be in-line with the ground intake and a disc will load in and then it will realign with the shooter and push it in to shoot. That arm(we call it the flipper) is also how we load from the feeder station. It flips out and then just reverses direction to load into the robot.

On the back of the robot is a chamber that rotates between feeding the shooter as shown in the picture and straight out.

When it is straight out the back, it serves 2 purposes. It serves as a method for the HP to load frisbees into the robot, and it allows one of our stowed frisbees to be loaded in the chamber and then rotated to be fed into the shooter.

I'll find a picture that can better illustrate the process.
