Disk Gripper
 

We are thinking about building an arm with a gripper that supposed to collect the disks from the ground (as 2056, 67 and many more did last year with the balls). Someone have any ideas for the gripper? We want to catch the disks easy and fast, and it would the best if it we could the disk while the robot is moving.
We tried to use a roller gripper, but it can't lift the disk above the ground ( because the disks are flat and tough).
Thanks

Our tests have shown that some kind of thin, slippery, flexible scoop works well for getting under the Frisbee to assist a rolling mechanism to pick it up. If the coefficient of friction between scoop/Frisbee is a lot less than the coefficient of friction between carpet/Frisbee, it slides under the Frisbee quite easily.

An arm with a gripper that should work while the robot is moving is just getting asked to get ripped off by another robot. But while you are on the topic, perhaps a three-clawed gripper (two claws towards the rear side of the bripper and a movable claw to the front that pushes the frisbee against the two other claws) might work. The former two claws should be fixed and the three claws should be spaced equally around the frisbee when it closes.

We tried to grip the disks it is not easy to catch it is Sliding
The quotation is who many disks you can catch in 2 minute ؟؟؟؟؟

Leftover regolith from 2009 works great. Just round off the leading edge and be sure to make plenty of spares - its not the toughest material out there. However, it is very thin, very slippery, flexible, and perhaps available in your storage area.
