Picking frisbee off the floor prototype
 

Here we have our gen 2 prototype for picking frisbees off the ground and at the end of the run we will have a pneumatically operated loader and shooter with a linear frisbee shooter. The angle of our arm is roughly 20 degrees. Our arm will also have our pyramid climber mounted on both sides of our arm.

It looks like you have to be pretty well lined up to pick up a frisbee. Have you tried a wider intake so your robot wouldn't need to be lined up so accurately?

This is prototype gen 2 there will be a gen 3 with wider opening, plus you need a good driver!

Great! My team used a wide loader at WPI's Savage Soccer in November and it was the highest scoring robot there. Wide intakes make a huge difference.

I like it. Now does the lexan piece at the end cause any problems? We tried something similar but it kept catching on the tape we put down to mark the field lines.

I am interested in knowing this answer and also if the ramp is straight or curved. Also, how does this perform on upside down Frisbees?

Nice work.:D

We didn't think about the field tape when testing this. That is something we will be sure to do tommorow. Even if it struggles with the tape though, it doesn't seem like it would get in the way to where we plan on picking up which is on our side of the field.

What about the bump of the plate that the pyramid is on? Won't it hit that?

Re: Picking frisbee off the floor prototype
 

This current design does not actually have it touching the carpet, it just looks like it does. If we stay with this, tape should not be a problem. We will test it tomorrow and post video in this thread.

Re: Picking frisbee off the floor prototype
 

we believe that 90 % of the frisbees will be right side up. We have alot of experience playing ultimate and vary rarely do they land upside down..... If they do don't pick them up...

Re: Picking frisbee off the floor prototype
 

We won't do it there, there are plenty of other places...., although the carpet is making the step a softer angle, our arm may just go up it.... not really worth it though if you have other to pick from

Could be worth the effort if you hope to pick up 2 under the pyramid during auto, Fredi ;) Nice prototype just the same! Have you tried the set up without bottom belts and just lexan bottom on long run portion of loader?

Re: Picking frisbee off the floor prototype
 

How close to the ground are you?

Re: Picking frisbee off the floor prototype
 

Once you pick up the frisbees, how will you get them into your hopper or whatever you use to hold the frisbees?

Looks great! :]

Re: Picking frisbee off the floor prototype
 

We haven't tried without belts on the bottom, but honestly the polycord doesn't have a lot of friction on the frisbee and I'm doubtful that it will work well. Maybe with a better material for the belts...

Surprisingly, it worked with the lexan touching the ground and with the lexan about 1/4" off the ground! I have a feeling that when the flap was elevated, the frisbee would momentarily bend the flap into the ground as the arm ran into it, which allowed the frisbee to slide over the flap.

The hopper is included in the video; the track will hold 4 frisbees and act as the 'hopper'.
