Picking frisbee off the floor prototype

[falconmaster]

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.

Nice work.

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...

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?

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?

We could not get a high enough coefficient of friction, that does mean it can't be done with a different belt though

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.

How close to the ground are you?

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

Looks great!
