[FTC]: Picking up balls

[h3x]

We are struggling to find an effective and easy way to pick up balls, preferably using parts we have.

We are planning on using a scoop type thing, but I don't think this will work well. I would rather it be a system where we just drive are robot into the balls and they are automatically lifted.

Any ideas? Thanks.

Look at FRC robot designs from the 2006 aim high season in which they had to pick up poof balls. I saw a lot of this particular design in the FTC Hot Shot season but I don't have ready access to pictures of those FTC robots. So look around for hot shot wiffle ball collectors for inspiration.

Find a copy of FIRST Robots: Aim High: Behind the Design. It showcased 30 designs in great detail from the Aim High game.

Amazon

Thanks, that's not a bad idea. I don't think I want to buy a book though, at least not yet.

Any others?

Think about how sports pick up mass amounts of balls. Just like in FRC, the people who play sports must have lots of practice to succeed, thus they use many balls at a time to make practice more efficient.

Find game footage from 1992 FRC on youtube. It exists, though that mechanism may be a bit more complicated than what a couple of sports use.

Interesting, so like a big wheel that lets balls get caught in it? Maybe, but that could be too big. If the balls need to get 16 inches off the ground, the wheel would take up almost all of the space for our robot. But, I suppose it could work well. I am going to look into this more.

Any other ideas? I can never have too many

My team looked at several designs and prototyped 4 of them. A few examples:

And here is what my team feels is the best way to collect balls:

Nice, great post. How do you plan on lifting the balls up? Maybe you could stack a few of those on top of each other, then put a sheet behind them.

Thanks, nice concept. What kind of issues did you run into? Do you think this will work for the smaller and heavier racquetballs?

We didn't have to many issues with this one, we actually made it bigger for the final one and it worked a lot better. We are doing something a bit different this season
