Not to knock 358 for their brilliant strategy, it took some big balls to pull off (just one really ) but I feel it should be noted for all scouts who may see the picture that 177 continued to herd balls and narrowly win the match

Oooohhhhh...

Big arm.

How'd they do during the rest of the competition?

[EvanG]

How'd who do? Us or them?

We went on to win the regional, they however continued to play an excellent game into the elimination rounds where I believe they made it to the semi-finals. However, I could be wrong on that.

Congrats.

[EvanG]

Thank you. It was an amazing day, let me tell you that.

Hey Evan, you obviously had a reliable ball delivery system for your net. Can you give me some detail on the working of it?

Im not evan, but can answer the question just as well... at the front of the robot we have a knurrled roller thats about 12 inches off the ground, it runs the full width of the robot (about 2.5 balls worth)... The roller is run by a globe motor that has had one set of planetary gears taken out to give us the speed and power that we wanted. The motor is actually anchored inside of the roller so it gives us a direct drive with no loss of power, but at the same time doesnt take up much additional space. In the hopper itself there is a conveyor made of polycord which is run by a geared vandoor motor to keep the balls from jamming... This system results in excellent performance picking up and delivering the balls

Thank you very much for your response. Know I've just got to figure a way to apply a similar system to our robot...

I don't mean to be the Devil's advocate here, but don't expect to get it right your first time. I will say that 177 has tried several times to do small balls, and it took forever to finally get a system that works. A lot of it is just trying and trying till you get it to work. I'm sure you'll get it eventually.

Also, it's minor, but the polycord conveyer on our bot is actually powered by a van door motor while the basket is currently opened by a geared window motor. This may change and we may be opening the basket with vacuum because its much more forgiving.

Oh i understand entirely. We have a ball hopper too, and our only proble has always been the delivery of the balls. We played with it all through our regional comp, with limited sucess. Hopefully that will change for nationals. Thanks for your help.

P.S. I dont want to be intrusive, but do you have pics of the system you have?

Our team also had a hopper. The hopper itself worked great and we caught 16 or 17 balls every time, but our delivery of them didn't account for the small lip inside the ball corral, and we lost many of the balls.

Oh, well. Glad yours worked for you.

We went to four matches in the quarter finals but were knocked out.

A team at SBPLI Regional approached us to do it to a team there, but something happened and we didn't have a chance to do it. We decided to use it agains 177 however.

Also I'd like to add that 177 really recovered and pushed the loose balls to their human player.

Also, I noticed after that match 177 really made sure this didn't happen again - the drivers would keep the nets closed until a second or two before the balls dropped. Good job guys.

We decided to drop it because we weren't sure if some of the balls would hit us, then we would be blocking them from falling in - which is against the rules I believe (I'm not positive about that however).

I love seeing pics like these lol! I definitely want to try to see if we can do that in atlanta... it just looks so funny to me to see one robot capping another!!
