Our prototype robot in its almost finished state. Not all the materials are finalized, and the bumpers are just there as stand-ins. More to come as the week progresses.

Nicely done. Looks good.

How many balls can your Archemedes screw hold?
Do you have any way of keeping the target stationary? or following a target?

Re: 1153 preview

The Screw holds about 23 to 24 balls. The Camera isn't in the picture but it follows trailers and will hopefully help control the shooting speed. Though its not so much as a shooter as it is a tosser.

Re: 1153 preview

Nice! Can you shoot/dump right up against the goal at the same speed?

Re: 1153 preview

Yes it can. What we do is we slow down the shooter wheel's speed so that it can dump them out for close targets or we go full speed to shoot at targets farther away. It's range is from next to a trailer to 5 ft away without losing much accuracy.

Re: 1153 preview

During the competition, we realized that we couldn't accurately shoot at a distance of 5 ft. while moving. We made a quick modification to the shooter opening that allows us to still shoot with the same speed, only the balls go straight down into the trailer now. It helped us a lot and was a great improvement.

Re: 1153 preview

Certainly a force to be reckoned with at Boston, one of the best driving, most dangerous teams out there. Best of luck in Philly!

On a side note, what kind of gearing did you have on your drivetrain? That thing was really quick!

I wasn't involved with the drive train, so that might not make any sense... Haha. Congrats on your win at Boston, by the way!

Re: 1153 preview

You guys were absolutely disgusting (in a good way) at Boston. It was fun to share a hotel with you. Funny that we'll be seeing you again at Philly. Who knows, we might be in the same hotel again. We'll be at the Holiday Inn Philadelphia- Cherry Hill. Best of luck with any of your upgrades until then. Although the thought of upgrading that robot frightens me.

P.S. "Hometown Pizza." "Do you like to be tickled?' (Someone on your team will get that)

Haha, I'll look into what hotel we're staying in and get back to you.
We've got a few upgrades planned, some changes to our autonomous patterns, a faster ball intake, and maybe tapping into our currently unused 3rd gear. We really want to impress at our first foray into Philly.
