i'd just be concerned at what the safety judges will say...

what rpm are you running?

what do you have to stop hands, fingers .oose nuts and bolts, broken bands from orbit balls etc... from getting in

hope it works...

we're just a rookie team with a standard kitbot... sadpanda...

although, we did notice that our narow orientation was alot better at pushing than some of the wide robots (they'll have issues with non-bumper contact...)

I think they have safety mesh on now. Looks like they have the minimums "suggested" by FIRST, so they should be good.

I don't have a video, but i did see them pushing us sideways on carpet while gaining speed multiple times at our scrimmage. No amount of traction control is good against that fan.
Tell all of your alliance partners good luck. They'll need it just as much as your opponents will. :rolleyes:

Sweet. A little bird had already hinted to me about the prop.

Where's the camera? Certainly Eric has some autonomous plan up his sleeve.

Hows the weight?

Looks VERY competitive.

i believe now were only like 1lb over weight and yeah eric and mike got some nice stuff up their sleves for auton i hope and we did put mesh on it and we had every meember of the team try to stick there fingers in it and no one could get passed their 2cnd knuckle:yikes:

what is with all of these teams using fans, i find them to be too unreliable and lack the stearing cabilites, but sure go ahead and use them

looks good now we must wait to see it in action but to me it'll just be a webcast

If you notice, they are not using the fan as there primary mode of transportation. They are really using it more like a turbo or NOS system just to give them a boost when they need it. From our preliminary testing we have found that fans can come close to doubling our maximum pushing force and acceleration. This means no matter how great someone's traction control is, someone with a well designed prop system will be able to out-push and outrun any bots that don't have it. If you can push anyone and catch anyone suddenly your scoring opportunities just increased dramatically.

The only downfall that I have seen is the extra power consumption.

Lemme tell ya. This thing is not pinnable, catchable or pushable. It scores really well, and the driver is very good, already. If I wanted anyone to design a fan it would be James, and if I could have it done any way I wanted for any cost, it would be like this one, with a sterolithography cowling. If I could have powered it any way I wanted, it would be how they did it, 3 cims. If I could protect it in the best way possible it would be like this. So what I'm saying is this thing is optimized and I am really impressed. If you think the fan will hinder your alliance, I can say right now they'd be my top pick, just for the bully factor alone (not to mention all the others). I also am convinced that this thing will be in the finals in Florida. Usually SPAM has work to do in their pit on Thursday, but from what I can tell this thing is done. They also have a practice bot. So Kudos SPAM, I haven't been this impressed since 2002 ;)

Thanks for all of the positive support. Especially, you, Dan.

We've still got some work to do. You are never really done until you pack up to go home from Atlanta.

While this is probably one of the best looking robots SPAM has built, there are a bunch of robots out there that will be better at scoring rocks.

But it sure is sweet watching this thing glide around the field. ;)

so ........videos?? i am really excited to see this thing moving.

Well..........looks like S.P.A.M. has outdone itself again, and built a fantastic machine. I can hardly wait to see how well it does. Great job!
Good luck this season. I wish we were going to be in Florida to see and compete with you.

Before you critisize the use of fans you should look into their usefullness.

The fans that we will be using (in 1729) are two 16" 8 pitch props that will give us 4.8 LBs of thrust each ... thats a total of 9.6LBs of additional thrust. I believe S.P.A.M.s propeller gives them a bitmore than 10 LBs of additional thrust.

If you consider that your robot will typically have between 9 and 15 LBs of thrust from the wheels (depending on whos' numbers you believe) this is a significant increase and can be a great advantage if the drivers can utilize that extra thrust.

Let me know what you think of the propellers after the regionals. Personally, I believe that there will be a propeller assisted robot on Einstien this year.
