Re: How can we drive on this new floor?

So Zyck_titan it seems you had the same idea I did... >.< and I thought I was original.

We did the math and with a 480 watt (the maximum wattage motor allowable) you could produce just under .2 psi. (allow variance for rotor blade type) Numbers for this were taken from a website publishing the Static Pressure capabilities of their 480 watt fans. (we then did conversions to psi)

Now you have to multiply by the square inches (maximum allowable 1064 = 28x38) and we get about 213 pounds of extra force.

So if you had a skirt around the entirety of your robot you could conservativly expect to roughly double the weight/normal force of your robot. (you'd lose a lot due to inefficiencies)

This means that when applied to F=MA in regards to your acceleration you can expect to take it from roughly .6 m/s (static friction with no fans) to 1.2-1.5 m/s (static friction with fans)

Now logistics might be a tad tough but hey if it gives you double your friction then it's worth it in my book. The real problem... ripping up the play area. If it isn't secured you would just vacuum it up and be completely stuck. This seems a real problem to me since when you look here ( http://thebluealliance.tumblr.com/po...field-elements ) at the end you can see the edge of the field which is merely secured with TAPE and now if this is a thin linoleum style roll you would just suck it right up and then... you wouldn't be able to move and might even get a penalty for destroying the field.

...after further research ( http://www.frpshop.com/pdf/installat...structions.pdf ) assuming FIRST followed these rules for the construction of a gasolenar frp floor it might not be too much of a problem...
