This post was very interesting to me, since this is one of the many things I want to do in life. ...graduate from Purdue, become an electrical/mechanical engineer, build robots, start a company...

you go to purdue? cool, i have two friends that will be going there. unfortunately, one of them hates battlebots

No, no. I'm 13,

/curveball

but that's the plan.



Go Boilers.

[slade]

ahh, cool. are you on a robotics team?

[kosmo]

Are you allowed to make a flying robot?

not on purpose. but quite a few have taken flight.

(my team is sort of tempted to throw an airplane propeller on top of my bot just to see what happens)

[kosmo]

That wouldnt be the greatest idea. I doubt it would provide anywhere near enough lift, but it definitely would lose all semblance of stability once the wheels got off the ground.

[Sudz]

But it would get high points in the "well that was cool!" Respect!!

Vacuum doesn't work like that.

If you evacuate every molecule of air inside a space, then you have an absolute vacuum.

With no air pressure on the inside to push up, you have full atmospheric pressure pushing down (14.7 psi at sea level).

This is as strong as vacuum ever gets. Once you have removed all the atmosphere from a space, you can't draw any more vacuum, there's nothing left to pump out.

To moemag's ideas....

Can you really make weight limit with those ideas? You'd be really stretching it for the tensile strength to lift/impact with those arms at even 200 pounds I'd say. You have to break metal sheets that have some pretty good impact resistance and on top of that probably some reinforcements to prevent brittleness. I know at my university they are making fiber reinforced aluminum to provide structural integrity as well as impact resistance...

Your arms/weapons need to pierce or cause blunt force trauma so that means they need to be thicker, denser, and stronger than the strongest bot at the event to withstand the stress of taking on multiple bots. Also you'll need powerful enough motors to spin the weight of the arm along with the added weight of the competing robot. Unless you have some miracle motor to do this, you won't make weight class just on powertrain alone I'd assume.

Yes, I've tossed around quite a few bot ideas around with friends. It sounds fun but there is no funding for a program like that right now.

yeah well there is a little brain fart for ya.
well even at a 50% vac it would still only require 17 cu inches of area to add up to just over 120 lbs.

but you know what... take a chill guys. I was just reading and got a little interested in it and wanted to see what I could come up with having fun.

I dont care anymore. You sucked the fun out of it. didnt notice the LOL! and HAHA! that I was making toward my own idea huh. wow.

Sorry.

Happens to the best of us.

About eight months ago I spent an entire day trying to figure out a way to pour a pier for a parking lot light pole monolithically (IE foundation and pier all in one piece). . . . . . then I realized that the construction joint I was trying so hard to eliminate didn't make any difference anyway. Since concrete has basically no tensile strength, if that joint isn't there, it'll just crack through in the same place when a bending load is applied, so there is no reason to fight to omit the joint ('cause it'll make one there anyway).

Several hours wasted because I neglected to take into account a key property of the material. You can be sure I haven't forgotten it since though.

I like how I have to come on AO to get any info on the actual robots at this competition.
:dodgybutthereisn'toneonAO:

And you got an internship at Raytheon? Awesome...

yeah, you slacker, you didn't come to the competition.

[Cegasaturn]

If by slacker you mean not being able to conjur up the $775 that was needed to go, then yes, I am a slacker.
