Team update #4: alliances will receive 100 points for stacking robots red-blue-red-blue on the coopertition bridge.

Re: pic: Magnetic arm concept.
 

Step #1 turn on magnet
Step #2 Connect Magnet to bridge
Step #3 Magnet to random robot passerby and put him on your head
Step #4 Magnet Kitteh bot on top of Steampipe bot
Step #5 ?????
Step #6 PROFIT

No, The magnetic approach will not work for many reasons. However, what your looking for is a tractor beam like on star trek. Good old Mcmaster carr has one in stock that should fit in the FRC application and budget. It is part number 2643K1. Look into it.

Re: pic: Magnetic arm concept.
 

Interesting idea. Il bring this up at tonights meating so we can mull it over. Thanks!

Re: pic: Magnetic arm concept.
 

That's clearly a Dalek end effector, not a tractor beam. These are tractor beams. (Some are auto-resetting, heavy duty ones!)

Re: pic: Magnetic arm concept.
 

wow cool they are only $7.35 :D

looking at the picture and description I cant see how it works though...
Do you think this device will not break any rules?

Another Idea I came up with is for a weightless way for making the extra energy you need to power those throwers. (yeah yeah yeah only the battery can store energy but It said nothing about energy production)

you may have heard of it before its the Buttered cat paradox

This idea is very light weight and effective.
It is based on the follow two theories:
Cats always land on their feet/Buttered toast always lands buttered side down.

we just need to tie some toast onto the back of a cat and stick on the robot while harvesting the rotational energy. here is some illistrations


and remember guys use real butter not margarine!

Re: pic: Magnetic arm concept.
 

Can you imagine the amount of power needed to do that if it was an electro magnet!?!?! Its a good idea if it was a bit more realistic.

Re: pic: Magnetic arm concept.
 

read the whole thread I came up to a solution for the energy problem did you not see it !?

Re: pic: Magnetic arm concept.
 

Too complicated and unreasonable!

I'd recommend you use The Force instead!

Re: pic: Magnetic arm concept.
 

How do you suppose to get the robots to balance on top of you once you get them up there?

And wouldn't 298 lbs of robot crush you measly 149 lbs?

Re: pic: Magnetic arm concept.
 

Mill the chassis out of a solid block of Aluminum, to retain maximum strength.

Re: pic: Magnetic arm concept.
 

****** magnets. How do they work?

Re: pic: Magnetic arm concept.
 

This is a great idea, although I'd suggest using an extremely rare earth aluminum magnet.

I don't want the force if i can't use force lightning, violates r36:mad:

Re: pic: Magnetic arm concept.
 

Is this a legit team update? O.o

Re: pic: Magnetic arm concept.
 

No.

Edit:
All the official team updates can be seen here: http://frc-manual.usfirst.org/TeamUpdates/0

Re: pic: Magnetic arm concept.
 

100 points would be a brutal bonus if that was a real thing, though.

Our arm mechanism will change the way this game is played!

Re: pic: Magnetic arm concept.
 

NOOOOOOOOO!!!!!!!!!!!

I prototyped this today with two old robots and an electro magnet. Unfortinatly we all forgot something very important... Robots are made out of aluminium And aluminium is not magnetic so it doesn't work :(.

Unless you gt everyone to make steel robots, nah no one is that dumb *cough* 3662*cough*.

Re: pic: Magnetic arm concept.
 

Luckily for you, if you aim just right, you can hit your electronics board, and it's sure to work with that! I mean, come on, whose c-RIO doesn't like a good old electro-magnet to the motherboard?! :p

Re: pic: Magnetic arm concept.
 

That is ridiculous we would be violating r08, G26 and G27... Iwas trying to find realistic applications for this device withOUT breaking rules...


Even if it doesnt do damage I will be impressed if anyone is able to mount there crio in a way that it can suPport the whole robot.

Re: pic: Magnetic arm concept.
 

Sorry to burst your bubble, the bridge is made out of aluminum, which is not magnetic and most robots are made out of aluminum and it will not be able to be pulled toward magnets.
