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

wow cool they are only $7.35

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!

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.

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

Too complicated and unreasonable!

I'd recommend you use The Force instead!

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?

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

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

[dtengineering]

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

guys this is not in the updates I have looked It is not there! If so please prove me wrong

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

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*.

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?!

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.
