Mine RN-1´s Electromagnetic Gun

Hi, after 2 weeks of mechanical, electrical and programing work I can show to you my new coilgun. Since I see the Coilosapien´s video I had to made my own... The gun is made in methacrylate and metal, and the RN-1 can reload it easily. To make the bag I use an old AC transformer´s case to keep the flash camera circuit, batteries for laser and charge and one mini servo to switch the laser and the shoot.


Some photographs:

And the first, but not the last video:

Now I have to work at the movements with the gun, at this time the RN-1 falls sometimes when is walking...

aguiloco,

Dude, that is way cool. :D I sure do hope you'll be sharing the gun information with us.

holly crap!!!! that is the coolest attachment for a bot ever.
i want one too......... please post the parts list and schematic when you can.


thanks in advance

Thanks for your opinions!

The electrical schematics are really simple, you only need a flash circuit from a single use camera (really cheap), condensers (I use two, 400V and 600 microfarades total), one switch to activate the shoot and one more for the laser if you wanna use it. The hardest part to make is the reload system, I try 3 before the last working system, you can make it using a micro servo to autoreload or use the RN-1 to do it. If you don´t have grippers can use any type of sujection to attatch the gun to the RN´s arm. The most important part is the coil, for mine coil I used 0.5mm copper wire around a pen. I choose 5mm steel balls bearings for the ammo.

This links will help you with the electronic better than mine poor english

If you can get that thing to fire paintballs, then you've created a new category for robot fighting. I wonder why fighting focuses on hand-to-hand combat, and weapons haven't been used much.

It would be a unique challenge to program your bot to fight with a staff, or ranged weapons. To make things even more fun, organizing squad combat would be ideal. 6 bots to a side, 5 armed with paintball guns, 1 bot acting as a medic. Much more challenging than Halo.

Good thing about a paintball hit is you would know when you were hit. Bad thing would be the cleanup. :o

Isn´t posible to shoot paintballs because it can throw only magnetic metals, no plastics. I´m thinking about to make another one using gas, this kind could shoot any kind of balls, and as you say would be great to see combats between robots using guns!

great mod!

could you let us know how robonova interfaces with the coilgun - i guess you fire it via the remote, but it would be good to know how this is achieved.

thanks.

(looks like i've got something else to mess around with this weekend!)

The interface is very simple, the RN-1 grip the gun, reload it and aim using this programing:

http://robosavvy.com/forum/viewtopic.php?t=1808

I use one servo that activates/disactivate two switches for laser and shoot, but you can use two nails that make contact for the shoot switch, because is hard to find a small one that can handle this shortcircuit (I broke more than 5...)

I will make anothe bag for the circuit, bateries and servo because this one is a little heavy for the RN-1.

I am building my own coilgun out of free pre-developed disposable cameras from instructions on instructables.com. Just a quick question, how many capacitors did you use, and how many wraps for the coil? Also, is the magnetic pulse created by the coil damaging to the robot?

Great job!

Wooh, first post!

Hi bbrainmonkey! For the coil I did 8 or 9 wraps, the best is to make some kind of coils and test it, I did a lot before this one. Now I´m using two 400V 330microfarades capacitors in pararell.

How you will make the reloading system? Post some photos!

If you don't mind, what weapon do you usually used in a hand combat?

There's a 'MechWarfare' league at RoboGames that does exactly that. The HQ is in the Trossen Robotics forum here:

:( such a shame people use some substandard image web hosting to link their pictures and 2 years later the pics are gone or have some nasty adverts on them (this includes photobucket)
