RC Nerf Tank

My first ever Instructable, yay!

This was one of the more fun projects I've attempted and I'm fairly pleased with the results.

Most of the parts and skills used in this project are from my fighting robot hobby. It might seem like a complex project but anyone with basic handy-person skills and willing to do the research could build a similar machine.

Anyways I'll let the rest of the Instructable do the talking, enjoy!

Step 1 The Design

I'm not much of a computer aided design guy, I tend to get a picture in my head and go with that. I made a list of things I wanted the machine to include. Some made it and some didn't. You can also clearly see how good of an artist I am.

make it do a barrel roll

[KarateLover21]

relay = 1.50
servo = 15.00

[travis7s]

Yes but how are you going to send the fire signal to the relay? The servo has circuitry to use the signal from the receiver. Also you get can servos for <$5 these days.

[jcharbonnet]

what servo u use

[etm34]

im thinking about doing this using 2 brushless motors, but im having trouble figuring out what i could use, anyone have any ideas. will they have enough power?

[travis7s]

I'd stick with brushed technology. Finding good reversible brushless controllers can be difficult and expensive.

[Furball_Fidelis]

not really..Hobbyking.com has some decent Brushless Speed controls... some are $100 or less

[sbracco]

You should've wired it to the gun. The servo was a good idea too though.

[sub893]

can you use the vulcans tripod instead of the turret and mount it at 1 place?

[pitla_james]

how do you control the tank,what did you use as a controller

[[corosive]]

why did you need the black box? was the camera wireless, or did you have to have it wired to something, and how was it powered?

[travis7s]

The camera itself is wireless, it runs off a 9v source. It transmits to the silver receiver box which is designed to plug into a TV to display the video. Most laptops don't have the RCA connectors that a TV has, so I needed the black box to convert the RCA input to USB.

[deqwer]

at least you hide the switch inside or something just don't let your enemy found it so easy.

[Chowmix12]

Hell March FTW!

[Jedx]

What is the range of your RC system?

Now, the big question: How fast does it go?

[adhimahajan]

Its 50 rpm . in the first few steps he wrote that

[playpep]

i want to build a 1/4 scale rc tank.. how do you wire the motors. and how does the steering work.

[adhimahajan]

you can buy the motors ,chassis , wheels , battery , wireless module(evrything) From robokitsworld.com . Choose the ps2 controller take the 54.68 dollar one and NOT the 39 one as it doesn't have the motor driver.

[zack247]

i think its much like a tank, to turn right, the right motor turns off, and the left keeps going, and so on

[m4a1sopmod]

where did u get that trigger mechisim and how much was it

[travis7s]

Its an RC servo. It is a Hitec HS-311. You can get them at local RC hobby stores or at online places like servocity.com for $9.

[Jedx]

You can get 'em cheaper at hobbyking.com. Their cheapest one is about $2.
Great shipping prices too.

[travis7s]

The servo that activates the laser is actually from Hobby King, I just happened to have lots of the Hitec ones kicking around.

[Jedx]

Are you insinuating that your job is driving a self-propelled nerf gun around?
(if so I want that job)

[Jedx]

Where'd you get that battery?

[Jedx]

With that kind of power you could easily upgrade to a tank track.
To keep the speed the same you could use a drive sprocket the same diameter as the largest road wheel.

[ilpug]

me and my friend made a really ghetto one of these with a cheap little airsoft gun and servos and controllers from two different rc cars. works great.

[shamik g force]

love it

[bmx__chris]

is there a way to make this servo as one wireless add on button?

[trd-outlaw]

Very nice tank for the turrent i suggest looking at how the horns on older cars are made so you can then spin the full 360 i made a picture below the red and blue dots on bottom place run on copper tracks on the top plate so you have wiring to the bottom and different wiring from top to gun so when you spin the gun the wiring stays stationary

[travis7s]

Thanks for the idea, not a bad concept. Might be a bit tricky to pull off the circular tracks without making a circuit board. That and the nerf tank has been deconstructed for quit e awhile now. (needed its parts! :P)

[hobbitboy]

what nerf gun is that

[travis7s]

A 'Vulcan'

[trd-outlaw]

here is photo

[patricrox]

how big is this servo? it looks like a micro

[travis7s]

It is a micro, I think it is a 9gram servo.

[planetsideplayer14billion]

where did u get the wirelsess cam and howmuch

[travis7s]

I got it from Chinavasion and it was about $25.

[0r7iz]

NICE JOB...how much did u spend on this little sucker?

[travis7s]

Well I didn't spend very much at the time because I already had most of the parts. I would say it would take $500-1000 to make something similar.
