Step 22: Final product

There she is, just before her first real test. For the most part it works well but there are some things that will need upgrading in the future. To see it run check out the video in the very first step. Thanks for reading!
Notes for 2.0<br>1. Sentry mode.<br> -A laser scan that shoots anything that moves<br>2. Tank tracks<br>3. 360&deg; wheels for tight turns<br>4.Thermal camera<br>5. Input for other guns like the demolisher so you can shoot misses and darts or a vortex blaster.<br>I really like the idea you had of solar back up.
<p>that would cost hundreds of dollors.</p><p>even only the thermal camara would cost about 500 dollers</p>
<p>sounds really cool. Have you ever thought of adding a water gun to it</p>
<p>you should attach a gopro on the turret of the gun and somehow buy glow in the dark nerf bullets so it looks like tracers at night time!</p>
<p>how do you do it</p>
This is awsome
Suggestions for mark2 of the sentry: cattipiller tracks for mobility, airsoft or paintball gun, hydrolic system to aim up and down, portable remote with screen for when your in the battlefeild so you may control it under a critical circumstance. I hope this could help, I would really like to know if it does(I'm not a good builder but I got ideas ;D)
Could you combine this with the Nerf Sentry Gun (http://www.instructables.com/id/Nerf-Vulcan-Sentry-Gun/) to create a deployable sentry turret you could drive to a location and set up?
Can you please post a parts list?
Does the nerf gun have a &quot;sloppy&quot; trigger (hard to pull back) or a &quot;hair&quot; trigger (easy to pull back)? I am trying to build an rc turret and use an airsoft gun with a relatively light trigger pull, but the servo I am using seems like it doesn't have as much power to pull back the trigger.
its a soft trigger ive used before and really easy depends what type of nerf gun ur useing? <br>
I can't check because I sold the gun. <br> <br>But I would say the Vulcan has more of a hair trigger when running on full auto battery mode. (since the trigger is just activating an electric switch) When you put the gun in manual mode its tougher because the trigger has to release a spring. <br> <br>I was just using a standard Hitec servo which was rated at about 50oz-in of torque. <br> <br>Try making the arm that pulls the trigger as short as possible, it will be able to transmit more force. For example, my servo can transmit 50oz-in, so if the arm was 2in long it would only transmit 25oz of force. (approx)
Ok thanks. I think I might need to find an electric gun because it can't pull back a spring that well.
How much would you charge for a complete system minus the computer and the sound system?
what nerf gun is that
A 'Vulcan'
where did u get that trigger mechisim and how much was it<br />
Its an RC&nbsp;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.<br />
what about home hardWARE
You can get 'em cheaper at hobbyking.com. Their cheapest one is about $2. <br>Great shipping prices too.
The servo that activates the laser is actually from Hobby King, I just happened to have lots of the Hitec ones kicking around.
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?
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.
could you actully hook the camera up to the tv cause it would make it alot cheaper for me
hi do you think it would be possible to combine both a pan and tilt system for the gun?
What is the range of your RC system? <br> <br>Now, the big question: How fast does it go?
Its 50 rpm . in the first few steps he wrote that<br>
i think he means how fast does it go forward....
airsoft machine gun anyone?
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?
I'd stick with brushed technology. Finding good reversible brushless controllers can be difficult and expensive.
not really..Hobbyking.com has some decent Brushless Speed controls... some are $100 or less<br><br>
Hobbyking.com has brushless speed controller (esc) for a model airplane or helicopter for $20 or less
True, but they aren't big enough for a project this size...need more amperage....otherwise you'll just fry the ESC
make it do a barrel roll
relay = 1.50<br>servo = 15.00
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 &lt;$5 these days.
what servo u use<br>
You should've wired it to the gun. The servo was a good idea too though.
can you use the vulcans tripod instead of the turret and mount it at 1 place?
how do you control the tank,what did you use as a controller
at least you hide the switch inside or something just don't let your enemy found it so easy.
Hell March FTW!
i want to build a 1/4 scale rc tank.. how do you wire the motors. and how does the steering work.
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.
i think its much like a tank, to turn right, the right motor turns off, and the left keeps going, and so on
Are you insinuating that your job is driving a self-propelled nerf gun around? <br>(if so I want that job)
Where'd you get that battery?
With that kind of power you could easily upgrade to a tank track. <br>To keep the speed the same you could use a drive sprocket the same diameter as the largest road wheel.
