I actually did this last summer and manage to lose the footage.  Not vary good footage at the end because some idiot (i wonder who that could be:P) used night to film fire...... oh well

enjoy!

Do you have a diagram of the way you made the flamethrower part move up and down. It look like a good method and im involved in a similiar project.

there is not much of a diagram because i have the pan and tilt servos running directly from the rc receiver which is controlled using the the left joystick.  this is probably the simplest way to do it.

The pilot light is butane and the flame fuel is just \$.99 carburetor cleaner from walmart which seems to be the best

whoa that thing is awesome but what in the world could you want to use it for. I mean it has to be dangerous (I want one)

nice Job, that is bad ass!! Is that an rc truck chassis you used or did you make that as well? Have you thought about using an electric igniter instead of the butane torch, such as one from a gas grill? It would probably take up less space on the turret. I am not trying to criticize just throwing an idea out there

i initially used a el-cheapo hand held butane BBQ lighter from walmart which had a piezoelectric igniter. it worked ok, but i had to have a big servo to push the trigger and it was unreliable.  I wanted to build a transformer to supply 500v but it turned out the be way to heavy.  Dont get me wrong, there is a ton of improvements that can be made

i think newer grill ignitors are battery powered (at least the one on my 2 yr old grill is) it would probably be easier to use than a piezoelectric one

early prototypes involved something of that nature but the one in the video actually has the carburetor cleaner can on the robot.  I works great because when one is empty you just replace it with another of the self

As far as dispensing the fluid.  early prototypes involved a small solenoid valve but this added a lot of weight and i couldnt control the flow very well.  Final design uses a 4" long aluminum rectangle bar as a lever with a standard size servo.  Now i have flow control and it is very light weight. see pic

I made this a while ago and the project was poorly documented and robot has been parted out and turned into other things muhhahahaha!  However, i have a ton of pics and make a slide show vid in a sec if you want as well as answer questions.  off the top of my head for the thrower i used:
-bernzomatic pen torch
-el cheapo portable barbecue lighter
-heat sink i found in a old car stereo
-a feed roller from a printer
-some perforated steel grill from an old stereo housing
-tip from a Lincoln wire welder
-scrap pieces of aluminum and a couple 4-40 screws

I've been working on a slightly larger robot (hint hint, as you will all see) and will be making a bit of a larger flame thrower so stay tuned!
