boebot nerf assault vehicle (picture updated)
love the boebot!
thought maybe you'd be interested in seeing my mod of the boebot:
·
Yes those are nerf missiles in that turret.
cmucam tracking coming next.

good job on the kit parallax!

i wonder if parallax makes a part for that.
the project actually will take another turn when my cmucam and pan/tilt turrets show up.
the nerf turret is surprisingly lite, so the bots not hurting for motion yet.
its still a little front heavy and will tilt forward if i dont ramp down forward motion.· once the new pan/tilt shows up and i build a separate platform for that, i'll be able to distribute the weight a little more appropriately.· definitely a fun thing to experiment with.

As for heat-seeking missiles...
You need bigger missiles than those that comes with that kit.
Buy a couple of OEM SMT BS1/2 sets, make a small PCB for the crystal(for the ground plane), then glue it and the chips into the nerf-missile, but skip the voltage regulator and the undervoltage reset chip. Solder the thinnest wires you can find to the IC pins( Mounting them on a PCB will add a lot of weight). Carve out a slot for a 3V button-type cell and add copper wires to work as contacts.
Control?
Add solid fins at the rear and smaller moveable fins at the tip(like on a Sidewinder missile)
These may be activated by pieces of nitinol wire, or possibly the steering components from two of those cheap, little micro-RC cars (For both horisontal and vertical movement)
Find a single IC(in SMT size which can drive the currents needed to activate the nitinol for short periods) and connect between the BS and nitinol strings.
Infrared guidance?
You'll need a couple of IR sensitive photo-resistors or something.
Stick one in the center of the tip and four around that again, and separate them with tin-foil.
Connect it all to the BS....
The reason the voltage regulator and the reset chip is excluded is that using 2 x 3V batteries will add too much weight, so we run the BS at 3V instead. (It will actually draw less current in 3V mode, and both PIC and EEPROM tolerates such low voltages)
Because there's no reset, it may act weirdly when the voltage drops too much, but as it's not a 'serious' project...
Programming the BS, though will be a bit difficult...
(Maybe use a stock BS and unsolder the EEPROM from it when you're satisfied or make a mock-up BS with a SMT socket)
Me and my imagination...
I actually forgot about the parallax tank treads.· that might be an interesting idea.
I had thought about recycling the tread system from the original toy, but i think i'm going to save those for my next platform project.
the boebot treads would look pretty sweet.
I'm still laughing about the detailed build description of the guided missile system from above.
i think somebody has really thought this through waaayyyy before i built my bot.··
i think i'll check my robot budget (or as my wife calls it 'your allowance') and see if i can squeeze some treads out of it.
·
I thought it up as I wrote themessage...
(I've been experimenting with running a BS1 on 3V, though, and somewhere I have a Nitinol book and some thread)
Anyway...
As you may have noticed, I didn't give any examples of guidance programs.
That is because I don't want anyone shooting down an F-16 with a homebuilt guided missile....
Also, note that while IR sensitive sensors may be expensive, using ordinary light-sensitive should be good enough for a night-fight if the target is foolish enough to have a bright light(like an afterburner)...
Before anyone starts messing about: note that while amateur rockets can be fun, in most countries(Including the USA), fitting ANY active guidance to it will make it into a missile and very illegal without a permit.(which they won't give you.)
How they would react to someone fitting guidance systems to an othervise inert projectile, though, is anyone's guess...
hmmmm...
maybe i've found a new project.· I did get some new pan/tilt turrets in...they'd be a perfect platform.
some food for thought.

i dont think you'd get too far down the sidewalk on 4 AA batteries powering pan/tilts, sensors and the additional weight of the rockets. but yeah..it would look cool.
I'm ordering my tank treads now...this should be a fun add on.
Where the H*ck did you get that nerf-tank?
(I can't find it online... )
I have seen them on ebay listed under: Motorworks Missile Launcher.
heres a UK site that has more information, but I dont think you'd want to import the toy:
http://www.firebox.com/index.html?dir=firebox&action=product&pid=512&showAllImages=0
but i have found a few on ebay for around 10-15 starting bids.
if you have a walmart nearby, then check them first.
good luck!

And I quit eBay several years ago because of all the scams going on.
Thanks for the link, though.
Seems like they have other fun toys, too....
how can that be?· thats impossible.
thats like saying theres no sun in the sky.
no walmart down the road is an urban legend we tell our kids to teach them appreciation for the walmart.
hehehehe.
you're probably better off without it.

As for the sunlight...
Too much of it in the summer and too little in the winter...
(I live south of the polar circle, so I DO get some sun in the winter, but I'm also so close to it, that the night isn't very dark in the summer...)
Causes havoc with my sleeping habits...
