This is also my first instructable and also I've already created it, so I kind of have to show you what I have, and can't really show the steps very well
But hope its still okay
Also I made this while I was kind of tired so some things might not make too much sense.
Step 1: Materials
Motor (around 12 volts)
small saw blade
lots of wires
2 hacked servos (there are many instructables on hacking these on the net)
6 volt battery clip
12 volt battery clip
preferably a drill or mini dremel tool
pop rivets with some rivets
Step 2: Wheels and Servo
One this has been done (you can Google how to hack them) you need to screw on the servo horns on at the top. with them in place nicely.
The wheel can now be glued, preferably with super glue onto the servo horns, this keeps them in place. Pretty much any smallish wheel sizes can be used
Step 3: The Body
First a sheet of metal had to be cut out about the size of about
using the piece of aluminum sheeting.
You then need 4 small pieces of aluminum sheeting at about
for holding the servos into place
and lastly a backing part of two sheets of aluminum at
With these cut out, its time for placing the parts together
Step 4: The Body, Putting Parts Together
Anywhere near the middle should be fine (of the L piece).
on the top part of the L shape pieces of aluminum >L that part, must also have two holes drilled into them, they should be spread out apart enough so that the servo holes will be able to fit.
Holes must then be placed onto the bottom base sheet metal (10x21 cm) sheet metal, these holes need to be placed nicely and equally apart so that it holds the servo in place, and so that its near the back part of the base.
For mine I placed the two L shapes at 3.5cm and 8.5 cm from the back of the base, they were also about a Cm in from the side so that the servo could fit snugly while still over hanging the edge nicely.
Now just simply pop rivet the pieces into place and you have the start of the body.
Step 5: The Body, the Back Part.
Another two holes should then be placed on the actual base of the sheet metal too line up with the backing of the two U/C/[ shaped metal piece.
These pieces should be placed on the edge of either side of the base and nicely pop riveted into place.
For the last part, you need to connect a 10 x 4cm piece of aluminum cut out, and shape it so it fits around the motor, with some space at the end, kind of like the shape of a ? this allows the curve piece to connect onto the top part of the [ shaped aluminum piece while also allowing enough room for the motor (can be soon on the photo 3 and 4)
this in put in place with a drilled hole to the top part of the back of the [ shaped piece, and also another hole needs to be placed at the end of the sheet metal so that it can tightly grip onto the roof.
Step 6: The Body, Front Part
Step 7: Top Part of Body
for the back part, using the tin snips, a rectangle needs to be cut out so that the blade of the saw can fit nicely within, with A LOT of clearance, my rectangle used a 8x2 cm box (look at the second picture) placed at the exact middle of the top sheet.
the front bit then needs to be measured so that the holes can be places from the hinges, so that the hinges fit on each side, and it allows the top part to swing open an shut. Drill the 4 holes for the hinges and then hold this in place with rivets.
With the motor holder created earlier for the base part find where the hole lines up of the ending part so that a hole can be created on the top part, this is used so that a bolt can tighten up, and this tightens the motor onto the roof or the body.
with that hole placed correctly, you can now pop rivet the hinges onto the top base.
4 holes also need to be made for the top part so it connects nicely onto the [ shaped thing, bolts will later be placed here to connect these parts together
Step 8: Electronics
With that done its time to start adding the electronics for the car, to make it movable using the remote control, first part is to connect the servo onto the L shaped things used for the base, its probably best to use the screws that came with the servo, although you can also use bolts instead
This needs to be connected onto channel 1 and 2 of the receiver, with also the battery pack of the receiver.
Everything can then be sticky taped onto the base of the car
Step 9: Weapons
The weapons can be changed to however you like, I just connected the blade onto a 12 volt motor, This isn't the greatest weapon ever, but the speed is pretty quick and I probably still wouldn't touch it, you can connect it how you like, with the blade I bought, I glued two pieces of plastic over the huge hole on the blade, using super glue.
With that I placed a small hole in the middle of the plastic where the motor was connected right though. The motor was then placed onto the motor holder of the base part.
Step 10: Motor Wiring
The motor can be wired fairly easily, just by connecting the two wires onto a battery with a switch in between (note the picture is a 6 volt battery clip, but you can up it to 12 volts to make it much faster), this will mean once the switch is on then the motor will start spinning and so will the weapon, then the other switch can be turned on for the receiver and this will allow the wheel to be able to turn using the transmitter.
Step 11: The Ending
Lastly bolts need to be placed for the back part to keep the top on properly, and also for the motor part so the motor gets pushed against the top of the base, this then pretty much completes the battle bot :D you should now be able to drive it around and crash the back part into things,
As i said its not the greatest thing, but its still pretty cool, also if you would like me to elaborate more on any part, just tell me
