Step 1: Tools and Parts

The tools needed to create BatteryBot
Soldering Iron
[Needle nose pliers]
Wire strippers/ Wire Cutters
Lighter or heat gun

The parts needed to create BatteryBot
[2] 1.7volt LED
[1] 9v battery lead
[1] 9v battery
[1] 330 ohm resistor
Heat shrink tubing
[1] (8mm) x 11/16 in length
[2] (4mm) x 3/4 in length
[2] (3mm) x 15/16 in length
Electrical tape
Wiring Loom (3/8) x 1 in length

Step 2: Lay Out Components

Step 3: Find the Negative (cathode) Side of the LEDs

Mark the cathode of both LED's with a black sharpie. Mark it closer to the plastic lens in order to see it better later on.

Cathode: This is the short lead

Step 4: Shape 330 Ohm Resistor Into Suitable Head

Bend the resistor to fit the width of the large diameter (8mm)----11/16 in length of heat shrink tubing.

Step 5: Solder LED to Resistor

Hook the ends of the resistor and LED
Solder joint so the LED and resistor are straight in line

Bend the wire on the LED side for a tall head
Bend the wire on the resistor side for a short head

Step 6: Solder Second LED to Resistor

Repeat previous step for the other side
Optional: (trim excess of lead in order to keep the arms the same length)
Be sure that one side of the resistor has a negative LED lead soldered to it and the other side has a positive

Step 7: Prepare the Ends of the Led Leads

Measure the width of the head unit

Clip leads so they are in line with the width of the head

Make sure the leads are approximately the same length

Step 8: Prepare the Power Supply Unit Interface

Slide the small diameter (3mm)---1 in length of heat shrink tubing onto the leads

Step 9: DON'T FORGET !!

NO really, don't forget to slide the small diameter (3mm) ---1 in length of heat shrink tubing onto the leads

Step 10: Solder Battery Connector Leads to Components

be sure to have the black wire(-) connected to the negative (cathode) side of the one LED

This side was the one the WAS slightly shorter
It will be the side with the flattened spot on the plastic part of the LED

Solder the leads so they are straight in line with one another

Step 11: Solder the Positive Lead to Components

Be sure to double check that the connections have been properly made

Note: This might be a good time to check that the system works by attaching a power a source
(AKA: a battery).
Hint Hint

Step 12: Apply Heat Shrink to the Robotic Arms

Position tubing to cover joints. A gap may be left near LED end for aesthetics
Use a lighter to shrink tubing
Make sure to keep the flame slightly away from work and move it in sideways towards tubing
Use the side of the flame rather than the tip to prevent blackening
Do it in small portions

Optional: Use a heat gun if available

Step 13: Create Head Unit

Tape the head by wrapping around one lead first and then around the whole head.
Press down on center.
Slide the 8mm heat shrink tubing unto the head and straighten any bent leads
GENTLY apply the heat shrink by heating with heat gun or lighter.
Do not shrink this one too much

Optional: Use arm mounted high energy disruptor beams if available

Step 14: Finishing the Arm Units

Using the (4mm) X 1/2 in heat shrink tubing create the arms
Slide tubes on close to body
Heat shrink

Step 15: Create the Main Body

Wrap the power wires so they are approximately the same length as the (1) x 3/8 in piece of wire loom
Tape wires
Attach loom

No tape needed on loom

Step 16: Final Assembly

Install face by means of a black sharpie
Attach 9 volt power source

Optional: Use wire markers to create a face that you can reconfigure

    find them in old things like well any old tv the on and off sswitch should have one

     never take apart anything with ray tubes(ie: tv's or monitors)  They hold charges for a very, very, very long time; so it is easy to get the shock of your life if you mess with one. Leave that to professional TV repairmen.


    Reply 9 years ago on Introduction

    no unless your messing with the ray tube there shouldnt be a problem if youre worried use insulated screwdrivers and wear gloves

    lol i steal mine from my dt department in my free periods :) they have draws and draws full of them

    I cant understand why you have VERY crappy pics and your instructable is rated 5 and my instuctable is very good pics and explanation and it is rated 0! aaaaa i am very unlucky man i am going to cry

    Cool! Now you just need a little piece of muscle wire to make them wiggle! You can get a meter of wire for under $20 - that should be enough for at least a dozen of these little guys.


    12 years ago on Introduction

    very nice idea! i will definitley make some of these tomorrow


    12 years ago on Introduction

    Sorry if this was answered or a lame question but do you have an approximate lifespan on one of these robots (err, the batter rather)

    Woot! Battery man! Lol make like 20 of them and put them on a usb cord for an awesome decoration! :-D nice one!

    Wow thats is seriously cool. Keep up the good work. I might suggest it to the new instructazine collaboration if you don't mind. Although it might be quite long till the instructazine gets completed, as most of us is at work or school :/ . So do you mind if there is a possibility that your work gets used in the instructazine magazine?

    That would be Cool! :)

    Aww, that's adorable. I'd like a swarm of these dudes.

    Excellent instructable, laid out well enough that even a klutz like me could follow it. I wish others went through as much effort to create as complete an article as you did.

    cool these would be fun to make itd be cool to have a army of em and dress em up in mini camo with mini guns
