how to make a very simple robot

this is my 1st instructable,so please tell me if it is good.

so im going to show how to make a very simple robot:the beetle robot!

it uses no chip,no programation,only the simple 3th connection

Step 1 Get all the materials needed!

ok so get all these.i got them mostly from broken toys,i'm sure you can find them at radioshack.

- a AA battery holder -> holding the batteries
- some solder wire -> soldering
- some wires -> connecting motor to switch,to batteries
- 2 AA batteries -> powering the motor
- 2 1.5V motors (preferably identical) -> making the robot move
- a slide switch -> ON,OFF
- 2 SPDT (Single Pole Double Throw) switches -> used for antenna
- 1-2 paperclips -> glue on the antennae so it is longer
- some glue sticks -> use with the hot glue gun

how much rupees you spent for buying these things for the very simple robot.

[Battle Bot]

Can you post a video how to make it so it easier to understand please?

[sai kumar]

can anyone please tell me where to get those spst switches
in india

[sudip chatterjee]

hello sir i am persuing b.tech (1 year)(ec)
your robot is marvouleus , but can give me a hint of making a very very simple robot or a circuit design of four wheel dc toy moving in any direction as the direction given by us with the switch.
i am trying to to make your beetle robot.
please give the idea soon.

aint gud

[rishabkhincha]

nice robot
but please mail me an easier to make robot as im just a beginner
my email address is [e-mail]
thanx

[rishabkhincha]

can we use other normal wheels compatible to this motor

[rishabkhincha]

where do we connect the SPDT switches

[Fujin95]

What toys can you get the SPDT switches from?

hey man

You took the image of step 15 directly from my Make article!

You can credit people work and give the link to my instructables when you copy something.

Is that why there is a diode in the circuit diagram, but no mention of it in the article?

[robomaniac]

There is no diode in diagram of step 15, those are green arrows to show the direction of the voltage/current in the circuit. I totally agree that can be confusion for beginner.

sht...sorry,i saw the image on google and copied/pasted it

[sparkspooky]

iM IN THE MIDDLE OF MAKING ONE BUT I WAS WONDERING IF HOT GLUE WOULD STICK

[sparkspooky]

robomaniac created the same thing so did I were you inspired by his instructable...............................ZACHARY SEVILLA OUT PEACE!!! -----------+---

[Win Guy]

This is SOOOOO cool! It's just like little robots called "Hexbugs". Now, instead of buying them, I can BUILD them! :D Thanks a LOT, coolrobot! Win Guy

[elenwaren]

youre beetle robot is new generation

[haranu]

hiiiiiii u have made aa nice robot i hav jst watched it and i will try to do this if it get succeded i would be very greatful to you

[mynameishamm]

NC=Normally closed,NO=Normally Open?
Sorry i'm braziliam noob

[derbert]

you got this from robomaniac's instructables- beetle robot and beetle robot v2 revisited.

[coolrobot]

why?because i made a beetle bot? i went in USA so my dad's friend who is a HUGE fan of robots and makes some and he told me how to make a simple robot i dont want to take credit for anything but i just wanted to show some people who like robots (like me) how to start their hobby or whatever

[paintsniper]

mine is so good ive been doin robotics since i cant remember if i get time i will post a instructable

[coolrobot]

i'm really interested in robotics and i have been gathering parts for the past few months and now i have started building some things

remember to rate my inscructible! =D

[AndyGadget]

You really need to add a circuit diagram to this or make the wiring picture MUCH clearer. The critical thing about this type of robot is the wiring of the switches to give it its 'behaviour'. A video would be good too. Wheels from some of the small Lego kits work with that type of motor if you drill out the holes very slightly.

thank you for the ideas! i was going to do what you said before,but my dad got home and he went on the computer.i saved what i had and published it. i'm going to edit it soon by the way,i can't make a vid because i was going to but my grandma (who is in visit...) called my 3 year old brother and he ran so fast that he didn't realize he had destroyed both my robots.now i have to make another one but i have to order some parts and my parents dont want to thanks again - Alex
