Introduction: 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

Step 2: Get All the Tools Needed!

i borrowed all the tools from my father,once again,they should be available at radioshack

- wire cutter and stripper ->cut wires and strip them
- pliers ->shape the antennas
- hot glue gun -> glue the switch and the SPDT switches on the battery holder
- a soldering iron -> solder and connect wires together
- a multimeter -> check the battery

Step 3: So,let's Get Started!

check the battery's power - =D

if its' on <<good>> use it

if it's on <<bad>> change it (in my case,regharge it)

Step 4: Some Wires

solder the wires to the AA battery holder - i made the wires extra long on the blue battery holder so i don't mess it up,=)

don't forget the 3th connection!!!

it's the wire that connects the 2 batteries together

i changed the battery holder

Step 5: The Antennae,part 1

glue it with the hot glue gun in front of the holder try to do it as perfect as possible

<-i'm a perfectionist->

try to do as in the picture

Step 6: The Antennae,part 2

with the pliers,bent the paperclip into a straight line.

do your best, =\

Step 7: The Antennae,part 3

cut the antenna with something pointy =)

I used the wire cutter/stripper

you will now have 2 small lines...

Step 8: The Antennae,part 4

with the pliers,bend each line like in the photo

try to make them identical by putting one on top of the other or bending them together

Step 9: The Antennae,part 5

the last part!

glue the 2 metal things on the top of the SDPT switches

Step 10: The Motors

glue the motors at an angle of 40 degrees.

once again,do your best

Step 11: Some Wheels!

i got these from a kinder toy,i honestly don't know where to buy some.sorry

glue it to the back of the AA battery holder.glue it a little lower so the holder doesn't touch the ground.if it does it will not go straight and will go slower

Step 12: Some More Wires

ok so now connect the wires,do your best and look in the picture

Step 13: Some Decoration!!!

be creative!

you can use my model,or create your own!

i also added some electrical tape to the motor for better grip

check out my other instructable!

Step 14: The Circuit Diagram

well follow the pic and connect the wires

zoom it so you can see better

Step 15: How Does It Work?

when the robot hits a wall,it triggers the L or R switch which maked the opposite motor reverse for a couple of seconds.this makes it avoid obstacles

the picture may explain alot

Step 16: Questions

any question,comments,ideas on how to make it better?

post them here!

Can you tell me some more robot models I have to prepare one for school competition can you also tell me steps

Hi, can you please tell me what the "feet" are that you have put on the bottom of the motors?

please can make a clean circuit diagram

i cant make as i dont have the equipment can u tell where i get at home im not allowed to buy these stuff the tools i mean like multimeter and stuff

I'm nine and have not made an instructable, so I want to make one of those robots and cross the antenna. Can I do that? I went to know if you would allow me to do it. Please reply soon!

hi dude,now we are seen ur steps of doing ur robot steps we are doing ur exam but surely we will do my best
