How to Make a Very Simple Robot

P7162475.JPG
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

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

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

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)

Some Wires

P7062420.JPG
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

The Antennae,part 1

P7062419.JPG
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

The Antennae,part 2

P7062421.JPG
with the pliers,bent the paperclip into a straight line.

do your best, =\

The Antennae,part 3

P7062422.JPG
P7062423.JPG
cut the antenna with something pointy =)

I used the wire cutter/stripper

you will now have 2 small lines...

The Antennae,part 4

P7062424.JPG
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

The Antennae,part 5

P7062425.JPG
the last part!

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

The Motors

P7062426.JPG
glue the motors at an angle of 40 degrees.

once again,do your best

Some Wheels!

P7062427.JPG
P7062428.JPG
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

Some More Wires

P7062411.JPG
ok so now connect the wires,do your best and look in the picture

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

The Circuit Diagram

well follow the pic and connect the wires

zoom it so you can see better

How Does It Work?

beetleBot-2a.jpg
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
