step 13FINISH!

CONGRADULATION!

You made you first Beetlerobot!

Cross your finger, put the AA into the battery holder and but the robot on the floor...

Does it work?

to stop it, you can step on it or simply remove the battery.

You can add some decoration to the robot. I took some big plastic shell find in the 2$ vending machine. I took one half and added sticker!

to debug the robot go to my website
http://beetlerobot.solarbotics.net/debug.htm
It is in French and you will understand. You made a robot, you can read French now! :P

Oui = yes
Non = no
Est ce que les moteurs tourne? = does the motors turn?
Est ce que votre robot avance tout droit? = does it go in a straight line?

ok ok
I have added other steps to explain more about the robot and a also added a debugging section.

You can ask questions in French if you want too.

step 12melting some shoes...

step 12melting some shoes...
Take the heatshrink and shrink them on the shaft of your motors. Use a lighter to attach them.
Yo can put more layer if you want to, different colours.

I even saw some people use hot glue stick on the end of the shaft. They took 1cm of the glue stick and attach it directly to the shaft. BEWARE, you robot wil be VERY speedy and it might destroy itself on the first obstacle it will hit.

step 11the antenna!

You are going to give your little robot some way to feel the world.

Take the small paperclip and bend them to form some antenna.

Glue them on the metal plate pf the SPDT switchs.

I don't recommend soldering them because you need some aggressive acid-based flux or silver solder. If you don't have any experience in soldering, you will melt them.

I have already solder some using silver solder.

step 10soldering the brain

Here is the hard part, soldering each wire. Look at this picture and do the same :P

One thing that I forgot to do back then, was to use different colours for the wires to simplify everything.

with some special software I was able to achieve that.

Step 9 the back caster

Here you are going to make the third wheel, the back caster using a plastic or wooden pearl.

You can make something fancy or very simple. I took the BIG paperclip.

If you can not find a wooden pearl, you can use the paperclip directly on the floor. It will work but might catch on stuff while rolling around.

step 8 glueing the motors

Glue both motors on the battery holder

Make sure they spin forward...

I have just realise that this does not make any sense at all! :P

Look at the third picture how you can angle out the motors for speed.

step 7glueing switchs

Glue your switchs on the battery holder in a V shape.

Don't forget to put the blue "third connection" wire in front.

I have found a much more efficient way to but the switchs on the battery holder.
You can glue them in a A shape so both antenna cross and will not get stuck in a leg chair.
