Let's Make Robots!

Patches the robot

Navigate eventualy

This is my first robot im attepting to build, I want it to do the basic things to start with such as to avoid obsticals and such.The base is made of some ply wood i found around my house, lego and two gearboxes i baught from my local electrical store.

The robot isnt to big but not to small either, I intend to add sonar and light resistors soon after getting my robots locomotion in order :).

The microcontroller it will be using is a Picaxe 28A basic board like the one found in the start here guide although mine cant have as much code. (I might upgrade to the X1 soon) :)

here is aditional pictures of my robot (Knowledge bot).



This is my robot so far shown from the top as you can see my microcontroler is just sitting ontop :).


This is my robot form beneath it shows the lego wheels at the back (pointed bit) this is going to act as a caster.

Fron the side

As you can see its no made in lego, i done this because it is now alot stronger and easier to change. There is a front bummper wich will have two switches behind it so that when it hits somthing it can take evasive action!!!.

From the top

As you can see here is the top it is now useing two batterys a 9v and a 6v batery pack, the 9v is for the motors i have made a circuit on two bread boards that controll my motors with a motor controller.

This is the two bread boreds connected inside the robot, as you can see i have used a CD case and used some hinges so i can acsess the insides easily.



Compleatly had to remake this bot apart from the code (it was to heavy).

Here she is now :)

I have recently got a new soildering iron. What do you think i should do with my radio shack one? I am thinking a challange but who would want a used solidering iron for the prize. :(

Hey that is a splendid prize! I sure could use a new (used) soldering iron!!
I'm not to shur I dont even have a soldering iron i broke mine ages ago haha a chalenge sounds good though maybe people will do the chalenge for the sport of it not for the prize ?

I will set up a challange then. Give me some time to work out the small stuff and post it a day or so.

If worst case comes across you can buy a new gearbox.



thanx i might just do that although i must be able to attach some wheels some how ill look into it =]
They where lego but they where all wonkey and wasnt very stable. Also they came loose
What were those wheels on there?
Use your fancy motors that you got.
you dont seem to understand i am using the same motors and gear box from the original, thing is i dont no how to attach anything to the shafts of the gear box.

Here i have used fish tanktubing and some 3mm bored tube but it still slips a little on the axle ive tried hot glue and everything nothings working :(.
