This tutorial is the easiest way in the world to give you a fast start into building robots. And so, it is very easy! This is an updated versio...
It used to be a hassle to buy the materials, because not one single webshop was carrying everthing needed, and you had to buy from several sh...
The 28 pin project board is like a game of Mario Bros; Fun and full of extras and hidden features, making you want to play over and again. It is an ex...
Many times the boards that you buy just have wholes in them, and that makes it hard to plug something in / on. One way to overcome this, is ...
Put these over 2 pins next to each other, and there is a connection between them!
Yes. These are nice. When I started this hobby a couple of years ago, these where really hard to get. Now they are everywhere, and that is ...
You write your robots programs on your computer. Plug this cable into the robot, and transfer the program. Unplug, and the robot runs the prog...
This chip is a Microprocessor. That is often explained as "A computer in a chip". It can be placed in the board described above, whereafter it can be ...
I will describe this later, when we install it below :)
The Yellow chip! It is very dull, is just a row of little resistors. You will be using it to set your board up for servos.
A Servo is a cornerstone in most robotic appliances. To put it short it is a little box with wires to it, and a shaft that can turn some 200 degrees, ...
The one "eye" sends infra red light. The other sees the reflection of this (if there is one), and the unit returns the distance to the object...
1 4 x AA Battery Holder if you are using rechargable batteries, or 1 3 x AA Battery Holder if you are using non-rechargable batteries (Se...
It is very important that your motors have gears. You want a slow robot; Go for high ratios, like 120:1 or higher, as a slow robot is so much m...
Oh yes! If there is something you cannot fix with this tape, it is because you are not using enough! It is a very, very fast way of sticking 2...
Sometimes you do need to solder 2 wires together. For instance the Sharp IR Range finder; It comes with straight up wires on the plug. What you ...
Also needed..
Either 3 AA Non rechargable, or 4 AA Rechargable. This robot needs 5 Volts. Mainly because the Sharp IR, really feels best on 5V, that's w...
If you are new to soldering, this might interest you.
Lighter for heat shrinking, cutter to.. cut. Tip: If you want to use the cutter to remove plastic from cables, turn it this way; Imagine that you...
Can be Mac, Linux or PC. The software needed for this is free.
A multimeter (aka measure-thingey), a wire stripper, and a screwdriver.
First unwrap your board (I am sure you already did that :), and then see that it may have some red stuff underneath. That is just there from w...
Nice, and while you are at it, also solder a pin into analogue port 0, that we are going to use for the Sharp.
Solder a pin into output 0, and you are done with pin-soldering. If it was me, I'd just solder pins in all the holes, but you may want to leave that...
Now, this is a little in-between general instruction :) Connecting 2 wires "The right way" is almost a religion to some. Here is how I do it :) Fir...
Then I solder them together, cut some off if it is too long, and bend it along the side of one of them.
However, BEFORE I do this, I make sure that I have cut off a little piece of heat shrinking tube, and placed it over one of the wires. Then I s...
A lighter quickly heats it up. This makes it shrink, hence the name, and it is a perfect insulation. I don't think you realize how hard it was to tak...
Mount the wheels on the geared motors. You may have a completely different set than I do here, but as long as it is geared motors that runs fine ...
The Picaxe 28X1 Microcontroller that you have here, and the board, is a pretty amazing and very powerful little package. I remember how amazed I ...
In order to keep this as simple as possible, we are just gluing all the parts together, and call that a robot! Yes. If you prefer, of course you c...
Some how also make room for the servo in front. Or stick it on to the front of it all.
Most important is that wheels touches ground, and the rest is more or less in balance. It does not matter if it is tipping a litle backwards. Feel...
Now, as you can see, this time, I use the 4-battery holder. Because that is the biggest one, which makes it easier to stick it all on to it. But.....
- But if you are using non-rechargables, and only should ue 3 batteries, here is a tip: Find an old telescopic antenna, from a radio or something....
Next thing is to place the board on the robot, and hook everything up (apart from the Sharp, wait with that). First: Take out the batteries again ...
Hook up the servo Your servos wires colors may be different, but the hints are; Brown or Black (Ground) to the outside, red (Volt) in the middle, ...
With some (more) foamy tape, stick on the board to the rest of the robot. Make sure the mini-jack (the metal ring in one end of the board) is pla...
There is a nice little room to stuff in excess lengths of wires :)
(Yes, I know that your robot still has no face :)
We need to turn the servo to center. Of course you could try and do it by hand, and estimate it to be in center, but the smarter way is to let the...
Install the driver and cable as described, and plug the jack into the board. nsert all batteries in your robot.. wait.. wait.. sniff.. anything sm...
Plug in the wire to the Sharp, if it was not in from the shop. in other words; Make sure there are 3 wires coming from the Sharp. Your colors may be...
ou should have 3 little black things called Shortening Blocks. What they do is simply conect 2 pins next to each other. If you don't have any, you c...
Make sure the servo faces middle, 150! With a new piece of tape, mount the Sharp IR on the servo horn, facing forward. Tadaa! :) You're done bu...
Programming Enter this code into your editor, and press F5 while the robot is connected: main: readadc 0, b0 debug goto main Now take your h...
- But if you are using non-rechargables, and only should ue 3 batteries, here is a tip:
Find an old telescopic antenna, from a radio or something.
Cut off a piece (Here is a tip on how to cut it), and insert it instead of one of the batteries. Bingo ;)
