Walker Ver5.3
This is extracted from a guy who is good in designing a BEAM robot; four legs walking robot ( using five motors). He claimed that this particular robot is his third generation five motor walker and he had fine tune the system.
He said that this walker is absolutely incredible to watch and it pushed him through the barrier between building BEAM toys and building a true robotics research platform. Look at that wires use for the experiment. As I have said earlier, you have to be really interested and have the patience to go through this time consuming experiment and don't give up. The good thing about this experiment is that you learnt a lot by doing rather than just reading i.e. theory.
Very interesting isn't it. To know more of his Beam creation Robot walker, kindly visit his site at :

Tools for desoldering?
I've read an articles from the net about the subject desoldering. This guy was having difficulty in desoldering despite using all the necessary gadgets such as solder pump and copper wick. Well, there are many factors that affect desoldering, one of them is the solder iron it self. If the tips of the soldering iron is not clean prior to using it, you will for sure face difficulty. The soldering bit will not properly melt. One way to clean the bit is by rubbing it with a damp sponge. You will notice the clean shining surface once the bit is clean. The solder will melt fast and make it easier for the solder pump to suck it.
Another way is to use the technique
"Whack-it". However please be extra caution.
First of all, you must apply safety precaution such as:
- Wear safety glasses.
- Your work surface must be prepare to accept slight abuse.
- You should not do anything that might injure other people nearby when using this technique.
now lets start, heat up the solder iron and heat the solder connection, then rapidly smack it down against the work surface ( did you read the second requirement above? just to make sure you understand what I meant).
The molten solder will fly out, hit the surface and harden into a metallic splatter mark. Never do it directly in front of your face - hold it off at an angle so that there is no chance that back splash might come back at you. Although this is leathal, it sure the quickiest way to get rid of that stubbond solder out of the PCB. Anyway use it as your last resort if you get really annoyed or you feel impatient. But again please be careful. You are free to use this technique at your own risk. No one to be blame if you injured yourself except you yourself.
For those of you (robot builder) out there who need more information or perhaps a complete documentation to help you build a Robot using beam technology, kindly visit the following link below:
SOLARBOTICSApart from those useful document, the site also provide you with plenty of parts, spare part for building simple to advance robot. For the beginners, it may take you a while and plenty of experiment to fully able to understand the mechanism or how the all system works together as a complete functioning robotic that can move, jump, sprint, crawl and so on and so forth. Building robot does not require you to have a formal education in electronic engineering. What important is that you must like robot and always want to know more about robot, be it simple or advance robot. Be willing to spend your time to read, study, experiment, and most importantly build them yourself. There are plenty of books, info, articles in robotic, in the net you can find thousand of documentation, in fact some site give a free tutorial with pictures, to show you step by step on how to build yourself your very own robot.
Until you have successfully build your own robot, you will not know the feeling of excitement and the feeling of deep self satisfaction, as if you have given a life to these miniture mechanical creatures. Robot have always and will always facinate me ever since I was a boy.
