Anti-Land Mine Robot

I have started design and concept design on a robot to mark (via GPS and UV paint) and destroy unexploded ordinance in Cambodia.  I am assembling teams for various aspects of the project (mechanical, electronics/power, practical application, coding and programming, construction, etc).  While many people have offered their experience and knowledge, the more people contributing can only benefit the end product.  This is not a money-maker, it's a life sustainer.  I'm looking for people who are interested in using their skills to better someone else's existence.   Though it is brand new, you can visit the project's blog at   All advice is welcomed.  Project updates will be regular. Thank you for your time, Huck

1st time robot. Too ambitious?

Hello All, I have recently started an ambitious project. There will certainly be much learning along the way.  But it is too ambitious? The goal is to build a bot that can be controlled remotely, to aid in the detection, marking, and ultimate removal of unexploded ordinance in Cambodia (in this first application).  Though I have never built a robot of any type, I am quickly learning the basics, but would like ultimate beginner advice if anyone had any.  If anyone would like details on the project, PM me.  It's really a lot for a forum post... If there are any Veterans or military buffs out there, I could really use other first hand accounts of experiencing UEO. Through generous donation and aquisition, I have come cross an electric wheelchair, and many parts needed for a former "Battle-Bot".  Battle-bot turns peace-maker.  I love it!  The motors are Bosche, 24V and ~750watts.  Included were DC motor (high amp) speed controls, and 2x 12v 26A sealed lead-acid batteries.  Very very excited to really dig in.  I lack a quality track or model of a good track to use for traction, etc.  Anyone know of any good and sturdy RC tank tracks I could look at for design or actual construction? Though I began to construct my own track out of sheet metal and various materials available (it actually turned out kinda ok), I don't intend on reinventing the wheel, as it were.  3" took me almost 2 hours. Will also be incorporating a ~3'-4' rotating and articulating arm.  Trying to keep its weight to under ~30lbs.  The wheelchair frame is very strong and moddable, Ws thinking of using a lazy susan type bearing, but I'm not sure I could find one rated for that weight for an affordable price.  Any suggestions? Thanks for checking this out.  Again, if you want more details, I'm happy to share my plans.  Just PM me. This is being designed 100% open-source, and 100% documented with a video and written journal in order to be easily duplicated.   Constructive criticism is NOT personal criticism! Huck

How did the wind powered generators work THAT WERE MADE FOR some African primitives?

Some of you failed to even read the one line question:  "How did the wind powered generators work THAT WERE MADE FOR some African primitives?" They were made by an international humanitarian group.  Did you notice that the article on this mentioned that the one watt LED light caused the birth rate to drop by one third? Thanks for the great answers that I got from those who read the question.
