Tinkering with Lego Technic

Lego Technic is a Lego based technology that includes a combination of totally new kinds of Lego pieces and fancy technology that lets you build some amazing things. You can get kits that range in cost and sophistication from the LEGO 8514 Technic Power Roboriders a sort of motorcycle for robots that costs tens of dollars to a Motorized Bulldozer that will set you back nearly $700. Actually, I think there may be Techno kits that cost way over $1000.

The modified Lego pieces include the techno "brick" which comes in many forms that have holes in them through which specially shaped parts can be inserted, to have an armature that does not rotate, an axel, or some sort of pivot. Some of the tecno Lego parts seem to converge on Erector Set pieces, but without the annoying little nuts and bolts. Then there are gears and pullies and all that stuff, and on top of that, electronic doohinkeys. You can get electric motors, you can get a differential, and clutches. You can get lights. There is even a pneumatic system. Actually, there's two different ones, a legacy system and an updated system.

With enough parts and some good design, you might actually be able to design a Lego Technic machine that does something useful. Like one that brings you a beer or scares away solicitors at the front door.

I've got this book that seems to be the book to have if you are going to start messing around with this Robotic Technology: The Unofficial LEGO Technic Builder's Guide. If you know someone who is planning to play around, er, I mean engage in DIY hobbyist activities, with this form of Lego, do them a favor and get them this book so they can mix and match and design their own stuff rather than buying those expensive kits. Some details from the publisher:

The Unofficial LEGO Technic Builder's Guide is filled with building tips for creating strong yet elegant machines and mechanisms with the Technic system. Author Pawel "Sairel" Kmiec will teach you the foundations of LEGO Technic building, from simple machines to advanced mechanics, even explaining how to create realistic to-scale models. Sariel, a world-renowned LEGO Technic expert, offers unique insight into mechanical principles like torque, power translation, and gear ratios, all using Technic bricks. You'll learn how to:

• Create sturdy connections that can withstand serious stress
• Re-create specialized LEGO pieces like casings and u-joints, and build solutions like Schmidt and Oldham couplings, when no standard piece will do
• Build custom differentials, suspensions, transmissions, and steering systems
• Pick the right motor for the job—and transform its properties to suit your needs
• Combine studfull and studless building styles for a stunning look
• Create remote-controlled vehicles, lighting systems, motorized compressors, and pneumatic engines

The The Unofficial LEGO Technic Builder's Guide, being unofficial, is not a catalog or sales pitch, but rather, a very well organized and clear guide to getting the most out of your new toy, er, hobby. Start at the beginning, work towards the end, and you'll be an expert modeler and maker of things Lego-Technic. Nothing that flies, though. But a lot of stuff that drives.
