Don  Lancaster's Guru's Lair  Flutterwumper Library
auctions bargains books contact email home library map ?new? rss

Flutterwumpers are low cost machines that spit or chomp.

Such as printed circuit drills, sign routers, animation stands,
CAD/CAM mills, plotters, Santa Claus machines, etc. A new
approach to designing these machines involves both the PIC
microprocessor and the PostScript computer language.

This library shelf holds tutorials,  resources, and application
notes you can use to build yourself a flutterwumper. Such as
a $100 printed circuit drill or a $200 Santa Claus machine.

Also included are links on Hexapod devices. This is a stunning
new method of machining that involves no sliding friction or any
side-loading. For elegant simplicity and dramatically lower cost.

Most library files require an Adobe Acrobat 4.0  plug in for online
viewing.  Offline, these may be accessed by an Acrobat Reader or
an eBook Reader or any other .PDF accepting program.

Hexapods are a brand new method of "virtual ways" machining, using
"pushme-pullyou" techniques that make use of mostly linear
translation and very little wear. They are revolutionizing machining,
materials handling cranes, telescopes, vibration isolation, and robotics.

Note that some six legged robots also use the term "Hexapod" in
violation of Hexel's trademark's. These use a different concept.

Hexapods are also sometimes called Stewart Platforms or Parallel
Link Manipulators.

Here is the main Hexapod manufacturing site...

Machine Tool Supplier Hexel       Manufacturers parallel link manipulators for machine tools and      various special applications. A normal robot uses six series axes;      these use six parallel ones for simplification and improved accuracy.

And the main web info gateway...

Parallel Mechanisms Information Center ParralelMIC       Includes databases for related publications and patents, as well as a      terminology list. Also hosts the ParalleMIC newsletter and has      a book, publication, and reprint store.

An excellent and extensive link farm is found here.
