I was playing with pneumatic piston and switch linkages trying to improve on the geometries I've developed in the past. This lead to inchworm 4. http://www.brickshelf.com/gallery/kclague/inchworm4/sta_0764.jpg Inchworm 4 has two waves travel down its body like inchworm 3 http://news.lugnet.com/technic/?n=16051 The big difference is the design of an individual body segment, which ends up looking like a 7. A typical linkage involves a beam running parallel to the piston, with the piston offset from the beam and hooked to a switch. http://www.brickshelf.com/gallery/kclague/inchworm3/hpim0057.jpg Inchworm 4 has the piston in-line with the supporting beam. A lever hooks the piston to the switch, as seen here: http://www.brickshelf.com/gallery/kclague/inchworm4/hpim0051.jpg The orange 1x5 thick beam in the middle is the lever that hooks the piston to the switch. This new design makes for a very sleak and simplified than that in inchworm 3 (IMHO). There are more pictures here: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=291660 For some of my old and dear friends, please notice the use of a wide variety of colors (does John Barnes have enough time to read technic anymore?)

Looks great! How about some video so we can see how it works? (17 years ago, 26-Dec-07, to lugnet.technic)

Kevin! I am astounded by your recent creations. I intently tried to figure out how you made these inchworms. The gates that you are so well known for are so elegant yet complex. The work you have done is a marvel to see! So you were able to get a 1 (...) (17 years ago, 11-Jan-08, to lugnet.technic)

(...) Hi Kevin, Thanks for posting these amazing projects! I have been stuck at home recovering from a severed Achilles tendon and was looking for something new to build. It is always fun building your pneumatic creations. bob (2 URLs) (17 years ago, 11-Jan-08, to lugnet.technic, FTX)
