 | | 8455 Alternate Model - Pneumatic Biped
|
|
I finally got some pictures uploaded of my biped made from the 8455 set. This model is built from the parts of one 8455 set. The hoses are not from the set, so your colors may vary. It took quite a while to find geometries that work using the 8455 (...) (22 years ago, 30-Oct-03, to lugnet.technic, lugnet.robotics)

I've gone ahead and released a new version of BricxCC. Get it while it's hot! :-) There are a few rough edges in this release, primarily in the pbForth console. Also, the leJOS .hlp file was so large I did not include it in the main installer. The (...)
