X6 Hexaped, walker. Outdoor testing. The cold had a bit of a slowing of the pneumatic parts. This was the first test out doors in the dirt. A work in progress. This versions main concern was to try to get all the parts inside as compared to the first. http://mindstorms.lego.com/nxtlog/ProjectDisplay.aspx?id=427742ff-fefd-45a4-bca1-8c20d0984d83 http...

Prototype Roadster Inline 4 pneumatic. With power Function steering and battery box. Few things noticed after this was the steering is much to fast needs to be 3x slower is 9;1 maybe 24:1 will work better. The rims are slipping on the tires rear. Need to crazy glue them for faster take offs.

Terrain testing the TriTrax on steps, gaps and a hill over a edge

Full walking gate with rotating ankles. Wall avoidance programming. This is the third walking program i have came up with. First one that makes use of the turnning ankles. work in progress... more details: http://mobildefencelab.blog.homepagenow.com/blog.shtml http://us.mindstorms.lego.com/nxtlog/ProjectDisplay.aspx?id=8eac3bb9-f3ac-4cf0-ae50-920...

IT the STiX-2 testing my new double knee joints. To be used someday in a biped.

My secound run with my Biped, a few changes in the program and a few mechanical changes. Shaves about 2 mintues off the run. New time 53.15 seconds. Not sure if this design will go to much faster with out falling over.

Testing a 360 degree of rotation double knee.

this is a very strong puching "thing" It is not really 222Doc quality, ( i mean im not a rocket scientist!) the high tourque reduction in the treads has its pros and cons: pros: provides extra torque and power. cons: slows down...Duh.. and provides turning but no reverse! i used a technic motor because i didnt want to take apart my halloween robot....

this is my first EVER working biped. the first one i made dident shift its weight and blew up in to a billion pecies after it fell off my table. i was inspiered by the work in progress X2 biped by 222Doc. this biped is shaky and unstable, but at least it can walk in a circal. as you may know, walking on two feet is an extream for us and is very har...

Modified lego pneumatics

lego shape printer simple printer made from Lego Technic and NXT Mindstorms.

My latest prototype of TriTrax. Testing basic functions and mechanicals with Blooth and IR remote. Soon to be autonomouse, a work in progress.

IT is a prototype walking stick, in early programming and design

Early this year I had the pleasure to design and build a couple robots for Dave Astolfo's new book, 'Building Robots with Lego Mindstorms NXT". This is my favorit of the two I did. This only uses the NXT retail version parts as well.

Lego PF IR system 8 function testing. 5 dof arm tread base with two speed trans@2;1 and 10;1

My entry at nxtasy#4. A line following biped. programing still need to improve

Tilta-A-Ped's mechanical features over view.

My entry for nxtasy's challenge. My design was to try and build the lightest possible bot to get the maximum ratio. Though in the end i was not near the leaders I am happy with the lightest bot in the challenge.

Testing how well a pneumtic V8motor could power a small roadster. Since it must have a outside air supply somewhat will limit its use to a noviltiy. I can go faster but the Lego univerial joint wil snap under the torque

Tri-Tracks goes UAV full autonomous operation. First autonomous navagation of the Plano Box step pyramid.
