Sorry guys. If u mean model ''Nemesis'', there is no RC part. Everything is cotrolled by hand. Thanks!

Very nice.

Very nice!

Nice!!

Nice one!

Cool!

Cool!

Indeed! About 100 hours, quite complicated.

Dear all, For the pneumatic contest, I've built a huge robot called ''Nemesis''(from the ancient greek goddess) and I would like to share it with you. Nemesis has 22 pneumatic functions operated by a double compressor. All pneumatic valves are operated only by hand according to the competition. free image uploading Total air cylinders : 26 large 11 mini The compressor uses 2 large pneumatic pumps operated by a PF XL motor. upload photos The maximum pressure that can be reached by this pneumatic system is 28 psi with fresh batteries. Due to more than 30 pneumatic ''T-pieces''pressure cannot reach a higher level because there is a huge drag and the XL motor has no power to rotate more. The length of pneumatic tubes are between 0.5 and 1.5 meters long. Due to the large hoses, large air storage is needed because there is a lot of air loss in the system. The air of the whole system is stored inside 2 lego air tanks (although the system needed far more) : screen shot windows how to screenshot on windows 7 The compressor has an auto-pneumatic switch using a large cylinder, which turns the air engine off when the pressure reaches 24 psi. upload gifs A manometer is used for showing the air pressure at any time. free photo upload Functions : Nemesis has 2 arms. The bigger front arm has 15 pneumatic functions and the small back arm has 5 pneumatic functions. The small back arm has the following movements : a) small gripper imagehosting b) elbow1 c) elbow2 d) shoulder e) shoulder rotation The huge front arm has the following movements : a) large gripper, operating 10 fingers independently having 2 mini cylinders each b) wrist, operating 2 functions (up-down and turning) c) elbow d) shoulder e) shoulder turning Besides, the robot has 2 more pneumatic functions : 1) Face movement 2) A third gripper which is mostly for fun (e.g. for scaring house cats) Here is the video of the project : Thanks for watching Good luck to everyone!

Ok...I see. How can I make visible links without having to click on them? Photos have high resolution.

Hehe I believe you. Everything depend on willingness Is a crane the most suitable vehicle to support this tremendous amount of functions(32 would be like a record)? Or should you think of another type of machine? Anyway, it's extremely challenging
