Pneumatic

thanks for the nice comments guys! :) Tho my shop is usually a massive mess! I did a little more work on it today on my day off. I have to go to class for the evening, but I will probably work on it more when I get home. I will mill the other belt slot, lathe a new piston, and lathe a support for the arm mounts. Then all I really have left is to make the arms and armor. In that order. Weight is looking good.. A few new pics.

And more work still today! Did a little CAD (cardboard aided design) and got the shape or my armor set out. When it is all said and done I will have about 10 pounds left for the arm and armor. Version 2 of the bot will be alot better on weight, but I think 10lb is enough to have 1/4 AL armor with Ti bolted to the bottom few inches. look on the yahoo page for pictures.

Do you forsee any problems with .......what appears to be .......an offset cylinder and flipper pivot arrangement?

nope... But it could happen. We shall see.

Would create a twisting force and therefore more friction methinks, but then again I havent seen what linkage layout your gonna be using.

looks like it wasnt designed to have the ball valve in between ram and valve that would bring it to centre if not

That is true. I did not want to have that thing in the system. But the safty person at the event that I am going to said that I had to have it :-\

The arm is going to be rather beefy to make up for the twist that will be going on. The next frame will have a different tank layout so the shape will be alot different.

Nope. I did not want to have that ball valve, but the safty boss at the event that I am going to go to says that I need to have it. Inorder to try to keep the whole thing from twisting I am going to make the upper arm really beefy. . . Might work well, might suck. I have no idea! We shall find out soon enough.

Can you or that safety official from the event explain to me what possible use that ball valve has?
