Does it replace the locking pin wed be forced to use?
Instead of us having a bracket or pin to prevent the arm from moving, maybe they have a valve to prevent the gas from getting into the cylinder in the first place...
I guess it could be slightly safer, with the dump valve open, and that ball valve closed.. if theres a misfire there wont be the strain on the locking pins?
The bot is being entered in Motorama ......Al Kindle is the safety official.
I personally cant see the need for the valve ...... but .......Al of course has the right to impose any safety features that he decrees necessary.

Rob, it is inherently unsafe.
A Burkert needs a pressude differential of 1 bar to close down perfectly In a normal system the size of the hoses and resistance in the system gives this valve the chance to do its job, withoud endangering anyone.
Combine it with a screw valve on the bottle opening slow and the Dantomkia/ Bigger Brother style extended ram locking pin nothing can happen, even if the burkert failed.
Put in a ball valve in between the main valve and the ram reduces the size of the system downstream, acting like a initial buffer, as it would fill with CO2 at full pressure. Opening that ball valve would send in a rush of CO2 bigger than the trickle normaly could happen.
According to me, the safetyguy there is just grasping at straws to avoid the dangerously explosive high pressure pneumatics
Looking at the layout the ball valve will be under the flipper arm. So that means you have to stick you arms into a loaded robot to make it safe. It would be much safer to have a locking pin which you can sneak up behind the robot to insert. I think the saftey official has made the robot more dangous to turn off then if the valve wasnt there.
Actually if your arms are in the robot under the flipper arm trying to turn it off, where is your head? Oh, I dont like that at all.
I am with you guys. . . I dont like it at all. It just adds about 8oz that I could use for something else. But, I have to have it. So I got over it and in the bot it is. I hope to have the armor done this weekend and maybe part of the arm. . . Pics as I get stuff done.
Got the base plate milled out today. So now I will wire it all up, install everything and then this weekend I will do the arm and the armor. Pic on profile.
Cant wait to see a video of it during battle.
Put a new picture of it up on my profile and look at the yahoo page for all of the new ones. I have to wake up in 6 hours to go do the armor and finish up the drive. More pics tomorrow night.
Did the armor today might do the drive later tonight if I get the energy. Pic of profile and yahoo page.
How come you put the grinder over everything but your welds?
