I'm going to try and use the pneumatic system I have spare and I have nearly all the parts to make a bot so I'm thinking what the hell but I'm trying to think of ideas for a double acting ram
So far I can think of a axe, front hinged flipper or a 4-bar flipper
Any other ideas for one?
Grabber/lifter?
TAN style?
Difficult to do in 13.6kg
Any others, I don't really want to go for another flipper, something a bit different would be good
AXE :proud:
I might do it battle axe style coz I got Wana fart about with rack and pinion stuff
what!? :|
Battle axe uses chains and sprockets etc which I would probably do :)
I'd love to see a 4-bar lifter. Don't see them around much anymore. When done well they're better than rear-hinged flippers for launching, it would seem. :)
You could do a pneumatic spike but I doubt it would be very effective. Or a horizontal axe/hammer which again wouldn't work to well but I think would look cool.
Im leanig towards an axe yet a 4-bar lifter would be nice if it was built to self right
ah i see, a similar system is used on saint if i remember correctly. it was the 'got' in your sentence that confused me.
My only issue with a lifter is do they self right properly or would it need to be invertable? I'm not too sure on the 4-bar lifters but I think it would need to be invertable
If it's powerful enough, as in a hard punch, I would have thought it would self-right. And, I'd try and go for invertability (is that a word?) anyway. If your motors are mounted in the middle (in height) of the robot, all you need is some thinking about gear ratios, 4 or 2 holes and bigger wheels, right? :wink:
a bit like merlin but 4-bar lifter instead of the bar flipper?
another axe would be nice :evil:
im fairly settled on an axe since the ram im using is only 40mm bore, i wouldnt chuck much oput with that if it was a 4-bar lifter
