UPDATE: WooT! Found the full paper on the project, man this thing is complicated :) See atachment, print it to have something to read those cold winter nights ;)
Heck, I just want to know what the pump and the valve are / where I can get them :)

that’s sweet!

Nice one! I think he’s
Nice one! I think he’s “charging” up the bottles with some sort of gas and releasing it to jump, maybe with a solenoid valve?

From New Scientist:
Powered by compressed air stored in two 2-litre plastic bottles, the ram - an aluminium cylinder - is fired to launch the robot to the required height.
Air Valves
OKay, I have a car tyre valve glued to the side of a 2L PET bottle, and an outlet at the cap. It’s hooked in parallel with another one with an inlet and an outlet. Loads of plastic hose. I can pump it to 7 bar pressure with a car tyre pump. Currently holding well at that pressure. Too scared to put more.
Yes, of course I filled one of the bottles with water to see how far it would scoosh! It scooshes FAR! I think we have next summer’s water pistol sorted out!
Seriously: Can anyone find a valve which can be actuated rapidly enough for this robot to be workable?? I can only find really slow ones for really low pressures.
I LOVE the idea of the spring suspension built into the wheels. THAT has to be applicable to any robot.
So cool!
So cool!
Bimba, folks!!!
C’mon, you guys should know this…
Bimba is the guru of pnumatic stuff!
All wicked cool info… But
All wicked cool info… But where are the pumps? (and I am not talking about high heels)
How on earth does one get that high pressure that fast, with such light weight?
Another that can recharge?
Here’s a spring version, operates a little differently, but seems to self power more. (Wait for second robot description)
