Soft Pneumatic Exoskeleton : V 01 Test



After the first round of testing, I realized assisting jumping with pneumatics is nearly impossible. The size of the tubes and tank necessary to get a high enough cfm to actuate the air muscles at the speed of jumping seems too large for a lightweight wearable application. So, I’m going to concentrate on assisting walking. Maybe speed walking.

  1. Hey Che-Wei, I was wondering if you could give me some advice on air muscles since your the only person I’ve found that actually has a working system. My main problem is the tank. I’ve looked at using a nitrogen paint ball tank, because it can store a whole lot of air, but I’ve had some problems with find a valve thats strong enough to hold the pressure. The only ones I could find were too expensive. (Here’s the post ) Would you mind posting the type of tank and valves you used and a rough estimate to how long the tank lasts? Any help I can get would be great.

  2. I ran into the same problem. I never finished the high pressure tank system. I was using a pony scuba tank, but with low pressures around 160psi. The best potential solution I found for using it at 3000psi was to use scuba regulator that could regulate it around the 80psi range. You can find some old relatively cheap ones on ebay. I never tested it though.
