A few weeks ago Krasnaya Zvezda run an article about the new parachute  system called Stayer by AO Polet. Russian Ministry of Defence has completed the testing phase of the new system. If approved, Stayer  should enter service in the next year.

Not sure why Russians are worried about what looks like some middle aged EM, who is more likely than not, looking at porn.

It looks like a private company decided to enter the market, which is occupied by enterprises of the Defense Industry Organization of the Ministry of Defense of Iran.

Let's see what they will do after testing of gear will be done.

And the article completely glosses over unpowered exoskeletons. Based on the paper below, it seems like there are plenty of challenges in designing a good unpowered exoskeleton, but it is encouraging that the weight and inertia of a 11.7 kg passive exoskeleton only increases the "metabolic cost of transport (COT)" by 5%.  

 

http://biomech.media.mit.edu/wp-content/uploads/sites/3/2013/07/Walsh-2007_A-QUASI-PASSIVE-LEG-EXOSKELETON-FOR-LOAD-CARRYING-AUGMENTATION.pdf

 

"Metabolic data show that the zero-impedance exoskeleton increases metabolic COT by 23% compared to the loaded backpack, and 12% compared to the quasi-passive exoskeleton, highlighting the benefits of spring and variable-damping mechanisms at the ankle, knee and hip. Finally, the added-mass condition increases the COT by only 5% compared to the standard loaded backpack, suggesting that added mass alone cannot explain the 10% COT increase caused by the quasi-passive exoskeleton."

 

"One might expect that the added mass and inertia itself might fully explain the COT increase of the quasi-passive system. However, as noted in the results (Sec. 7), the added-mass condition only increases the COT by 5% compared to the loaded backpack. What might be the cause for the 18% difference between the zero-impedance exoskeletal COT and the added mass COT? Since the joint springs are removed in the zero-impedance case, the increase in COT cannot be attributed to a destabilization of the wearer’s walking pattern due to the release of stored elastic energy. Further, since active knee damping is not utilized on the zero-impedance exoskeleton and friction in the joints is minimized by the use of high-quality bearings, energy losses at the joints of the exoskeleton likely do not substantially contribute to the 18% increase in COT. We therefore conclude that the dominant causes for the observed COT increase are added mass and kinematic constraints imposed on the wearer."

 

"More likely is that the exoskeleton applies kinematic constraints on the human wearer due to poor collocation of the joints and/or a restrictive interface between the exoskeleton and operator, forcing an unnatural, inefficient movement pattern. It has been shown that changes in natural gait increase the physiological energy expended during locomotion."

 

Mawashi seems to be developing a much more advanced exoskeleton, at least in terms of ergonomics. It would be interesting to see what a collaboration with Bionic Power could yield with respect to an exoskeleton that is quasi-passive/energy-harvesting.
