Fluid-based tentacles protect body from a fall.
Inspiration from Nature
When Acyrthosiphon Pisum falls from a leaf, its appendages always land first allowing the insect to roll over safely.
Performances like freestyle running and urban parkour differ from other sports in terms of their training. One may simply gear up and start bating in baseball. There would be no threat to life during practice and professionals’ training sessions often imitate real game conditions. Gymnasts use safety euipment during their training. But parkour is learned out there in the street with no room for mistake. Surely, one starts out slow and performs all kinds of workout. But the actual site carries myriads of factors only available at the site. Adaptability and improvisation are seminal to parkour but a mistake can cost life. A safety gear is needed for parkour performers, one which allows them to practice on tall builds and dense urban fabric with no fear. But it must not interfere with performer’s ergonomics and flow.
A lot of animals have evolved strategies, both deliberate and reflex, to Sustain a fall from a height. Much bio-mimetic research has been done on animals like cat. But this challenge asks for an additional system, sort of an appendage which does not interfere with the natural locomotion of organism. The solution is found in an insect known as pea aphid (Acyrthosiphon Pisum). Every time this little soldier falls from a leaf, its appendages reorient themselves mid-air so the insect falls on them. Appendages not only absorb the impact but roll the aphid over. This strategy is most suitable for free-stylers because it may eradicated their fear withouts having them to compromise on performance.
Technologies such as Robo-Mate Exoskeleton, Omni-Guard Airbag, Fall-protection Safety Suit, Shape-memory Alloys, Magnetorheological Fluids and MagneRide Suspension provide valuable technical insight to the designing of this nature gadget. It is observed that conventional nut-n-bolt robotics create a bulk of equipment. The gear should carry memory fluid which can change its state from liquid to solid and back, in an instant.
Wearable tentacles (2-7) are filled with smart fluid which can change its physical state instantaneously. The gear can sense body movements and built environment. It is able to read (14,15,16-19) geometries of the surrounding and differentiate between human flesh and built structures. It has a default state to which it spontaneously restores (1) which allows an uninterrupted, swift human movement. The tentacles become activated (25-28) only when the back of human body approaches ground surface at a dangerously hight speed, or when human body dropping from a great height, front-faced or side-faced, can use some assistance in rolling over at the point of impact (like an aphid). Liquid-based exoskeletal tentacles change its state slow-enough to provide cushioning but fast-enough to restore promptly.
