Gyrope

Tight rope that auto adjusts to keep walker in balance

Everyone can ride a unicycle now, as nearly 20 years after the invention of the Segway, computationally enhanced gyros control the motion of various "hover" gadgets.

This tight rope setup uses a stiffer than usual rope, perhaps a metal cable connected between two large poles that are able to control the left/right swing of the rope (perhaps by a smart appendage that rapidly pulls the rope significantly right or left) and its tautness based on the adeptness of the walker.

       A triangular box section, perhaps fabricated from aluminium or titanium, point uppermost, would be much stiffer, and more amenable to rapid manipulation by high-speed pneumatic or electric actuators attached at the ends.

       I'm not sure that could go far enough to counteract any oscillation which can be very high energy at a localised point.   

       //triangular box section//   

       With a rigid member the above could be even more of a problem.   

       [ ] I'm going to call ill-conditioned science for now.

       I like it - it's a tight rope after all. A loose rope would be a different situation. But a very, very tight metal cable - that logically could always remain under you. Such a tight cable may be entirely unaffected by a tiny 15 stone mass wobbling back and forth.   

       I think you'd need to always have at least one foot on it though; no running, skipping, or jumping.

       One is never too old for dick jokes.   

       Some utterly safe for work videos linked   

       [bigsleep] -- an utterly rigid human, one that avoids counteracting the rope, is surely not too different from the stick being balanced on any given point, right?

       //is surely not too different from the stick being balanced on any given point//   

       It's very different due to the delay which is inherent in the rope. Whatever material you choose, its going to act like a guitar string - the energy is going to propagate down it with an appreciable delay. You've basically got a transmission line.   

       It's like balancing a stick but there would be a delay from the actuators to adjust the support for the CoG. It gets more complex because like a guitar string the resonance in the cable is going to mess with your next attempt to provide support for the CoG.   

       Admittedly a perfectly rigid human will be of some help.   

       I can't help but thinking the solution to this would incorporate the primary resonant frequency of the rope i.e. the walker would always be in an unstable situation and more or less energy is fed into the next oscillation.   

       It's certainly not an instant bun for hand waving towards having the actuators under the payload as with a Segway.

       // a perfectly rigid human will be of some help. //   

       Hur hur hur hur... ahem.   

       If you sling the rope far enough from the ground, fear will achieve the sort of tetanic muscle spasm you suggest.
