This seems like a poor fit for VR motion simulation - actual movement through space is generally unnecessary, you just need to gimbal the platform to simulate accelerations. Actual linear acceleration is of limited value in simulation because you can&#x27;t maintain that acceleration indefinitely - you run out of room and have to apply an opposite acceleration, which can conflict with the simulation needs.<p>On the other hand this looks more useful for something like movie making, to throw actors around in front of a greenscreen.

If you like this, lookup &quot;6DOF platform&quot; - there&#x27;s an active scene of people who tinker with home-made motion platforms, primarily for simulator games. Some <i>very</i> impressive stuff there, e.g. <a href="http:&#x2F;&#x2F;motionsim.blogspot.ch" rel="nofollow">http:&#x2F;&#x2F;motionsim.blogspot.ch</a>

The concern I have is that failures in the control software or mechanical failure would have grave consequences. Maybe that&#x27;s a solved problem and the cable capstans have mechanical arrestors that kick in, etc but the setup looks inherently unstable unless under active computer control (due largely to the crossed cable attach points).<p>This is quite a bit different than a more typical hydraulic setup where an unpowered&#x2F;uncommanded state simply leads to the platform settling in a stable configuration.<p>Having said that: I still want one. :D

Cable Robots are generally a very interesting technology. I wrote a bit about them (eg. for 3D printing, as a crane, etc) a while back: <a href="http:&#x2F;&#x2F;www.hizook.com&#x2F;blog&#x2F;2014&#x2F;07&#x2F;15&#x2F;stadium-sized-3d-printers-using-winch-robots-aka-cable-robots-or-rope-robots" rel="nofollow">http:&#x2F;&#x2F;www.hizook.com&#x2F;blog&#x2F;2014&#x2F;07&#x2F;15&#x2F;stadium-sized-3d-print...</a>

I purchased a commercial motion simulator as part of research for a vr tech we&#x27;re working on and while you can immediately see the potential, it&#x27;s not quite there yet.<p>Some resources to share<p>If you buy a simulator - offsetting to the chair with the rift is a work in progress <a href="https:&#x2F;&#x2F;forums.oculus.com&#x2F;viewtopic.php?t=7933" rel="nofollow">https:&#x2F;&#x2F;forums.oculus.com&#x2F;viewtopic.php?t=7933</a> - and not currently supported in the Oculus SDK.

Multiple computer-controlled winch systems have been used for movie special effects for years. Here&#x27;s a 2010 system test for a flying taxi, which shows the controller as well as the taxi.[1] Disney&#x27;s Aladdin at Tuacahn Amphitheater has a magic carpet which flies out over the audience with two performers on it. That&#x27;s done with four computer-controlled winches.<p>The robot simulator looks like it&#x27;s using the same winches Kirby&#x27;s AFX uses for theatrical work. That&#x27;s not surprising; few companies make high speed precision-controllable winches rated for human safety.<p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=VkjM9leyQPc" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=VkjM9leyQPc</a>

Looks a lot like University of Iowa&#x27;s National Advanced Driving Simulator NADS-1 [1]. NADS-1 has an entire dome on tracks, hydraulics and a bunch of other cool stuff going on. I guess it&#x27;s used mostly for research.<p>[1] <a href="https:&#x2F;&#x2F;www.nads-sc.uiowa.edu&#x2F;sim_nads1.php" rel="nofollow">https:&#x2F;&#x2F;www.nads-sc.uiowa.edu&#x2F;sim_nads1.php</a>

I didn&#x27;t see any Yaw motion in this video. (Rotation about the Y axis.)<p>Does it support it? Is it not necessary for the motions they&#x27;re trying to induce? Would you have to make the seat rotate on the platform?

I want one. I&#x27;ll replace the walls&#x2F;stairs in my house with this and just zoom exactly where I need to go. Think of the space savings; I could mount my computer 6&quot; from the ceiling!

This would actually be dope for flight training. As a student pilot there are some things like unusual attitudes training, that rely on motion to fool the senses.

I&#x27;d like to know more about the winches, since they aren&#x27;t made for constant use. They have planetary gears with very high gear ratios, which can overheat if used too long. I believe many linear actuators (with high gear ratios, used to lift beds&#x2F;tvs) have ~20% duty cycle (use for 2 minutes requires 8 minutes of cool down).

it looks really cool, however with cables wouldn&#x27;t this limit the amount of &quot;instant Gs&quot; you can generate? it seems motion simulators based on pistons would be able to simulate better things like driving on a bumpy road and sudden changes of direction as there isn&#x27;t the slack of the cable to take into account or the inertia of a large suspended mass (cables are heavy too)<p>Still given enough space and light enough cables that support enough tension (to minimize slack) it seems this could be scaled up very cost effectively compared to other technologies to enable longer sustained accelerations

Hopefully not a completely ridiculous question, is there any chance cable technology like this could be used as public transportation in the future similar to in Pixar&#x27;s Robots?

Cool, it&#x27;s the same concept as the NFL skycam! I wonder if there are any practical uses for it, say military or civilian training?

All well and good with the standard little girl model, but what does this look like with ten fat disney tourists? What would the machinery look like to swing 10 or 50 times the weight? (Same question if this is to be used for flight simulators.) Is there a point at which linear hydraulic actuators are easier?
