After months in a pandemic lockdown<\/a>, it seems somewhat normal for everyone in the home to sit in front of screens all day, whether we\u2019re on video calls for work or gaming for entertainment. But all of this sedentary activity could lead to increasingly poor health outcomes\u2014especially if our habits persist in the post-pandemic era<\/a>. That\u2019s why Ethereal, a VR startup led by founder Scott Summit, is working hard to reinvent personal fitness for a world that craves digital escapism\u2014with the help of generative design<\/a> tools.<\/p>\n\n\n\n

\u201cVR has a unique ability to steer our addiction to digital entertainment more productively,\u201d says Summit. \u201cWe want to turn gaming into a full-body experience, one that takes place in an unlimited interactive environment, one that simulates any number of real or fictional worlds.\u201d<\/p>\n\n\n\n

Summit envisions fitness games where players race up the Eiffel Tower<\/a>, battle each other as walking robot tanks or go paddleboarding in the Caribbean. \u201cWe can recreate that very accurately, right down to the physics and viscosity of saltwater,\u201d he says. \u201cAs VR improves, the realism and immersion quality are growing by leaps and bounds.\u201d<\/p>\n\n\n\n

The Ethereal prototype requires on-demand, full-force feedback from multiple vectors of the player\u2019s arms and legs to simulate these fitness experiences. In other words, the player might perform a motion that replicates a chest press or a lat pulldown<\/a> to control the robot tank.<\/p>\n\n\n\n

The real-world challenge is that this requires the central carriage to move up and down in a full range of motion with very little resistance. Zero resistance is not possible, but Summit intends to get as close as possible.<\/p>\n\n\n\n

\u201cStrength to weight ratio is critical, especially for the suspended carriage that holds the user interface,\u201d continues Summit. \u201cEvery gram we can remove helps. We want a machine that can handle a 250-pound person hanging on it but be light enough to give the perception of zero mass in free motion.\u201d<\/p>\n\n\n\n

Ethereal is pursuing these goals with generative design under a 2.5-axis manufacturing constraint within Autodesk Fusion 360<\/a>. The main target is the carriage, which is milled from a chunk of 6″ x 6″ box tubing and includes critical suspension points where bearings meet the frame and rail. <\/p>\n\n\n\n

Optimizing for low weight and high strength, Fusion 360 produced a triangular lattice structure close to what Summit had originally imagined. \u201cIt was validating to see what the generative design engine came up with,\u201d he says. \u201cWe knew intuitively what it should look like, but we didn\u2019t know how thick the beams should be. My initial calculations were significantly different from the generatively designed<\/a> model, so that\u2019s exciting. I\u2019m ecstatic with the initial result.\u201d<\/p>\n\n\n\n

While the Ethereal prototype is still in progress, Summit remains confident the generatively designed carriage will preserve the desired structure while reducing total mass. Additionally, the 2.5-axis constraint ensures efficient manufacturing.<\/p>\n\n\n\n

\u201cThe 2.5-axis constraint ensures that we\u2019ll be able to manufacture our product using standard plate and billets,\u201d says Summit. \u201cThat\u2019s vital. To 3D print one of our components would cost many thousands of dollars, but now we can hog out material from about $100 worth of box tubing.\u201d<\/p>\n\n\n\n
