‘CableRobot’: A Crazy Motion Platform for Complete VR Immersion, If it Doesn’t Kill You


Now that some of the hardware problems surrounding virtual reality, such as 1:1 head tracking and high frame-rate displays, are being resolved, the ways in which a player’s physiology can be brought in line with the mind are being looked to as the next step for complete immersion. This latest contraption aiming to do just that is called CableRobot Simulator and it’s one of the most unique motion platforms we’ve yet seen.

Update: Seems I found wrong Cable Robot in our original story. Below is updated with new information about the project.

CableRobot Simulator is a collaboration between the research group of Heinrich
Bülthoff at the Max Planck Institute for Biological Cybernetics and the
cable robot research group at the Fraunhofer IPA.

The CableRobot Simulator is comprised of a central ‘cockpit’ frame, complete with chair, harness, modified Oculus Rift DK2 and computer to power it. The central cockpit is attached to a series of motorised winches which are coordinated to apply or release tension to and from the cockpit in such a way as to allow elevation, descent and rotation of the platform – giving a full six degrees of freedom for movement (6DoF). The system is said to only be limited in terms of scale, by the room it occupies – although I’m fairly sure physics would step in to spoil the party at some scale.


What the system offers that many fixed-base motion platforms down is a large degree of movement in the forwards / backwards, left / right lateral movements. The unit on display occupies a small warehouse, which means large swooping motions can be actioned upon the player seemingly with ease, making the job of fooling that clever physiology of your all the easier.

The system seems to employ a proprietary optical tracking system, to grab the position of the user’s head via an HMD mounted three-point system (above). A developer on the project Joachim Tesch, told us that “We’re currently using a DK2 as the initial visualization solution but might also use projection or other large-screen solutions in the future.
Better HMDs of course as well,”. And on the subject of that tracking solution “Since the Oculus DK2 tracking system was not designed to work on a motion simulator we are using an external optical tracking system. This is still work-in-progress and needs further improvement to match the quality of the Oculus tracking solution.”

The team have produced simulators specifically to work with the motion platform too “Graphics for flight and driving visuals are done in Unreal Engine 4. We modified it to work with the optical tracking system and also to connect it to our simulation environment.”

It has to be said, considering the debate that room-scale VR has brought about in terms of available space in homes, it seems unlikely many of us will be rushing out to procure such a device any time soon. And given the frankly lethal looking nature of the machine’s mechanics, we’re not sure if you’re likely to see it at a theme park any time soon either. There’s no doubt though that we’d absolutely love to give it a go!
