The Infinadeck Omnidirectional Treadmill - Smarter Every Day

ChaosEngine says...

Yeah, that was my thought too. Trackballs also solve the inertia problem too.

There's also a company called Virtuix, that solve the problem by having a bowl-like base with special slippery shoes. http://www.virtuix.com/

Very cool.

I sure would have thought that it would be a platform with hundreds of partially inset mouse/trackballs, rather than treadmills on axes 90 degrees apart. I mean ... sure, any 2D vector can be split into a sum of two orthogonal components. But with redundant inset trackballs you could get stuff like spot pivots that are much finer scale than the scale of the 2-3 inch wide secondary axis treads...

On the other hand, these guys actually have a working prototype, so they clearly thought things through and decided that the orthogonal treadmill solution was better. Rubber meats road trumps off-the-cuff theoretical any day!

Marble Machine - Triple Gears Lift

Payback says...

I think I figured out what went wrong, it's supposed to be "marble", not "bowling ball" wood machine.

Very nice. I had exactly the same design idea, but the modules in my marble wood machine were too heavy to lift.

Still pretty awful, but they don't have complete impunity. From another CNN piece :

<quote>Between 2005 and April 2017, 80 officers have been arrested on murder or manslaughter charges for on-duty shootings. During that 12-year span, 35% were convicted, while the rest were pending or not convicted, according to work by Philip Stinson, an associate professor of criminal justice at Bowling Green State University in Ohio.</quote>
