Adrian Akau April 9, 2021 09:06 AM I am sure that there will be good use of this concept in the future. I have often thought about designing a car that could change its body shape just a tad according to its speed to reduce air resistance. ppeter April 9, 2021 09:08 AM Another great solution in desperate need for a problem it could solve? CraigAllenCorson April 9, 2021 09:48 AM This product will go NOWHERE in the passenger vehicle market. It's fine for robots, but that ride is WAY too bumpy for human beings. 1stClassOPP April 9, 2021 11:25 AM I love it! Imagine the ratio difference in torque and speed, and obstacle clearance. Think variable ratio transmission. Great! ARF! April 9, 2021 12:50 PM I'm no mathstrologist. I'll just keep wondering if wide tires cancel out ground-hugging aerodynamitry. AngryPenguin April 9, 2021 10:21 PM Looks like it would be useful as a 'folding' wheel. SpieroFantasio April 10, 2021 09:17 AM Probably it is made to replace the gearbox similiar to a CVT. knelipot April 10, 2021 12:33 PM Mud boggers are gonna love these. When the mud pit gets rutted with tall, narrow tracks, just widen the tires and straddle the ruts. Justin Clark April 10, 2021 03:43 PM It's funny that it took researchers and scientists to come up with this idea that is just like a toy I had called the flex from the 1980s did the same thing thank you scientists Worzel April 11, 2021 05:04 AM The weak point is the 'hinge' and that is in exactly the position that will receive the most wear and tear in off road use. When the hinges start to break....!I've a mini-digger, that has rubber tracks, and the failure point of those, is the steel cross pins that the drive wheel engages, which get ripped out of the rubber. So the weak point is the bonding into the rubber. These wheels will probably have similar fail problems. If I can see these problems, then potential buyers will also, and will want some very convincing answers.
