the best way is of course to disassemble the vehicle and rebuild it in the orientation you want it to go
-
At a certain point, it’s just the vehicle’s size that matters and not its turning angle.
-
If anyone is curious, quite a few actual production cars did successfully implement 4 wheel steering in their vehicles, Nissans HICAS system comes to mind but there's a few more
-
For those who don’t know, differential steering is how most heavy equipment such as skid loaders, excavators, dozers, etc steer.
-
We need to see one with Ackerman geometry
-
Dude one-ups himself with every camera cut. Love the creativity
-
The differential one before the trailer's my favourite, I like how it turns without the wheels turning left or right
-
It would be interesting to also include the effect of wheelbase on the turning circle, and show how a compact car can turn much better than a large truck or SUV, and how even long buses can achieve reasonable turning circles with large rear overhangs.
-
I think the 4 wheel steering one would have been better with a central differential. It sounded distinctly unhappy and that's the first thing that I can think of that might have caused that.
-
I love how as the videos go on, the ideas just get more and more insane!
-
It’s weird this channel is part Lego for fun and half way between a science and education and partly asmr, I love it
-
You know what, all vehicles should be able to fold up like that. Imagine how much less space we'd need for parking! xD
-
I will never get bored of these videos
-
I’m more suprised by how perfect of a circle those drive lines are , good job bro
-
"Babe, why are you taking notes?"
-
Your videos are so educational. I love them so much, please try to make two videos per month not just one ❤
-
I love these so much, short and very interesting to watch :)
-
Superb explanation! Thanks
-
You are the best at Lego experiments. Please do not stop doing these videos.

One that's slightly more useful (and insane) than the transforming vehicle: One that's programmed to do a wheelie and balance on its two rear wheels like a hoverboard as it turns around. :P
