MOC: Self Steering Truck

[solta]

As it says in the title, this is a Lego City truck, which turns the front wheels by itself in the direction you push it. I got the inspiration for this creation on an official Lego channel on YouTube with video

.

The vehicle is not exactly a great aesthetic achievement, but at the end it was more to the functionality than the looks.

Here are some pictures:

How it works on Lego City streets? Watch the video:

Here is the explanation:

The entire system is mounted in the lower part of the plate 4 studs wide (not shown in the picture). So the blue half-pins for attacing are mounted in to the middle circles at the bottom of an ordinary Lego plate and this amounts to width of 3 studs.

The gray parts are in this case fixed and do not move. Purple pins connect them into a whole.

The green part is responsible for a steady rotation of the black base for the wheels. Black base are connected with orange axle-pins to the gray and green parts.

Red pins secure the wheels to the black connectors.

Brown pin is added as a limiter for the wheels movement so that they are not rotating too much.

I absolutely love it. Not only it self-steers, but it also looks really good, at least in my opinion. Well done, 'solta'!

AWESOME idea 'solta', great truck with a very clever steering system.......Brick On Truck On 'solta' !

Really interesting build! I really like this idea. And I really love the fact that it fits a trucs that is 6 wide and needs no (or almost no) compromise on the car cabine design! Really well done.

Just one question about the self-steering: do you need to apply pressure on the truck when turning to make the wheels turn?

Great idea and well executed! It would be perfect for extra playability for the kids. And I for one quite like the look of the truck, every city needs trucks

Awesome work and happy building

Yes, excellent designing! It looks like quite a system you designed, it looks to work very well

This is rather novel, I may have to create some myself. Thanks for sharing it.

Looks very nice, well done! Self steering seems to be the vogue ...

The mudguard parts you use are very suitable for that purpose - there's enough room for the turning wheels yet the looks are nice. I must try something with them, too.

Keep it up!

Thanks everyone for your response.

Just one question about the self-steering: do you need to apply pressure on the truck when turning to make the wheels turn?

You apply only a little push to the side. Less than on the official Lego cars, which do not have turning wheels.

I really like to hear this. This leads to the term playability.
