The most common I've seen is rack and pinion: Essentially you have two parallel beams with one fixed to the car's chassis. The other bar moves horizontally which changes the direction of the wheels. Attach some gears and you can hook it up to a steering wheel. The steering technique has been used in the Whirl N' Wheel Super Truck (5590) set. The ...

This can be done without a caster wheel as well: Start out with a three wheeled vehicle, with two wheels in the front and one smaller wheel with less traction than the front wheels in the back. All wheels need to be fixed. One of the front wheels is attached to the motor. This might need to have some gearing to get an appropriate speed. The other front ...

That would be 781 Vehicle, Base 6 x 12. It only came in 3 sets from 1972-1975, with only 379-2 Car and Caravan having it in white.

That's one of the alternate models for Ocean Explorer (31045): The instructions are available on LEGO.com.

Ever since this question was asked I wanted to build something that would fit that scale. Here's the result: I know this is not using only LEGO pieces but, I thought that there was no way to make the LEGO motors fit 'inside' a normal looking LEGO City vehicle. So, this is basically a homemade motorized brick made of a 2x2 brick glued to the 2x2 wheels-...

This set is 6848 Strategic Pursuer. Instruction scans are available on Peeron.

I would suggest looking at a speed build of this model and comparing the placement of pieces with that of your own. So, let's try...this guy's video => The Austrian Lego Fan seems to have banged out a step by step build of this model, which shows a many angles of the area you're have issues with. To get those butt-dragging results, you may have got your ...

This is set 8425 (quite a nice set imho) and the instructions are downloadable from lego themselves: https://www.lego.com/biassets/bi/4101173.pdf The set is from 1996

Assuming that you're asking about the engine in particular, it seems to be a large number of pneumatic engines that have been coupled together in order to supply the required torque. LEGO pneumatic engines typically consist of a pneumatic cylinder driving a crankshaft. Here's a basic picture to give you an idea: The shaft usually also controls a pneumatic ...

In WeDo 2.0 app "LEGO® Education WeDo 2.0" there is a complete project 12. Steer that is exactly about that When it drives forward it goes in straight line, when it drives backward it then turns to one side. There is full build instruction in the app. I've also added distance sensor and made it fully autonomous - whenever it sees obstacle it goes back, ...

It looks like a pretty generic twin engin-ed WWII bomber. Maybe like this Mosquito bomber?

Gev already answered the question about availability. LEGO Ideas sets are produced in small quantities. Perhaps this will change in the future as LEGO Ideas is now out of beta testing and was brought in-house by LEGO. The Curiosity is not going to be back unfortunately. I just called LEGO about this a couple of days ago. As far as the Curiosity inventory, ...

Obviously The Lego Group has not released any sets specifically designed for the constraction figures, but some sets would still be reasonably sized. I've never asked a storm trooper, but let's assume he is 6 feet tall, or 72 inches. According to Brickset's information, 75114 is "over 9 inches tall" That makes the scale for the figure about 1:8. Now ...

From a glance it doesn't look like a set as much as something someone might have randomly put together. The two blue 1x2 tiles at the front seem odd, as do the double-stacked black round tiles. Of all the pieces used it seems the rarest would be the blue steering wheel or the blue seat. It turns out the blue seat piece is used in 'only' 67 different sets. ...

As far as I know, there isn't an ambulance slated for release in 2017, and there hasn't been one available since 4431 in 2012: This set can be picked up currently for as little as $30 used on Bricklink or eBay.

I designed some WeDo 2.0 models that can drive and steer using just one motor. This one uses a system of gears to alternately drive the left or right wheel of a differential drive robot, depending on the turning direction of the motor. You can find the complete building and programming instructions here: https://robotics.benedettelli.com/lego-wedo2-zigzag/ ...

I don't recall an official statement, but one story I read said that they made a deal with the original designer to limit production to one run, but that seems almost apocryphal. As for buying the pieces you need, I would think you'd have better luck on Bricklink. It's possible that the PaB on S@H might have all the pieces necessary, but that seems truly ...

Assaf, please note that this is not part of LEGO's website. StackExchange doesn't sell LEGO sets. In regards to your question, you are right; the #10187 LEGO Volkswagen Beetle is no longer available directly from LEGO. It was a set that was released back in 2008. LEGO usually keeps sets on the market for a couple of years, sometimes a bit longer if they are ...

These blocks appear to match your description, would this be the type of brick you are talking about?
