Self Guided LEGO Vehicles


Hey everyone. Jason here.
A few weeks ago my local LUG set up a LEGO display at the Ottawa Train Expo, and I was challenged by one of the other members to build a self-guided LEGO vehicle to drive through the layout, and today I’m going to show you what I did. It’s actually extremely simple.
It all comes down to the power of… magnets. First, let’s take a look at the vehicles.
I designed both of these OC Transpo buses around this basic frame, which i think is
about as small as you can get using stock Power Functions components. Here we have a battery box and an M motor With a belt drive to transfer power
to one of the rear wheels. For steering, we basically just have this run of the mill… steering system with the addition of
this bar connected to one of these old 9V
train coupling magnets. So as the vehicle drives on the road plates,
the magnet slides along surface following a wire that is taped underneath. For wire I’m just using some old picture wire I had around the house.
I taped a section of it underneath each of the base plates.
Which you can see here. A curve and a straight.
And this just makes it easy to transport and setup, and configure the loop however you like.
So that’s about all there is to it. If you’re interested in building something
like this yourself I have posted instructions for how to build the frame on the website, along with more detailed
information on how it all works. I hope you enjoyed the video.
Keep on building, and we’ll see you next time.

    i think that you also can use those old train tracks where the middle part ( where usually electricity runs true) also is magnetic. if you use that it's also from lego and you use only lego parts

    Hello, I really like this model JK, so much I'm trying to build one but I'm having trouble with the wire. Can you tell me the name or give me a link to where you bought it. Also can you tell me the strength of LEGO's magnets, thanks!

    You can make the bus stop at stations by adding reciever above the steering system(if the reciever is to high just change the bus into doubledecker to make more room) then just operate remote control via EV3

    Pretty cool, I think someone at my local LUG must have seen this, they have a few self driving bus too. The LTC has talked about having one on a layout, but given how long it takes us to set up as is, we haven't done it yet. Right now I just drive my RC LEGO car around, its an 8-wide though, so doesn't quite fit scale wise.
