Picture of R/C LEGO® Car Redux
After I built R/C Lego Car, that used hacked motors and motor housings from the toy Car and toy R/C cars. I realized most of the parts from that toy R/C car that I took the motor out of became wasted.
This way was not very practical or not so "green" at all.

So I decided to design a 3D printed motor housing (See details in Step1) that is generic to all of my Lego car designs (details in Step 1). 

This instructable, R/C Lego Car Redux, shows you how to use the 3D printed motor housing with my very first built R/C Lego Car.
Most of the parts from my original R/C Lego Car were still in used in this version. There were also some new Lego parts added, but only a few. 

Eventhough this instructable is a "Redux" of the R/C Lego Car, I am going to show you how to build this car step by step from scratch, just like we tear the model apart and rebuild it again.

One good thing, neither the programming the Arduino, nor the UI to control the car in Processing needed to be changed.

Note: See more photos of "Redux" version of R/C Lego Car and video in Step 12.

I like it! Have you thought about entering this into the LEGO Contest?
sath02 (author)  mikeasaurus2 years ago
I could try. And thanks for the suggestion.

No It won't get in, because it was posted before the start date of the LEGO Contest.
Rats, I misread the dates. Good luck in the other contests!

This is pretty cool, building an Rc Car using Lego, The LEGO set 31006 is a nice on its own, but it also contains some useful parts. Many builders have used these to create another car/vehicle/thing, and this one impressed us the most.
That's cool! you should check out mine. it is completly lego and uses power functions. it is a work in progress. The name is LEGO Fire Falcon with suspension.

Thanks, I'll look at your Fire Falcon!

First time I see the arduino with the lego ;) great design!
You could use a blue-tooth transceiver instead of an XBee as its a lot cheaper and kind of easier to use :D

I will keep the bluetooth in mind. May be I will incorporate bluetooth into my next LEGO car! ;)
I'll be waiting for it ;)

nice build up I like this idea. can you share some link where from I can buy one like this. I am interested in buying one like this.

This LEGO car is a custom design and custom built. You could gather the LEGO components as shown in Step 2 and then build it yourself. You can get LEGO components from various places like eBay (search with key word Lego Technic, Lego), LEGO's shop (http://shop.lego.com/en-US/Pick-A-Brick-ByTheme), or BrickLink.com (https://www.bricklink.com).
For the motor housing, It's still under development. If you have your own 3D printer you can download the file and print it.
I'm still using this Lego car to test a lot of things. So I could not sell it to you right now. Sorry.
