Hi all I was struggling with this build for a while, mostly on the software part. But here it is. Buggy is carrying Ev3 brick and Android phone paired via Bluetooth. Phone is sending video feed from camera to another device via WiFi and receives motor control commands from it. This second device can be Android or PC. In theory this would allow exploring surroundings without eye contact with vehicle but in practice navigating is hard due to lack of ability to tun in place. Next version will have tank drive instead. In the end I'm still happy with the results, I've made several attempts on the video streaming software and in the end done it from scratch by sending raw data via UDP packets. Video stream is pretty lagged on the presentation but it depends on the streaming device performance, used one is from 2012 and pretty obsolete. I get almost real time stream when using my other phone (used to film this). I've done it in Unity game engine and whole project is available on github: https://github.com/laggyluk/LegoExplorer

yeah, with $$$

Actually there's a "crane" in this design that was supposed to lift the track with obstacles a bit now and then. In the end I didn't connect it because collision detection was already dodgy

Could be done but with a lot more money.. didn't even had enough bricks to build background or chassis

Hi I've built sort of an arcade game. Controlled with single button, much like famous Flappy Bird. Enjoy ;)

tou can put a roller with 'soft' spring suspension there to give it some more tension

I guess ev3 color sensors could be used in light strength measurement mode for binary protocol, dunno if nxt sensor can do that though ok nevermind then

Feeder was the hard part, first version was bigger and totally different but jammed even more. Skittles are sticky and size doesn't really fit lego 'units' so it's problematic. Feeder version two jams a bit less but has space for maybe 8 pills at a time. Color detection also isn't that great. It often gives false result, perhaps because pills are round and glossy. In that case it will go to 'mixed' cup.

I used 1234D Catch from Autodesk http://www.123dapp.com/catch it's buggy but when it works results are not bad Nice laser scanner btw

Well, sort of. What it does it rotates around the subject-object taking photos for later processing in photogrammetry application. video: and not-so-fine resulting model:

Hello everyone, it's my first post here :) I wanted to show mindstorms robot I've build a while ago: skittle sorter. As name suggests it can sort skittles by color, very useful! video:
