Actually I don't want to make the speed builds too fast so that nobody can see the pieces as a result... ;-)
I've got a new video on YouTube about a train ride in my modular town layout, Navatown:
Here is the YouTube description:
00:00 - Genesis of the idea
14:49 - Demo of construction site
23:12 - Wrap-up
25:19 - Bloopers
In this video, I show how I created an automated construction site using Lego Technic. The Lego Technic Sets I used were the 42030 (Volvo 350F Loader/Volvo A25F Dump Truck) and the 42100 (Liebherr 9800 Excavator). The solution also includes an SBrick Bluetooth controller for the 42030 set along with a Pixycam by Charmed Labs paired with an Arduino board.
The first part of the video shows the genesis of the project. That is followed the Liebherr scooping up ping pong balls and dropping them into the A25F without any human interaction. I then wrap it up with some commentary on future things to do and send you off with a bunch of bloopers.
I used Visual Studio and C# to create a UWP program for Windows 10 that communicates via Bluetooth to the Pixycam (via Arduino) as well as to the SBrick and the new Lego Control+ Bluetooth Hub for the Liebherr 9800. The VisualMicro extension for Visual Studio was used to program the Arduino. Color codes were placed on top of each Lego Robot and "Ball Depot" allowing the Pixycam to detect their position and orientation.
I will be posting the Visual Studio code up on GitHub once I clean up some of the UI and add more comments to the code. I will be coming out with more detailed videos on this project including my experience with the Pixycam, Arduino programming and how it all came together in a UWP C# program in Visual Studio .
