Our Flickr page has been updated with some new photo’s of the Delivery Station for Lego World 2016. You can click on the picture below to view the photo’s or click here.
All years, we use a color selector device (we call it the PUI, the Physical User Interface) as the starting point of our track. Over the past years, the PUI looked like this:
In the previous article, I explained about the new Delivery Station for Lego World 2016. In this article, I will give an update about the progress.
For Lego World 2016, we are engineering a new delivery station. Some background information: in the 2015 version, the candy crane grabbed the candy directly. Unfortunately, too often the candy fell out of the grabber during the movement of the crane. Therefore, we decided to update the crane that it would pick up the complete container (with the candy, of course :-)). The crane update is already finished as you can read in our previous article. In this article, you can read about the ideas of the new delivery station.
A new video has been uploaded to our Youtube channel about the candy crane version 2016:
- Improved grabber
- More robust look

At Lego World, because of the power consumption, it was needed that we hooked up both EV’3 to a power transformer. The cables of the transformer sometimes got into the running wheels, causing the system to fail. So, we needed to add a power chain system like this:
