Hi! This is my first post as a contributor of the NXT STEP blog.
I have had Mindstorms sets for about one and a half years now. My first was a RIS 2.0 kit. I liked Mindstorms so much that I bought another second handed RIS1.5 kit. And in January this year, I couldn’t resist buying the NXT set…
The robots I have built with these kits can be found here. Also, together with the people from the official Lego message boards, I launched a website featuring building instructions for NXT robots.
As some of you may have noticed, I am fascinated by LEGO brick sorting robots. I have built three of them so far. As you are reading this, number four is under construction…
The first and second used the RCX, the third was made of the NXT kit. The fourth will use both NXT and RCX.
This machine should sort 10 kinds of bricks. (5 colours and 2 sizes) To ‘see colour’, it uses a photocell and the LEGO lamp. This way the NXT is able to see the difference between black, gray, white, red, yellow, green and blue. This is impossible for the NXT light sensor.
When the folder is public, you can find some pictures via my Brickshelf.
I hope to provide some useful posts to this blog!
