Bot Bench I'd Rather Be Building Robots
As Martijn already reported on The NXT Step, the FLL Benelux finals were held in Arnhem, the Netherlands last Saturday. Laurens, Martijn and I were there to demo Lego Mindstorms.
Laurens had built a very cool segway robot that could be remote controlled. I had built the new Wall Following robot from the HiTechnic website. It uses the HT EOPD and Lego Ultrasonic sensors to keep the same distance to the wall at all times. It’s a great little robot based on a really easy to build but versatile base, all designed by Gus Jansson. The thing I liked most about this model that during the 7 hours I had it running at the show, it never once strayed from the wall.
I took some pictures of the stands that a couple of the FLL teams had. Some were very colourful and elaborate, others were much simpler. It looked like most of the kids had a lot of fun, though.
Congratulations to all the winners. I can’t wait for next year’s competitions!
Hi, Xander
I like your wall follower robot very much . I have a project for my engineering class and it has to be maze solver. My robot has one sonic sensor looking forward, one color sensor searching on the floor for a black point, and three motors. The maze is on a white surface and there is actually only one black point where the finish is, and it has to drop a ball on the black surface. I’m allowed to use two touch sensors.
Can you help me make the code, please?

I probably could but then you’d learn nothing. I would suggest you start with trying to solve this yourself and when you get stuck, either head on over to the ROBOTC forums, if you’re using ROBOTC or if you’re using NXC or NXT-G, check out the Mindboards forums.
