STEP <b>NXT</b> - <b>LEGO</b> ® <b>MINDSTORMS</b> ® <b>NXT</b> Blog: distance <b>LEGO</b> <b>...</b>

Blogs, forums, and file sharing have changed the face of how we interact... but I guess that should say that anyone reading a blog, right? About a month ago, I was contacted by a NXTasy (may he rest in peace) user, David Bell, on the development of a robot that could produce a graphical display measurements of CO2 for a public display of 4-H bar style. He even offered deliver me all LEGO parts, sensors, everything you need and pay for the materials I need to purchase. Even for me compensate my time.I occupy him on it.
The reason was not that I was in a mood of average, or I'm independently rich (feel free to throw these tens and twenties people this way!). It co my worms I this pleasure and if I can help other people in the process, so the better... and if we can all be dirt cheap, fantastic! So instead of shipping it for me and me by producing a "product", we decided to collaborate on long distance. The goal was to produce a robot that could attract a series of physical lines on a large screen and for which he built NXT-based & working by 2 October 2010 for national youth science day in the Park of walnut, David Petaluma, CA. would the HW, and he worked long term with Vernier people to interface their CO2 detector (requiring too mu ch you can work directly off a sensor port) with the NXT. Meanwhile, David & I discussed (ignored) different plans for the robot and I created a very simple which could drive around and draw lines on a sheet of melamine. I it documented with photos and then sent him the picture so that it could create a copy, even though I wrote a test for the sensor program (which I had never seen or used). Once again, we have the sensor works, written a program for the robot to draw lines, while David tested responses of sensors to establish how well it worked and its limitations, give me feedback in the form of pictures and videos. This round a design process and ' tour several iterations, with me sending detailed commented to him and him build a table so that it runs on programs and test before other suggestion end result me.The revisions is TurtleBot: robot kit plane simple retail base, which can accept most of pens and draw on any surface (paper, Melamine foil, etc.) and draw a bar chart of CO2 readings when requested by a user (or on its own), itself on a long wall right repositioning. The first public test was last weekend, come this weekend and will be on display (and sampling to your source of CO2 favorite) 15 h on the national day of the jeunes.Si science you are out of the Petaluma, CA area, please stop and see (as well as many other incredible interactive science views). Robot is a kind of cute and works really well for what it is (and is built with SDK 2.0 release only)... but there are certainly better Turtle-style robots there (Marty, since the book idea for example 1.0). But in my opinion, the real cool here is not in the way it came about.Remember robot.It If you get to see, it is a robot that was developed in cooperation, without having any of the principles to be able to set and without delivery all materials around physically... because we were able to prototype with a simple, readily available modular construction system (LEGO), using a very easy programming (NXT - G) language and the ability to network with people literally on a continent.The robot is clever. The concept of an interactive display was fantastic. But the ability to lift everything with a geographically challenged "group" in a few weeks due to the internet and the simple, easily accessible, the modularity of LEGO... that is really, unpublished, amazing.Go see David Bell, and the two rock 4-H Club this weekend at the national day of youth at the science park of walnut, Petaluma, CA. And the wave to TurtleBot for me.I manquer.Il never sends me.Labels: community, sensors
