The mailman brought me a cool new toy to play with this afternoon!  It’s the Mindsensors GlideWheel-M!  These are so cool, you can now use the Large XL Power Functions motor with the same degree of accuracy as an NXT motor.  The GlideWheel-M is just a single unit thick and fits very nicely onto the motor.  You can mount it ...

Finally, after months and months of stalling, I have started and completed a tutorial for my Driver Suite. It actually took me a lot less effort than I originally thought it would, but I am happy with the result, as I am sure you will be. The tutorial will help you setup ROBOTC to use the drivers, how the they’re ...

I don’t usually use graphs but when I do… Ever since I started writing my drivers back at the end of 2008, I would not have thought that I would now be almost at 6000 downloads. I was pouring over the stats and I noticed something quite cool.  It is not hard to tell that my main user base are ...

  Dexter Industries seem to really crank ‘em out lately with all the new sensors.  This time they’ve made a really nice compass sensor based on the Honeywell HMC5883L 3-axis digital compass IC. I’ve had the pleasure of playing with this little beauty for a little while now.  A preliminary driver will be part of version 2.5 of my driver ...

Now here’s a bargain you can’t refuse.  The folks over at Robotics Academy have created an RCX-only version of ROBOTC 2.03 and made it available for everyone to download! For free, no less!  That’s a lot of exclamation points! Ever since ROBOTC 2.02+ was released without RCX support, a lot of folks were complaining about the inability to use their ...

Mindsensors have made a new pressure sensor and it’s really sweet.  It uses their new compact sensor housing and it’s very slick and robust looking.  Rather than calling it the PPS v3, they gave it the uebercatchy name PPS58-Nx. So what can it do?  It can measure pressure from 0 to 400 kilopascal (1 to 58 PSI) with a 1 ...

Titus Woo posted on the ROBOTC forums about a really cool new program he’d written to make it easier for FTC teams to make a teleop program for their robot.  I’ve never done FTC but I maintain the ROBOTC forums so I see a lot of question go by during the season about the teleop (Remote Control) part of the ...

I received my HiTechnic SuperPro Prototype Sensor in the post yesterday and it’s epic.  It’s epic for a number of reasons: It has more inputs and outputs than you can shake a stick at, both analogue and digital. It can 6 digital strobe outputs (great if you want to start your own disco or see which of your friends has ...

Ivan Seidel from Brazil made a really great video to explain how PID control works. The video is in Portuguese but if you click on the “CC” (closed caption) button at the bottom, you’ll get English subtitles!  Go watch it, it’s really awesome.

Dexter Industries have used their WiFi sensor to send a Tweet straight from the NXT over WiFi! It uses the Arduino Tweet Library relaying site to send them which is really, really cool!  I am so going to rebuild TwitterTattle to do this.  No more tethering needed! This is fantastic. The code for this will be available very shortly, it’s ...
