BobBot Mk2 has learned a new trick: finding a can.  Finding cans makes BobBot very happy; he even chirps when he sees one and gets very loud when it’s about 10 cms away from one.  A lot of work still needs to be done: Approach towards can needs to be PID controlled for smooth steering instead of the waggle it ...

It’s been a bit quiet here.  Mind you, this isn’t because I’ve been slacking.  Far from it, in fact.  I’ve been working on a new version of the driver suite with a number of new drivers and some other assorted goodies.  Some new devices that will be supported by the next version are: Mindsensors Motor MUX (no product page yet) ...

Mindsensors are very busy working on their latest sensor, the Motor Multiplexer, also known as the NXTMMX. This compact MUX can control up to two motors and allows you to daisy chain up to 5 of these.  All of the bugs have been ironed out and I’m grateful to Mindsensors for having implemented some of my requested features.  The first ...

No big announcement from the LEGO side, but it seems that the source code for the 1.29 firmware is now available at the LEGO website.  You can download it right here: [LINK].  As per usual, the naming standard of LEGO’s downloadable files will make identifying the file super easy. In order to compile this, you will need a copy of ...

The state of my desk pretty much represents what I am currently working on: In the middle is the Holit Data Systems motor-MUX.  That’s the big sensor with the 5 ports and the bright LEDs on it.  I am writing a ROBOTC driver for it. Just below that is the HiTechnic sensor-MUX, I’ve written an NXC driver for it that ...

I don’t usually write about non-NXT related robots and I am not even sure if this really is a robot in the strict sense of the word.  However, when I ran into it on this website here: [LINK], I simply had to share it with you.  Prepare for a serious dose of “WTF?”.     There are more pictures in ...

I love days when I really feel like building something, you know that inspired feeling you get?  Today I started building at about 9am and didn’t come out of my Lego room all day except for dinner and lunch. I took some pictures of the unholy mess my desk was covered with. The first picture was taken after about an ...

This weekend I went over to my friend Martijn to hang out, play with Lego and fiddle with electronics. He’s been working on a top secret project of his and we experimented with a couple of options to try and get it working.  So far, so bad, though, so I guess there’s still work to be done.  The top secret ...

My friend Ramacco finally completed his NXTfied Red Crane Truck.  After months of building, tearing it apart again and rebuilding, he’s finally done it. The end result really is amazing.  A job well done!
