NXT

Sometimes you win…sometimes you get omni-humped.

Omnihump

I was working on an omniwheeled robot last night, trying some code that would ensure the vehicle would go straight even if the motors were not perfectly in sync.  Unfortunately, there seemed to be a bit of a bug in the code which lead to some pretty erratic behaviour. So as you can see, not all of my projects are ... Read More »

After a prolonged hibernation period, the Mindsqualls project is back from the dead and version 2.0 has been released. I was using an older version in my super secret Kinect project, so it is nice to see that is being maintained again. Mindsqualls is one of the easiest to use .Net library for controlling your NXT using C# or VB.Net. ... Read More »

It measures the pressure in 1/1000th of an inch of Mercury, which can easily be converted other units like Pascal and PSI. The temperature is measured in 1/10th degrees ... Read More »

NXShield for Arduino This shield is designed to fit on an Arduino. It will have 4 NXT motor ports, 4 NXT sensor ports and several RC servo motor ports.

Improved Thermal Imaging

image.png

After the initial post about my thermal imaging system using the Dexter Industries Thermal Infrared Sensor, I made some improvements with both the speed and accuracy of the whole thing. I made the sensor sampling interval time based, rather than encoder value based.  This proved to be a lot better at getting consistent sampling rates.  I also doubled the horizontal ... Read More »

Controlling your NXT with the Kinect

After seeing the video posted on Mauro Brunato’s website, I got all sorts of ideas in my head for other cool things to do with it. With a little help from my friend SC, I managed to get my hands on one of these Kinect sensors as well. It wasn’t easy to get it working, though but with the help ... Read More »
