I am currently streaming a live feed of my NXT on UStream. You can easily control the motor on my NXT using URLs like: http://xammy.demon.nl:81/MOTA=0 – stop the motor http://xammy.demon.nl:81/MOTA=100 – run the motor at 100% clockwise http://xammy.demon.nl:81/MOTA=-50 – run the motor at 50% counter-clockwise. The power to the motor [...]
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 [...]
As promised,here’s an easy to follow HOWTO for making your own VEX Cortex to NXT converter cable for I2C sensors. Please keep in mind a few things: Do this at your own risk This won’t work with sensors that require 9V to operate This won’t work with analogue sensors Do [...]
So I’ve had these Dexter Industries NXTBees for about two weeks now and I’ve been working hard to come up with something cool. Even before I received these NXTBees I spoke with John from DI about sending telemetry data from one NXT to another over a distance using these sensors. [...]
Literally. The omniwheel is capable of going in any direction you want, it can also rotate on the spot. So I thought, why not combine the two and make it rotate and move? After picking Brian Davis’ sizable brain about using a gyro as a means to calculate a heading, [...]
If you’re like me and are the proud owner of a small room, also known as the Lego Lair, you may find that the lighting conditions in said room sometimes leave a lot to be desired. You may not really notice this until you start using a sensor that uses [...]
Programming the NXT is nice. However, sometimes you run into limits that you think shouldn’t be there. This morning I hit one of those and scratched my head: “How to fix this?”. Normally there are 4 timers at your disposal in ROBOTC (this also goes for NXC, as far as [...]
Meet BobBot Mk2, the intellectually challenged robot. This subsumption based robot is probably the most challenging robot I’ve ever had to program. It has quite a number of sensors: Mindsensors NXTCamV3 Mindsensors Magic Wand Mindsensors Dist-nx HiTechnic Sensor MUX HiTechnic EOPD LEGO Touch Sensor x 2 LEGO US Sensor Subsumption [...]
For the longest time I’ve been meaning to do something with the RAMTRON FM24V10 chips that I got as a sample some time last year. They’re I2C EEPROM drop-in replacements, meaning they are functionally and electrically identical to the standard ones we see everywhere. Their main advantage over standard I2C [...]
I’ve been meaning to build something cool with the NXTCamV3 for a while now but never got around to it. I tried making the Omniwheel suitable for the NXTCam but unfortunately the wheels cause way too much vibration when the robot moves. Oh well, in the not so distant future [...]
