In an earlier article I wrote, I tested how fast I could push the HiTechnic ProtoBoard and the MAX127 ADC under ROBOTC.  In a recent discussion with Deepak from Mindsensors, I2C speeds in ROBOTC on the NXT came up.  The questions arose about the most efficient read size for the NXT and if there was a ceiling or a cut-off ...

A new version (1.1) of the ROBOTC driver suite awaits your download from the usual source. Not as many changes in this release as with the previous one. Changes include: Added support for the Mindsensors Servo controller, up to 8 servos per controller. Added a new function to get the raw uncalibrated AD values from the sensors in the Mindsensors ...

After a long time between releases, I am proud to present to you the latest version of the ROBOTC Driver Suite. The biggest new addition to this version is support for the new HiTechnic SMUX sensor. Adding support for this new sensor involved modifying almost every single driver for the HiTechnic sensors to add the ability to poll the sensors ...

Be sure to let your grand parents know about this. Thanks.

I’ve had my ArduinoMega for almost 2 weeks now and until today I had no luck getting it to work as an I2C slave with the NXT.  The NXT is a finicky beast when it comes to I2C.  It’s really not all that standard and requires very high pull-ups (82K) for the NXT to be able to pull the lines ...

Another release with some changes and additions: HTAC-driver.h: Fixed bad registers Added HTACreadAllAxes(tSensors link, int &x, int &y, int &z) Removed HTACreadAllAxes(tSensors link, tIntArray &data) Changed HTACreadX, Y, Z to use by reference instead of as return value HTIRS-driver.h: Fixed wrong registers HTEOPD-driver.h: Added HTEOPDsetShortRangeNW and HTEOPDsetLongRangeNW, these don’t wait 10ms Changed the underlying sensor types for ROBOTC 1.57A and ...

A new version of the colour sensor has been brought out by HiTechnic.  It features a number of new abilities: Increased sensitivity; the sensor can determine a large object’s colour from up to 20 cm away. No longer needs an RGB LED but uses a bright white LED instead.  The RGB values are determined by the very sensitive colour sensor. ...

Having read the countless articles, websites and hearing about it from friends, I’ve decided to jump on the Arduino bandwagon.  I bought one of the new ArduinoMega boards with a very nice shield and some other things.    The ArduinoMega is an Arduino compatible board with an ATmega1280 controller that has 128KB flash, 8KB SRAM and 4KB EEPROM.  It has ...

I love our dogs more than anything.  Even more than my NXTs.  I can hear you all gasp and mutter “blasphemer!”.  Now before you throw me on the fire, you must understand that I was a dog person before I was a robot person. Anyway, as I was saying, as much as I love my dogs, they have a tendency ...

Did you just buy a Wii-mote for a robotics project and you can’t wait to use it?  If you have a 15-tonne hydraulic grappling arm at your disposal, you could do what these guys did. I am sure this beats the crap out of whatever you had in mind of controlling with that Wii-mote.  Feeling inadequate yet? [Source: Entity Crisis ...
