In the future, I'm planning to do all I/O via Bluetooth. I was wondering if it is safe to operate the Intellibrain 2 without the LCD, the idea being saving...
Joe, Yes, you can safely operate IntelliBrain controllers without an LCD display. See the following for a Bluetooth adapter we have tested. Regards, RidgeSoft...
I'm getting compile errors on a couple of my classes and I'm betting that I am using things that are not implemented in the VM. In general, can I assume that...
The entire system works great. I am very pleased. I'm using NetBeans to compile and include the resulting JAR file in the project properties. It works fine...
Hi Joe, Make sure only RoboJDE.jar is in the class path of your compiler. It sounds like the compiler might be picking up the Integer class from a source...
Any suggested starting values for the gain and itermmax settings? I did not see anything in the examples. Also, what would be a reason I would NOT want to do...
Joe, The gain constants and integral term maximum are totally dependent on the characteristics of the system you are controlling. The following document gives...
Hi all I am having trouble getting my new Intellibrain2Bot to do the Line Following trick - it does not seem to drive the motors at all - I have tried other...
Hi Garth, The sensors should read very high over black - 600 to 900. It could be the surface you are using is not opaque or is too reflective, which would...
Can anyone tell me .... I teach AP COmputer Science and am using JAVA 1.5 with JCreator 3.5. Can I write my programs in JCreator using "standard" java along...
Phil, You should be able to use JCreator to edit and compile and RoboJDE to download and monitor your programs. Although we have not tried this with JCreator,...
My apologies if this has been posted before, I did my best to search. Anyway, I am having trouble controlling the speed of the servos. According to some of the...
How do you change the default project directory? My software seems insistent on saving back to the original directory when the software was installed....
RoboJDE saves the path to the current project in RoboJDE.ini (\Program Files\RoboJDE\RoboJDE.ini) when it exits. When you restart RoboJDE it will open the...
Yes, you can use the IntelliBrain-Bot with a Bluetooth wireless adapter attached to either or both of the serial ports. We have had good results with products...
You could always tack on one of these and control it with a UART: http://www.sparkfun.com/commerce/product_info.php?products_id=713 -- Don French ... From:...
Hi Don, The printChar routine enables the calling thread to attempt to print a character to the LCD screen without waiting if the LCD hardware is busy. If the...
Ah! There it was, right in the Javadoc. I guess I missed it because all the other LCD display classes I am familiar with do that kind of readiness-checking...
Oops, it is not going to be that easy to subclass Display. The problem is that you can't subclass Display without implementing printChar( ) because for some...
Hi everyone. i keep getting these semantic errors and i have tried to fix them in vain can anyone tell me what is wrong. Found 1 semantic error compiling...
I downloaded a program to flash for the first time and now I can't download a new version of the program! RoboJDE never sees the Intellibrain (Load is grayed...
Don, Try the following: 1. Turn the robot off and disconnect the serial cable. 2. Close and restart RoboJDE. 3. Adjust the baud rate of the robot to match the...
You must have missed a step because after step 4, the robot is off and never turned back on before step 8 when you say to turn it off. And the Load button...
Don, I just loaded a board with a program that grabs COM1 and was set to automatically run. The previous test I tried was without the COM1 twist. I am able...
Sorry, this does not work for me. Let me step you through exactly what happens. After step 6a, I do see the message: RoboJDE v1.2.2r1 Ready - Flash and the...
