We are using a different configuration for on/off switches: the switch is between the signal and +5V, and there is a pull-down resistor between the signal and...
Carlos, The way you have connected the switches is reasonable provided you are drawing the +5V from the IntelliBrain board. The microcontroller chip can be...
Robofest is an annual autonomous robotics competition for students grades 5 – 12. Robofest challenges participants to design, construct, and program robots...
Hi, I am connecting an aircable bluetooth connector http://www.aircables.net/serial.html to the IntelliBrain-based robot and am hoping to form a wireless ...
Hi Tapan, Up to now I made only short feasability checks. (I am now more interestd in programming the gamatronix pid controllers via the I2C bus.) So I cannot...
Hi Tapan, According the the AirCable specifications (see http://www.aircable.net/support-serial.html) it draws 40 mA of current. This is less than 10% of the...
Another customer asked a question similar to Tapan's question regarding powering concerns: Can both the CMPS03 and the SP03 be supported a the same time? ...
When I try to build my program I get a Windows error dialog that jikes.exe has had a problem and would I like to send an error report. Error signature AppName...
I fixed it but don't have a clue what was going on. I determined which class caused the problem by commenting out references to it. I could not see anything...
John, We have seen this or a similar problem when there are a large number of compilation errors. We've found that if you fix the error in the program, jikes...
Hi, I can confirm, that this product works. But everytime I want to connect, there is a need to push the small knob with a screwdriver to start the pairing...
We've found in our testing that once the units are paired they remain paired. Our experience is that the only time you need to reinitiate the pairing...
Hello, The IntelliBrain User Guide says that the digital IO ports 3 through 6 can be used for measuring input pulse durations. We are using these ports for...
Carlos, The IntelliBrain supports a maximum of four pulse measurement inputs. The pulse inputs are implemented using the ATmega128 controller's external...
I tried to compile parts 3, 4 and 5 but had a compiler problem. The error is that abstract Stop method is not realized by the ServoMotor class. I just wanted...
The problem is because the RidgeWarriorII was written using RoboJDE version 1.3. The Motor interface was extended with 1.4 to add the stop method. The method...
Hi in my main program on the robot i am creating a few arrays and populating them however when i run the program it reports a stack overflow exception, what...
Since upgrading to the version of RoboJDE, I am having problems with the CMUcam2. IntilliBrainCMUCam2: Program does not track. Displayed data displays all...
Andy, You probably need to increase the size of the stack for your project. You can set the stack size in the project properties. The greater the call depth,...
Have you tried experimenting with the color range you are tracking with the CMUcam2? The camera is quite sensitive to the color of the object and lighting...
The IntelliBrainCMUcam2 was one of the ones that did not track but returned all zeros. What about the fact that the camera light showed it tracked using two...
Hi, I'm spec'ing out a bot that will use an IntelliBrain controller and one of the CMUCam2 products. My preference would be to use the CMUCam2+ as shown at...
You are correct. The COM2 port supports RS232, not TTL. You will need to use a sensor which has an RS232 interface. RidgeSoft Support ... and ... this ... ...
Hi, I had this problems with other devices (PID motor control) too. I used with success a RS 232 level shifter from www.acroname.com which you can connect to....
Hi im trying to generate a random number using the random.nextInt(int n) method the integer i am passing the method is the leght of an array which contains...
Have you initialized the reference random? For example: Random random = new Random(seed); If you have and you are still having problems, copy and paste the ...
Hans, Thanks for the tip! I'd still end up saving money and weight even with a level shifter in the mix. Doug _____ From: intellibrain@yahoogroups.com...
Hi i am using a pair of bluetooth com port adapters as opposed to the serial cable, i am aware that one of the pins for com2 on the intellibrain can provide...
Andy, +5V is on pin 9 of the DB9 connector. Some earlier boards had a resistor which would limit the current. Newer boards have a 0 ohm resistor so they can...
Hi, In my case the serial Bluetooth module (without external powering) on com1 port on the IntelliBrain and the USB Bluetooth (both from Aircable) on the Host...
