I missed the boat in regards to buying an expansion board, so if
anyone wants to sell their board, I would be willing to pay up to the
original price for the board. Please contact me if you have an extra
WORKING board or know where I can get one. Thanks.

The RoboJDE API is missing the (very useful) System.arraycopy method
which typically provides a high speed native way to copy bytes from
one array to another. Other than a Java for loop to copy the bytes
from one array to another, is there a faster way to do this?

I had seen the info on native code and was going to try to implement a
native System.arrraycopy for my Atmel Intellibrain2 board and found
that native methods aren't supported on this processor - why not?

I created a project on my D: partition and the RoboJDE is installed on
my C: partition. I could compile the project on the D: partition but
not link it - it complained that it couldn't find the .class file. I
moved the project to the C: drive (under the RoboJDE directory) and
now it works fine.

Is there are restriction that projects must be on the same drive as
the RoboJDE, or in the RoboJDE directory?

I searched the forum I did not see the answer to my question.

I just bought a IntelliBrain-Bot Deluxe Educational Robot Kit. Can
this support rechargeable batteries? If it can what types? I also
notice a female power connector on the backside of the robot can I use
this? If I can what is the power adapters specifications I need?

Powering options are discussed in the IntelliBrain 2 User Guide.  See
page 11.

We have recently added a new chapter on line following to our hands-on, introductory Java robotics curriculum, Exploring Robotics with the IntelliBrain-Bot.  The chapter covers:

Hi,

I'm trying to use netbeans to compile programs to download to the IB.
I've unchecked the box for compiling on the projects dialog box and I'm
using the RoboJDE.jar as my first library so the compile in netbeans
seems to be working. I've put the code in a package, which in the past
has screwed me up, but RoboJDE seems to be finding the class files. The
error that I am getting is:

No such method:  com.ridgesoft.intellibrain.IntelliBrain.getModel()
Link failed

The code file is attached. It doesn't explicitly contain a call to
getModel() so I'm confused as to what is going on. Any ideas?

Does it compile and link okay using the RoboJDE GUI instead of
Netbeans?

Hey, how do you synchronize the Aircable and Robo JDE. I mean how you
program your Aircable, the one that is connected to your PC? What is the
format of the data that Robo JDE transfer to this port. Well I assume it
should be a machine code (Assembly Language) only. If I am not wrong
then how do you handle this transferring?

The AirCable simulates a real cable, replacing the wired serial
communication with wireless serial communication.  RoboJDE doesn't know
the difference between the two.  You can learn more about the AirCable
adapters at:  http://www.aircable.net/

The motor driver chip is spec'd to deliver up to 1A per output.  It has thermal shutdown, but it's probably not a good idea to depend on this.

The specs on the driver chip are available here:  http://focus.ti.com/docs/prod/folders/print/sn754410.html

Dear all,
I already follow the testing procedure of new
controller.

>>Rotate the thumbwheel slowly until the LCD screen
displays the readings of
the left and right wheel sensors as follows: L Wheel:
<value> , R Wheel:<value> .

The LCD didn't show the text 'L wheel and  R Wheel'
eventhough I already rotate the wheel.

I already slide the sensor and screw all the way
to the rear end of the slot and extend
the sensor as far over the side of the
chassis as possible, as the instruction command.

When my Robot run 'Navigate Square', he can do it, but
not perfectly square.

Please help.

Thank you

Do you see any text on the display?  Are you turning the thumbwheel
(the black knob next to the serail port connector)?

The IntelliBrain-Bot, as with any robot, has limited precision and is
subject to meeasurement and control errors, such as slippage of the
wheels.  This is one of the challenging aspects of robotics that
makes the field interesting and challenging.

You can improve the precision of the IntelliBrain-Bot's navigation by
upgrading the wheel encoders.  Nubotics makes some very nice encoders.

I've been trying to use packages in roboJDE and am not having much
luck. (Actually, I got it set up to use NetBeans to compile and then
download with RJDE with little luck). I've tried using RJDE with the
no compile option but I am having a tough time setting the directory
properly. Is it possible to link and download from a .jar?

You should be able to link using JAR files.  Just add them to the path
in the project properties in RoboJDE.

Hi,

I've finally gotten back to using my IB to control a TA RC car. The
problem that I am having is that it won't go into reverse. When I use
the RC controller, I have to flip it into reverse twice before it
actually takes but I believe that to be an artifact of the controller
instead of the esc. In any case, I recently got a javelin stamp and used
its servo port to make it go both forward and reverse. When I hooked up
both the IB and the JS to a 'sillicope, I found that the IB has a
slightly shorter period than the JS. This might mean that the esc sees
the pulse as being longer than it really is. When I shortened the pulse
times on the JS, it acted just like the IB does, not going into reverse.
The JS gives you really nuts and bolts access to the servo pwm. Is there
somewhere in the servo code that lets you do the same thing?

Thanks,

wjr

Hi William,

You might try using the Servo interface directly, rather than the
ContinuousRotationServo facade.  This will allow you to experiment with
various pulse widths to see how the ESC responds.  Another option is to
use one of the pulse output ports.  These have more flexibility in terms
of pulse duration and frequency.  To create a pulse train similar to
what the servo ports do, you would have to have a high priority thread
wake up every so often to fire a pulse on the port.

RidgeSoft Support

I tried using Servo directly and it didn't work. However, using a pulse
output port does work. I got the motors to turn both ways. I should know
this but is the threading preemptive or will I need to put in yields to
make sure the motors keep running?

BTW, when I decompiled the jar, I notice the servos are native calls.
Any chance that the parameters to the PWM call are, or could be, public?

Thanks,

wjr

William,

It's preemptive.  All you need to do is give the thread higher priority.

It isn't a simple matter to expose the lower level servo PWM control.
The eight servos are multiplexed off of a single output, which makes it
tightly coupled to the hardware.

RidgeSoft Support

I get a LicenseError:ObjectLimit when i attempt to run my code. The
only way to solve this is to disable some parts. Any suggestions?

Thanks

You need to install the license key.  The key is on the back of the
CDROM case or was sent to you in an email or letter.  Use the Install
License Key item on the RoboJDE Tools menu.

I tried that it still gives me an error

Make sure the user account you are using has write access to the folder
where you installed RoboJDE (e.g. C:\Program Files\RoboJDE).  After you
have installed the license key it should be listed in the Help->About
window.  If it does, but disappears after you exit and restart RoboJDE
it means you don't have write access to the folder where the key is
stored.

I am trying to figure out how the setPower method is implemented in
particular the setPosition method call within setPower().
((power * mRange)/Motor.MAX_FORWARD  + 50)

How is this derived ?
I know mRange varies based on servo.  14 for intellibrain 2
According to Java Doc,  Motor.MAX_FORWARD is +16.
power will be range of +-16

Hi,

I am very much an Eclipse kind of guy, and I've already found on this
forum how to edit and compile within eclipse.  However, I would like to
create an Eclipse plug-in which would allow you to create a RoboJDE
project (automatically loading the correct build path) by right
clicking in the package explorer view.  I also would like to make it
possible to load the program onto the device by adding a "load" button
to eclipse.  The latter will be my biggest obstacle, and so I thought I
would post here to see if anyone knew if you could load a program over
the command line instead of through the RoboJDE GUI.  Any help would be
appreciated.  Also, I'm sure if I get anything working I could make it
available for people to use.

Thanks in Advance,
Jon Heer

How do I build custom cables to interface with Intellibrain controller ?
What is standard awg wire gage for digital inputs ?
What about wire gage for analog inputs ?
What are the type of connectors Hitec, Jr ?
What tools are needed ?
Which vendor specializes in these type cables construction ?
I search and I found cable construction kits for Phone or Cable TV.
