Changed the robot dir to drive and added a dir to work on autonomous mapping

1062 02/27/2009 05:18 PM Justin Scheiner

Small modifications to receive.c, corrected an error
in the ring buffer. Some commenting and cleaning.

1061 02/25/2009 09:04 PM John Sexton

Succesfully tested BOM LED current.

1060 02/25/2009 07:14 PM John Sexton

Corrected Makefiles to work inside the trunk.

1059 02/25/2009 07:03 PM John Sexton

Moved diagnostic station workspace to trunk.

1058 02/25/2009 06:47 PM John Sexton

Moving Diagnostic Station Workspace from branches to trunk.

1055 02/25/2009 05:25 PM Austin Buchan

include path was fixed. AVRDUDEPORT was changed to com4 instead of the usb/tty thingy

1051 02/25/2009 05:21 PM Austin Buchan

Fixed some errors due to BOM being used instead of BOM10

1032 02/17/2009 08:46 PM Justin Scheiner

Having trouble with wireless (I think) hopefully this will work by friday.

1030 02/17/2009 08:28 PM Abraham Levkoy

tested a bunch of different environments for mapping

1029 02/17/2009 08:27 PM Abraham Levkoy

Switched wl_init and wl_set_com_port in test.c (again?)

1028 02/17/2009 07:46 PM Justin Scheiner

Changes all around. Matlab server is now passive, might work soon.

1018 02/11/2009 12:11 PM Abraham Levkoy

Added the data files for real this time

1017 02/10/2009 10:49 PM Abraham Levkoy

Ran some tests in different environments. Data is in 1, 2, 3.txt

1016 02/10/2009 08:00 PM Chris Mar

calls to wl_init() and wl_set_com_port() were inverted

1005 02/05/2009 10:06 PM Abraham Levkoy

test takes an argument for the USB port #, but it doesn't commit a
memory error like it did last time I committed

1004 02/05/2009 09:45 PM Abraham Levkoy

test now takes a second argument for the USB port number

980 01/28/2009 11:42 PM Chris Mar

sorry...didn't mean to commit odometry.c

979 01/28/2009 11:41 PM Chris Mar

minor changes to remote control / mapping code...wireless control works with libwireless reverted to rev. 887. code in odometry interrupt conflicts with motors, not allowing the robot to move motors in response to commands.

970 01/27/2009 08:27 PM Abraham Levkoy

Wrote some code to test wireless communication between the computer and
the robot. Right now, it doesn't work.

967 01/27/2009 06:08 PM Abraham Levkoy

now it will work

966 01/26/2009 07:35 PM Justin Scheiner

Small changes - new file just waits for packets to buffer
for matlab, so the robots will decide when to send their
data in this version.

965 01/26/2009 07:34 PM Abraham Levkoy

Cleaned up test.c and robot_main.c in mapping.

963 01/23/2009 03:58 PM Justin Scheiner

Minor modifications and fixes. Haven't gotten it to work yet.

960 01/22/2009 07:34 PM Justin Scheiner

Small changes and comments.

959 01/22/2009 07:25 PM Justin Scheiner

Changed receive to work when there's no data,
haven't tested for when there is,
test.c works as expected,
Makefile modified to work on receive.c on a linux machine with matlab.
testing robots pending - not hopeful - see code.

958 01/21/2009 07:32 PM Chris Mar

added test for motors. it just runs the left and right. this can be improved.

957 01/20/2009 10:12 PM Justin Scheiner

Slight corrections to this file. I have no way
of testing without a computer with matlab/linux.

If anyone knows windows threading I'd be much
obliged. Alternatively, if anyone knows if there
is an accessible build of gcc higher then version
4 on andrew unix let me know.

954 01/16/2009 04:01 PM Justin Scheiner

Just some test code to see how concurrency works in matlab functions.

953 01/16/2009 03:50 PM Justin Scheiner

Added some test code for the receive function - does not work as
I can't get the token ring to start up. receive.c needs to be on
a matlab computer to be compiled and run correctly (mex receive.c -lpthread)

952 01/16/2009 02:36 PM Justin Scheiner

Wrote mex file code to interface between matlab and the wireless library.

951 01/14/2009 06:30 PM Chris Mar

testing commit on new svn (just template directory)

949 12/10/2008 07:36 PM Justin Scheiner

Added a odometry_velocity function that gives approximate speed of the robot in mm/s.

948 12/10/2008 03:55 PM Justin Scheiner

Added symbolic links to the odometry in mapping to the library, and provided documentation.

947 12/10/2008 03:30 PM Justin Scheiner

Odometry works!!

945 12/02/2008 11:59 PM Austin Buchan

Integrated new BOM1.5 compatible code. Also put eeprom code for reading ID and BOM type from EEPROM. will need to program each robot's eeprom separately later. This has been tested and verified to work on robots with different BOM types.

944 12/02/2008 07:32 PM Chris Mar

added a test for lights/orbs.

940 12/01/2008 07:28 AM Ryan Cahoon

Prototype JNI (Java Native Interface) for libwireless. Compiles, and
java loads the library, but untested with a real scenario or hardware.

939 11/29/2008 08:11 AM Ryan Cahoon

added passing of overhead camera image to client through PHP
fixed unfreed memory in server/vision/savetonetwork.c

938 11/27/2008 06:52 AM Ryan Cahoon

OpenCV now works directly with firewire, coriander is not needed
New vision algorithm integrated, a few issues left with algorithm that
tracks the movement of a specific robot
Removed experimental interface to send images over commands socket
--plan to use php in webserver instead...

937 11/26/2008 09:57 AM Ryan Cahoon

New vision algorithm utilitizing Hough Transform and edge detection
instead of the older one using ellipse fitting and thresholding

936 11/25/2008 05:54 PM Ryan Cahoon

Incremental update; working on:
- new vision algorithm utilizing edge detection instead of thresholding
- sending camera images over sockets instead of using the webserver

935 11/22/2008 11:39 PM Tudor Achim

untested realtime ir plotting

934 11/21/2008 08:20 PM Tudor Achim

Realtime position plotting

932 11/18/2008 11:49 PM Tudor Achim

A working server, with debug printing, some mapping capabilities
Partly for testing

931 11/18/2008 11:44 PM Tudor Achim

changed xbee packet handling, added more info for unexpected packets

930 11/18/2008 09:58 PM Chris Mar

sample maps created by pushing the robot around a table (3 or 4 walls)

929 11/18/2008 09:25 PM Justin Scheiner

Nothing was fixed nothing changed.

928 11/18/2008 09:16 PM Chris Mar

updated server-side mapping code (remote control, etc)

927 11/18/2008 09:16 PM Chris Mar

added odometry to robot mapping code via symlinks to justin's odometry code

926 11/18/2008 09:15 PM Justin Scheiner

Odometry committed. New version is more general, but still drifts to zero.

925 11/18/2008 09:14 PM Chris Mar

cleaning up robot code for mapping

924 11/18/2008 09:00 PM Justin Scheiner

Odometry will temporarily not work. Working code commented out. This commit is so the blight on the world that is
colony math.h will be eradicated for all time.

920 11/18/2008 07:10 PM Ryan Cahoon

Fixed error when getting xbee address during init on computer

919 11/18/2008 06:24 PM Tudor Achim

added model, whoops

918 11/18/2008 06:22 PM Tudor Achim

python stuff

917 11/14/2008 11:12 PM Chris Mar

driving code interprets odometry data correctly, uses non-blocking key listener and can receive packets continually

916 11/14/2008 04:55 PM David Schultz

added ideas on multi-robot behavior
will turn into actual code eventually

915 11/14/2008 12:08 AM Chris Mar

updated robot and server code to use odometry. having problems with theta because it is a double (4 bytes on robot, 8 bytes on server)

913 11/11/2008 09:56 PM Justin Scheiner

Odometry works but the precision is awful. Angles are measured fairly accurately, but distance readings are consistently lower then expected.

912 11/11/2008 08:18 PM Abraham Levkoy

Robot sends updates 50 times per second. Robot remote control program doesn't mess up terminal upon exit.

911 11/11/2008 07:48 PM Chris Mar

fixed output filename and unsigned data

910 11/11/2008 07:29 PM Justin Scheiner

Realized local encoders file was still in the repository.

909 11/11/2008 07:26 PM Justin Scheiner

Quick update before I do something stupid.

908 11/11/2008 07:14 PM Chris Mar

remote control of robot and data output for matlab

907 11/11/2008 06:57 PM Emily Hart

Code that converts data from the robot into a plot

904 11/08/2008 09:30 PM Justin Scheiner

Compiles now. This code worked a while ago but I haven't touched it since early last semester.
The idea was to do exactly what Abe is doing now... so it might be useful.

903 11/08/2008 07:20 PM Chris Mar

added range_init() call to dragonfly_init(). you will no longer have to call range_init() separately in your programs

902 11/08/2008 06:48 PM Tudor Achim

python thingy

901 11/08/2008 06:47 PM Chris Mar

added packet receive functionality to remote control server code

900 11/08/2008 06:11 PM Chris Mar

added remote control to robot code that sends mapping data

899 11/08/2008 05:28 PM Abraham Levkoy

Wireless output works.

898 11/08/2008 03:54 PM Abraham Levkoy

robot_main.c sends the raw sensor data for mapping points to USB. Commented out is untested code to send it over wireless and utilize the (deprecated?) odometry functions.

897 11/08/2008 03:30 PM Chris Mar

code for server with xbee dongle to control robot running slave code

896 11/08/2008 03:29 PM Chris Mar

keyboard remote control code

895 11/07/2008 06:14 PM Brad Neuman

girl scouts!! yay!!!!

894 11/07/2008 04:49 PM Justin Scheiner

Some changes.

890 10/28/2008 07:08 PM Justin Scheiner

Changed some odometry stuff. Interrupt is called now.
Still some problem that is not updating x and y data.

889 10/28/2008 04:55 PM Justin Scheiner

Forgot to add these files to the repository.

887 10/27/2008 09:19 PM Brian Coltin

Updated trunk branch of wireless... Still won't work though because of Makefile.

884 10/24/2008 04:42 PM Justin Scheiner

odometry compiles - timer issues, interrupt never called.

876 10/08/2008 05:57 PM Brian Coltin

Updated libdragonfly makefile.

875 10/08/2008 05:57 PM Brian Coltin

Updated wireless makefile.

874 10/08/2008 04:29 PM Greg Tress

Added comment in discrete controller

872 10/06/2008 04:06 PM Justin Scheiner

Small modifications to odometry. I'm all but committed to using floating point.

870 10/06/2008 03:49 PM Justin Scheiner

Reversed the left wheel. Encoders increment when the robot is moved forward.

868 10/06/2008 03:36 PM Justin Scheiner

Added spi and encoders to the trunk. Tested and worked.
Encoders still read out directions backwards - i.e. there isn't a defined 'direction' for
the encoders to go with the wheels yet. I'll fix this about now.

867 10/06/2008 03:13 PM Justin Scheiner

Added encoder test code to trunk. Addition of encoder code pending testing.

866 10/05/2008 03:41 PM Greg Tress

Fixed file paths in last commit

865 10/05/2008 03:40 PM Greg Tress

Moved files

864 10/05/2008 03:36 PM Greg Tress

Updates to joystick control/slave - attempt 2

862 09/26/2008 02:07 PM Kevin Woo

Updated analog.c and analog.h documentation and regenerated the docs. No need to remake the library as its just comments.

858 09/23/2008 07:25 PM David Schultz

bom/token ring test complete
updated testeeprom #include to make it compile

857 09/23/2008 06:32 PM Brian Coltin

Removed KWoo's crap from template.

853 09/18/2008 10:06 PM Brad Neuman

added eeprom driver and a test for it

848 09/16/2008 08:14 PM David Schultz

Made token ring/BOM test. Currently does not work correctly. Either reports no robots in token ring, or MAXIMUM_XBEE_ID (15) robots in token ring. More testing needed.

836 09/11/2008 07:18 PM Brian Coltin

Brad your fix fails. Reverting. Setting doxygen to output to an absolute path makes it so it will only work on the trac computer. This also breaks the make docs target.

831 09/08/2008 11:05 PM John Sexton

Now have working version of testanalog which prints the table of analog values stored on the robot. Allows us to do analog tests manually and watch the values the robot is reading.

830 09/08/2008 08:35 PM John Sexton

Prints table of the analog values by cycling through all the analog ports and outputting an integer value corresponding to the ADC conversion of that port. Table format needs work.

827 09/08/2008 07:19 PM David Schultz

testrangefinders works.
testanalog gives values, which might mean it works.
