HAKO

Revision as of 16:29, 2 July 2010

software installation on HAKO

hako 1 - Navigation computer

The navigation computer is primarily running RHD and MRC

Running linux slackware version 12.0 (as of 5 May 2009)

RHD

17 April 2009

Compiled RHD.

Moved to new compiled version (svn 485 from rhd/branches/rhd2.0/build/*)

Moved to /root/hako/rhd484 (including bin, lib and include directories)

cd ~/svn/rhd/branches/rhd2.0/build
tar -czf mrc484.tar.gz bin include lib
scp mrc484.tar.gz root@hako:hako/

on HAKO, make new directoy to new version and move tar file to this

mkdir rhd484
mv rhd484.tar.gz rhd484
cd rhd484
tar -xzf rhd484.tar.gz
cd ..
ln -sf rhd484 rhd
cd rhd/bin
ln -s rhdconfig/rhdconfig.hako.xml rhdconfig.xml

Disable crossbow in rhdconfig.xml (not sufficient stable for real work in this environment)

MRC

17 April 2009

snapshot of MRC (from /vhome/naa/robot2005/src/) to my svn directory on jensen

Changed path of librhd.a in Makefile in mrc subdirectory to:

LIBS= -lrobot -lm /vhome/jca/svn/rhd/branches/rhd2.0/build/lib/librhd.a \
     /vhome/naa/linux/smr/libsmr/libsmr.a \
     -lpthread -lncurses -lexpat -liau_mat

Reference to RHD rhd.h should have moved to

/vhome/jca/svn/rhd/branches/rhd2.0/include/rhd.h

but was not (should be OK), used the version in

/usr/local/smr/include

compiled MRC, and moved it to

scp mrc root@hako:hako/

MRC configuration

17 April 2009

the Hako calibration parameters are in

/root/hako/calib/robot.conf

HAKO old mission manager

Start in browser

Browser with java enabled.

Connect to:

http://192.168.1.10/hako/applet/index.php

Hvis det er første gang, så download 'settings' fil nederst i vinduet, og placer i eget bibliotek som beskrevet. Restart browser.

Vælg så "Hako Control" øverst på php-siden.

Så forbinder java-applet til hakoclient, som starter RHD og MRC på hako-navigationscomputer.

Når forbindelse er etableret og GPS er i fix-mode er status grøn, og klar til at loade en mission.

files

On the HAKO1 computer the mission is placed at

/srv/httpd/htdocs/hako/applet/var/mission.xml

The logfiles can be found in

/srv/httpd/htdocs/hako/applet/log

The newest log is called log. the previous logfile is renamed to YYMMDD--HHMM-log at the time of the new mission.

The logfile has the following entries:

$xkalman
$ykalman
$thkalman
$gpseasting
$gpsnorthing
$odox
$odoy
$odoth
$odovelocity
$hakosteeringangle
$hakocvtpulses

The first log entry has values for $xkalman and $ykalman only. The next line has also $gpseasting $gpsnorthing and from the third line all values should be valid.

NB! the logging is started after the kalman-init period only (before 1 July 2010)

hakoclient

Is called smrdemoclient in the /srv/httpd/htdocs/hako/applet/run directory, but refers to hakoclient in the /home/ex05/src/smrdemo2ext/ directory.

hakoclient can be started manually with the mission XML file as parameter. From the mission directory:

../bin/smrdemoclient mission.xml

The hakoclient source is in the svn (version 1011 as of 30 jun 2010) updated to handle the following issues:

• based on NAA modifications to omegaturn.
• Skipped the last drive on tight omega turns (in file turn_omega.c), to allow faster convergence to next no-turn leg.
• Skipped the last turnr in a fishtail-turn (in functions.c) to allow faster convergence to next no-turn leg.
• Reduced forward drive after first turnr to 20cm (from 0.7m) to make manoeuvre more smooth.
• added a few comments, removed a few unused variables and modified 2 variables from 'int' to 'unsigned int' to remove warnings.
• made a copy of 'stream2line.h' and '-.c' into hakoclient directory to make compilation independent of librobot.a in NAA home directory.

tested 1 july 2010 ad showed clear improvements for both turns.

Stopping and reversing time for the fishtail turn is p.t. bad due to slow CVT control. Fishtail could further be improved with turning while reversing (e.g. using turnr 6 30 @v-1).

hako 2 - Perception computer

Perception computer Is running AU robot servers and works as remote control server

Running linux slackware version 12.0 (as of 5 May 2009)
