Back to Robobot


Get ROBOBOT and REGBOT source

This is probably installed already, otherwise use

cd
svn co svn://repos.gbar.dtu.dk/jcan/regbot
ln -s regbot/mission
ln -s regbot/robobot_bridge
ln -s regbot/regbotgui
svn co svn://repos.gbar.dtu.dk/jcan/regbot && ln -s regbot/mission && ln -s regbot/robobot_bridge && ln -s regbot/regbotgui

Update and compile

On the raspberry there is the following directories:

$ cd
$ ls
  mission          Mission software skeleton that can also access the raspberry camera
  regbotgui        Configuration GUI for REGBOT (python), a Windows executable can be found in course material.
  regbot/regbot    Firmware for the REGBOT part
  robobot_bridge   The connection software between the REGBOT, the small display, the remote control and the mission software

Update

All these source directories are already connected to a SVN repository, but probably need update, by

cd 
cd mission
svn up
cd ../regbotgui
svn up
cd ../regbot
svn up
cd ../robobot_bridge
svn up

Compile

If there are updates, then they need a recompile (except qtgui).

Mission and Robobot_bridge has a 'build' subdirectory with a Makefile, REGBOT has the Makefile in the base directory.

Type

cd ~/robobot_bridge
mkdir -p build         # make a build directory; -p accepts it may be there already
cd build
cmake ..               # builds Makefile from CMakeLists.txt in parent directory ".."
make -j3               # compile - using 3 CPU cores (not to overheat)
cd ~/mission           # to C++ version of mission control
mkdir -p build         # make a build directory; -p accepts it may be there already
cd build
cmake ..               # builds Makefile from CMakeLists.txt in parent directory ".."
make -j3               # compile - using 3 CPU cores

Start robobot_bridge

The ROBOBOT bridge should start automatically to open the display (showing IP and battery voltage) and optionally also camera streaming (must be installed first)

nano /etc/rc.local

add the following lines before 'exit 0' (close to the end)

# DTU fix for time over blocked network
htpdate -q www.linux.org www.freebsd.org
# start ROBOBOT bridge
cd /home/local/robobot_bridge/build && ./robobot_bridge -a &

REGBOT software

The REGBOT is programmed with Arduino (and Teensyduino) and require these tools to be installed to compile and install the firmware See the installation procedure description in Software_installation.

The REGBOT software is in the ~/regbot/regbot directory

To compile it for the REGBOT version 4 hardware (red board) with a Teensy 3.5 processor board, go to the '3.5' subdirectory

cd ~/regbot/regbot/3.5
make -j4

If successful a regbot.hex file is generated and should be uploaded to the REGBOT Teensy 3.5 processor.

This can be done from a console with X-messages enabled.

ssh -X local@solvej.local

if the robot is 'solvej'.

NB! While programming all the pins on the processor are released, including the one maintaining power to the robot. This means that the red button on the board MUST be pressed during the MAKE UPLOAD command

cd ~/regbot/regbot/3.5
make upload

See the regbot directory for more details.
