Robobot on Raspberry PI

Revision as of 12:06, 24 December 2020

Back to Robobot

Software packages

Install the following paxkages on the Raspberry to get, run and maintain the Robobot software

sudo apt install subversion  # to get the source code
sudo apt install cmake       # to be able co create Makefiles from a specification 
sudo apt install libopencv.dev   # vision library

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

Update ROBOBOT source

On the raspberry there is the following directories:

$ cd
$ ls
  mission          Mission software skeleton that can also access the raspberry camera
  qtgui            Copy of the configuration gui (python files), and a windows executable in the 'dist' subdirectory
  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 directort -p accepts it may be there already
cd build
cmake ..               # builds Makefile from CMakeLists.txt in parent directory ".."
make -j4               # compile - using 4 CPUs
cd ~/mission           # to C++ version of mission control
mkdir -p build         # make a build directort -p accepts it may be there already
cd build
cmake ..               # builds Makefile from CMakeLists.txt in parent directory ".."
make -j4               # compile - using 4 CPUs

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.
