Teleop FAQ - umrover/mrover-ros2 GitHub Wiki

Before you look any further, remember to checkout teleop and run ./ansible.sh teleop.yml, followed by ./build.sh.

Python venv

Output

ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? ...

Solution

Enter mrover before trying to run basestation

You have not entered the Python virtual environment. To enter the python venv, enter mrover in the shell. This macro runs:

$ cd ~/ros2_ws/src/mrover && source ~/ros2_ws/src/mrover/venv/bin/activate

which opens the python virtual environment and allows you to run the basestation.

Missing Table

Output

[gui_backend.sh-1] django.db.utils.OperationalError: no such table: backend_currentautonwaypoints

Solution

We need to migrate the Django backend to create the table. From your mrover directory, run:

cd teleoperations/basestation_gui
python3 manage.py makemigrations
python3 manage.py migrate

CMake

Output

From your ./build.sh output:

ZED not found
science_hw_bridge missing

Solution

Some files that CMake expects are missing. You could try and remove the #Perception and #Embedded sections in CMakeLists, and reach out to your team lead for help.

cd && git clone https://github.com/artivis/manif.git
cd manif
python3 -m pip install .
cd ~/ros2_ws/src/mrover
