Teleop FAQ

Before you look any further, make sure you have run ./build.sh from the mrover directory.

Python venv

Output

ModuleNotFoundError: No module named 'rclpy'

Solution

You have not entered the Python virtual environment. To enter the python venv, enter mrover in the shell. This function jumps into the repo and activates the build overlay, which opens the python virtual environment and allows you to run the basestation.

CMake

Output 1

From your ./build.sh output:

ZED not found
science_hw_bridge missing

Solution 1

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.

Output 2

./build.sh output gives many missing file errors.

Solution 2

Try updating or deinitializing and then reinitializing git submodules.

git submodule update <submodule>
# or
git submodule deinit <submodule>
git submodule init <submodule>

Submodules include;

• deps/dawn
• deps/manif
• esw/fw

Frontend not loading

Output

Browser shows a blank page or connection refused on localhost:8080.

Solution

Make sure the backend is running (ros2 launch mrover basestation.launch.py). Check the terminal output for errors. If you see bun/npm errors, try:

cd teleoperation/basestation_gui/frontend
bun install

Then relaunch the basestation.

Missing unique_identifier_msgs header

Output

From your ./build.sh output:

fatal error: 'unique_identifier_msgs/msg/detail/uuid__struct.h' file not found

Solution

Run ./clean.sh then ./build.sh from the mrover directory.

manifpy

The manifpy repository is not installed or activated correctly. Try the code below, running from your mrover directory. If that doesn’t work, reach out to your team lead.

sudo apt-get install libeigen3-dev
cd && git clone https://github.com/artivis/manif.git
cd manif
python3 -m pip install .
mrover
git submodule update --init deps/manif
