Activity for open day

Install Instructions

As of Jan 2026, all necessary tools / packages are pre-installed on the Diamond Laptops, so there are NO installation steps to carry out. Nonetheless, the installation steps are documented here for future reference.

On The Day

Log in to the offer_holders user account on the Diamond Laptop.

Running the Waffle

The following instructions are copied from here.

waffle X pair

(where X is the waffle we are using)

Type in the password

Then later, in the same terminal:

waffle X term

Then:

ros2 launch tuos_tb3_tools ros.launch.py

In a new terminal, run:

ros2 run rmw_zenoh_cpp rmw_zenohd

Finally: Type Ctrl-B D (this detaches the tmux windows, so the students can't see it).

Running the Web Server

First start another tmux window, type: tmux. Then:

Activate the virtual environment:

source ~/opendaycybersecurity/venv/bin/activate

Launch the activity:

activity

Finally detach the tmux window: Ctrl-B D. This hides the server from the students.

Stopping the Web Server

To kill the web server, use:

pkill activity

(from a separate terminal.)

Using tmux:

tmux ls
tmux a -t 0
Ctrl-B d
