Solution

By @chuanchan

The file provided is a binary that runs on Lego Mindstorms EV3. Using this website to get a list of readable instructions. The Lego Mindstorms EV3 has 4 ports to connect to the motor. If you watch the video closely and compare to the picture provided in the description, you'll see that ports B connects to motor lifting or striking the pen, port A connects to motor for vertical stroke, and port C connects to motor for horizontal movements.

Comparing the instructions with the video, it's easy to speculate that port_motor: B | rotations: 35 | speed: -15 strikes the pen, port_motor: A | rotations: 720 | speed: -75 creates a stroke about height of h, port_motor: C | rotations: 2 | speed: 70 create a stroke about width of h. Everytime a character is written, the pen will reset to the left top corner for the next letter. Trying to manipulate the instructions manually, and you will get the flag.

Instructions decoded are as follow
