A man is seen tapping on a wall, seemingly trying to find something inside it.

A man with a beard and a baseball cap is shown in what appears to be a construction or renovation setting. He is leaning against a white wall, initially tapping it and looking thoughtful. He then takes out a black case with the word "WALABOT" on it. He opens the case to reveal a device, which he then attaches to his phone. He places the phone with the device onto the wall and begins to move it around, indicating he is scanning the wall. The phone screen displays a graphical representation of what the device is detecting. The man then points to the screen, showing that the device can identify studs, pipes, and other objects within the wall.
