Fit a lid on a box
Record fitting a lid onto a food container or storage box until it closes.
Possible research use. Lid alignment is a classic insertion problem with tight tolerances. This is a possible use, not a proven result.
How to record. Film 5 to 30 seconds with your hands and the objects fully in frame, from the first movement to the finished task. Use a propped-up phone or a first-person view, keep the area tidy and well lit, and save the clip as MP4 or WebM up to 100 MB. Do not record other people or children, private documents or screens, and avoid anything hazardous.
What the form asks for. Your account email and name, your country, this task example, a short description of the action and objects, the recording perspective and date, optional notes, your video, and five confirmations: you are 18 or older, you recorded it yourself, nobody else appears, no private documents are visible, and you understand the practice terms.
Unpaid practice. This is a practice submission used only to test the platform. It is reviewed, but it is not sold, licensed or included in training datasets, and it earns nothing.
