Teh "autoporteur" you have is a specifics of French market, in which a manufacturer called "Jeulin" has these huge mobiles that have a blower, a motor and a battery: the battery powers the motor that turns the blower and maintain the whole (heavy!) thing on air to keep it freely moving (on adequate perfect and level surface).
This mobile can create sparks at intervals at the centre of its lower part and thus leave marks on a paper installed on the table; this is its main feature.
This is used in most high school and university physics labs in France, and this is the picture you show. I've been teaching physics some time a go and I have used these items.

If you really want to translate the Jeulin thing, then you may call it a "self-powered mobile".

The rest of the world uses "air tables": the blower and the motor are in the table, that has multiple holes in its surface; then ordinary pucks can "float" freely on this table. Pucks are much lighter and smaller, may vary in size and shape, but cannot leave marks on paper, they need some other equipment to record their movement; see description of their usage with a video camera here:

So the equivalent is probably an air table with pucks to demonstrate Newton's second law elsewhere than in France:

"SECOND LAW – Suppose we attach a rubber band to our air hockey puck. If we stretch
it, the puck starts to move…, if we keep it stretched the same amount, what is the
resulting motion? The speed (really the velocity) of the puck increases uniformly with
time – constant acceleration."
