yeah, i was wondering this myself.
the gears generate significant torque, but it’s not like that torque would be delivered solely to the end effector. the nails holding the assembly to the table, the plastic (plastic!) gears themselves, the whole system has to be able to handle the force.
it seems kind of like when superman (or girl) catches a careening airliner, but somehow the ground where our kryptonian is standing is fine, and so are all the people inside the plane.
