Now, see that less-than-or-equal sign? This says μsN is the maximum static friction force in a given situation. If you push the book with a force of 1 newton, the frictional force will be 1 newton. Double the pushing force and the frictional force also doubles. It does whatever it has to in order to keep the two surfaces stationary—up to a point. If you keep pushing harder, your applied force will eventually exceed μsN and the book will start to slide. At that point, kinetic friction kicks in.

“I don’t think this is a mass-produced toy…Having multiple life-sized copies is even less likely,” u/mindbleach commented. “I expect this is a photo manipulation.” Even if, as suggested, there was only one of the silver robots, snapped in six photos layered over each other, two full-sized robots (with articulating fingers!) are extremely cool. Just look at what the size allowed them to do with lighting and detail in ad number three:
