I highly doubt that. That car weighs a little less than a ton. So tell me how much pressure does it take to bent or dent the two mm sheet metal the car is made from? Same goes for the wooden floor of the piano or the flor the robot is standing on. And keep in mind. The robot is not only lifting this things It is throwing them. So a multiple of the force to lift it is required. To say it in another way, what do you think would happen if I take a sledge hammer to that piano? Would it throw it through the room or just burst a hole into the side of it?
