1. I find it hard to believe that table weighs 500lbs. If those two engineers are squatting 300lbs each, then they better enter the World's Strongest Man competition.
2. The picture is entertaining, but robots don't push upward, they push sideways. It would be a lot more plausible if they flipped the robot 90 degrees so the robot was holding the table up in the air vertically. If it doesn't slide off, then I'd be impressed.
Suction only increases the normal force between the material and the surface. You still need a material with a high coefficient of friction to resist sliding. Without this, a robot could easily push you off the ramp no matter how much suction you have.
