Abstract
A robotic arm suction cup capable of eliminating negative pressure is provided. A robotic arm is provided with a first suction cup and a second suction cup of unequal length. Each of the first and second suction cups is connected with a Y-shaped tube. An end of the Y-shaped tube is connected with a communication tube. The communication tube is connected with a vacuum pump. Another end of the Y-shaped tube is connected with a pressure detection tube. A distal end of the pressure detection tube is connected with a pressure detector. The first and second suction cups are not coplanar, and can effectively eliminate the negative pressure between the first and second suction cups and a playing card rapidly, so that the playing card can be separated from the first and second suction cups easily for the game to go on smoothly.
