The invention discloses a robot system for rapidly harvesting a bunch of grapes without falling and a realization method thereof. The robot system is composed of a movable chassis, an elevating mechanism, an aerial fruit box device and a small and light-weighted harvest manipulator. A gripper finishes picking, moving the bunch of grapes and vertically placing the bunch of grapes into the fruit boxon an elevating platform nearby.
