説明
A robot consisting of a 3 DOF manipulator, an end-effector, a visual sensor, and a gantry type traveling device was built as a prototype for harvesting strawberry grown on ridge top. In this paper, the mechanism and basic performance of the end-effector for retrieving fruit by vacuum force were described.<BR>The end-effector was developed to suck fruit into an inner cylinder connected to a vacuum device and to cut peduncle by the inner cylinder rotation, and was used for harvesting experiment in a greenhouse. First, an ultrasonic sensor measured distance to ridge top and an image was acquired by a color CCD camera. Secondly, the manipulator moved to a position above a target fruit and the end-effector moved downward to suck the fruit until it was detected by three pairs of photo-interrupters. Thirdly, the inner cylinder rotated and the fruit's peduncle was cut. Then, the manipulator transported the fruit to a tray.<BR>From the experimental results, it was observed that most fruits were sucked into the end-effector at a position 20 mm above the fruits. The fruit sucking method was effective for harvesting small size fruit, because the end-effector could quickly harvest a fruit with no injury to the fruit and could compensate detection error of fruit position from the visual sensor. However, 34% of fruits could not be harvested because some fruits were not sucked and some peduncles were not cut successfully. Improvement of the mechanism of the end-effector needs to be made based on the experimental results.
