Abstract
A fruit harvesting apparatus in which the positions of fruit are searched and detected by a television camera with a variable shooting direction. Both the television camera and a spot light emitting device, such as a laser, are varied in position and direction in accordance with instructions to locate a fruit. A movable fruit picker is then moved to the determined position of the fruit and operated to pick the fruit.
Claims6
A fruit harvesting apparatus comprising:
- means for searching and detecting the positions of fruit including a TV camera with a variable shooting direction, a TV monitor for said camera, spot light emitting means for emitting light and means for varying the shooting direction of said camera and the direction of the emitted light and position of said spot emitting means in response to instructions supplied thereto;
- movable means for picking fruit;
- and
- control means for supplying instructions for movement to said TV camera and spot light emitting means, for determining the position of a detected fruit from the direction of shooting of said camera, the position of said spot light emitting means and direction of light emitted by said spot light emitting means by triangulation and causing movement of said fruit picking means to the position of a detected fruit.

A fruit harvesting apparatus comprising:
- means for searching and detecting the positions of fruit including a TV camera with a variable shooting direction, a TV monitor having a screen for producing a display in accordance with the output of said camera and for detecting the position of a probe touching a given position on the screen to select an object, spot light emitting means for emitting light, and means for varying the shooting direction of said camera and the direction of the emitted light of said spot emitting means so that said camera scans on a line extending from said camera in a direction corresponding to the position of said probe on said screen in response to instructions supplied thereto;
- movable means for picking fruit;
- and
- control means for supplying instructions for movement to said TV camera and said spot light emitting means, for determining the position of a detected fruit from the direction in which said line extends and the direction of light emitted by said spot emitting means by triangulation and causing movement of said fruit picking means to the position of a detected fruit.

A fruit harvesting apparatus comprising:
- means for searching and detecting the positions of fruit including a TV camera and a monitor therefor;
- means for memorizing the positions of fruit detected by said searching and detecting means and determining a picking order starting with fruit at a lowermost position;
- movable means for picking fruit including a trap having an upper opening for receiving a fruit to be picked and a plurality of contact sensors disposed about said opening for detecting the positional relationship between a fruit and said opening;
- and
- control means for causing said picking means to be positioned under and at a distance from a fruit to be picked and thereafter to raise said picking means while adjusting the horizontal position thereof so that said fruit to be picked is guided into said trap.
