Abstract:
A component dispenser (10) comprises a reservoir (30), a dosing volume (40) and a pick surface (80). The component dispenser (10) is configured to displace a selection of components (60) from the reservoir (30) into the dosing volume (40) as a result of a first sequence of movements of the component dispenser (10), and to displace the selection of components (60) from the dosing volume (40) onto the pick surface (80) as a result of a second sequence of movements of the component dispenser (10). The component dispenser (10) is further configured to return any components (60) remaining on the pick surface (80) back into the reservoir (30) as a result of a third sequence of movements of the component dispenser (10). The component dispenser (10) very simple as it is configured to be actuated by external means yet it is well adapted for the task of dispensing components (60) in automated industrial systems.

Abstract:
A method for calibrating a robot system (10) comprising a planar pick surface (90) comprises: bringing a robot gripper (30) to a first location against the pick surface (90); and generating a first image of the robot gripper (30) from below. When knowing that a certain identifiable part of the robot gripper (30) in images always lies against the planar pick surface (90), the position and orientation of the pick surface (90) in relation to a manipulator coordinate frame (70) can be fully defined if the robot gripper's (30) orientation in relation to the pick surface (90) is known, or if there are images on identifiable parts of the robot gripper (30) in at least three different positions against the pick surface (90).
Abstract:
Attachment system (18) for an industrial robot (10), the attachment system (18) comprising a base member(28) having a base (30) and a locking member (32) movable relative to the base (30) between a locking position and an unlocking position; and an attachment member (26); wherein the attachment member (26) comprises an engageable structure (34) configured to be engaged by the locking member (32) when the locking member (32) adopts the locking position, in order to fix the attachment member (26) to the base member (28); and wherein the attachment system (18) further comprises an engaging biasing member (64) configured to bias the locking member (32) towards the engageable structure (34), when the locking member (32) engages the engageable structure (34) in the locking position. An industrial robot (10) comprising an attachment system (18) and a method for handling the industrial robot (10) are also provided.
Abstract:
A method performed by a robotic system (1), for identifying single objects (6) from a random assortment of objects (6). The robotic system (1) picks, among a random assortment of objects (6) on a presentation surface (33), an object (6) from the presentation surface (33) at a determined picking point (42). The robotic system (1) removes any remaining objects from the presentation surface (33). The robotic system (1) places the picked object (6) on the presentation surface (33). The robotic system (1) further analyzes the picked object (6) on the presentation surface (33), in order to identify a single object (6).
Abstract:
A method for identification of a preferred orientation pose for an object comprises the following steps: producing a plurality of images of the object positioned in different orientation poses on a presentation surface (100); forming groups of images that are considered similar to each other, such that each formed group of images represents one orientation pose for the object (200); evaluating the frequency of the images in each group, and thereby obtaining the frequency of each orientation pose(300); and identifying a preferred orientation pose based on the frequency of each orientation pose(400). A component feeder (1) comprises a presentation surface (3) on which objects (5) are presented, and further it comprises an imaging system (7) for producing images of the object when placed on the presentation surface, and a computer unit (50) arranged to form groups of images and to evaluate the frequency of the images in each group.
