A method of using an automated system to position a fabric piece. A pattern is printed onto a fabric piece with fluorescent ink, and detected with a fluorescence-detecting camera, such as a UV camera. The detected pattern is stored in a controller as a pattern signature and compared to a stored target pattern. The results of the comparing step are used to generate control signals for the automated system to move the piece into the position of the target pattern.

A retainer apparatus configured to releasably retain an article, comprising a face plate member each having a front face, a plurality of vacuum cups and a plurality of support pins each extending distally relative to the front face, respectively, wherein the vacuum cups and the support pins are laterally spaced from one another, wherein the plurality of vacuum cups retain the article to the retainer apparatus in a presence of vacuum, wherein the plurality of support pins are extendable/retractable relative to the face plate member, wherein each of the support pins have a longitudinal axis, respectively, and are configured to contact the article to support the article against movement along the longitudinal axis and support the article against movement transverse to the longitudinal axis, and a locking mechanism configured to inhibit the support pins from being retractable and extendable when the locking mechanism is engaged.

Retainer apparatus for movement of articles

An end of arm tool (EOAT) for use during manufacture of parts using one or more pre-impregnated composite plies is disclosed. In an embodiment, the EOAT includes a mechanical gripper arrangement with first and second fingers configured to supply a compressive force to grip a pre-impregnated composite ply therebetween. At least one of the first and second fingers include a roller member to engage opposite surfaces of the pre-preg ply and supply a compressive gripping force. The roller member on either or both the first and second fingers preferably include a torque regulator to selectively adjust an associated roller member's resistance to rotation via supply of a rotational torque resistance.

A dress pack manager for use with a robotic arm having an end-of-arm tool supplied with power or working fluid via a dress pack. A pair of rollers are spaced apart such that the dress pack may pass between them, and such that rotation of the rollers applies friction to the dress pack and causes the dress pack to move. An electric motor rotates one of the rollers in both a forward and backward rotation and is torque-controlled to maintain a constant tension applied to the dress pack by the rollers.

Adaptive dress pack manager for robotic arm

A system and method for printing an image on a surface using a printing robot, wherein data from an internal position determination system of the robot as well as data from a reference system comprising a stationary reference external to the robot are used to calculate an estimate of position, velocity and acceleration of the print head relative to the surface. As print head is moved along the surface during printing, i.e. as the print head is moved while ink is ejected from nozzles of the print head, the positioning of the print head and activation of nozzles of the print head are controlled based on the estimate.

High accuracy printing on a curved surface using fiducial markers and a camera

A method and system for printing an image on a 3D surface is provided, wherein a printing robot is controlled to first carry out an encoder pattern capture run. During this run a print head of the robot is controlled to track an encoder pattern, which may be slightly distorted, on the 3D surface while inertial data from an inertial data measurement unit that is fixed to the print head is stored together with orientational and positional data derived from an image captured of a portion of the encoder pattern that is captured by a camera mounted on the printing head. Next, during a printing run, the print head is controlled such that the camera tracks the encoder pattern for a second time, while printing by the print head and/or a position of the print head is adjusted based on the inertial and orientational and positional data that were stored during the encoder pattern capture run.

The invention relates to a printing device for printing large countoured three-dimensional objects. The printing device comprises a movable robot arm mounted on a movable support, a printhead supported at a printing end of the robot arm, the print head comprising a plurality of nozzles, an ink reservoir connected to the nozzles of the print head and to a pump device for supplying ink from the reservoir to the nozzles, and a controller for moving the print head along a printing trajectory while changing the orientation of the printhead. The controller is arranged for:
