Abstract:
A method and system for piece-picking or piece put-away within a logistics facility. The system includes a central server and at least one mobile manipulation robot. The central server is configured to communicate with the robots to send and receive piece-picking data which includes a unique identification for each piece to be picked, a location within the logistics facility of the pieces to be picked, and a route for the robot to take within the logistics facility. The robots can then autonomously navigate and position themselves within the logistics facility by recognition of landmarks by at least one of a plurality of sensors. The sensors also provide signals related to detection, identification, and location of a piece to be picked or put-away, and processors on the robots analyze the sensor information to generate movements of a unique articulated arm and end effector on the robot to pick or put-away the piece.
Abstract:
Embodiments of the invention include methods and apparatuses for removing a carrier ring assembly from a carrier that includes tightly pitched slots. Embodiments include a robot arm that comprises an end effector wrist, an end effector that has a maximum thickness less than approximately 3.0 mm and a gripping device for securing a carrier ring assembly to the end effector. According to an embodiment, the gripping device may be a clamping member. One or more actuators may be used to displace the clamping member in a direction relative to the end effector. In an additional embodiment, the gripping device may be an electromagnetic device that includes a plurality of electromagnets that are inserted into a top surface of the end effector. Embodiments further include a vacuum gripping device that includes openings in a top surface of the end effector that are coupled to a vacuum controller by air-lines.
Abstract:
Embodiments include methods and apparatuses for transferring and aligning a carrier ring. In an embodiment, a method includes lifting the carrier ring from a first location with a robot arm that includes an end effector wrist and an end effector. Front dowel pins and rear dowel pins are coupled to the end effector. In an embodiment, the end effector wrist includes a plunger that has a gripping device. Embodiments include securing the plunger to the carrier ring with the gripping device and extending the plunger out from the end effector wrist until the carrier ring contacts the front dowel pins. Thereafter, the carrier ring is transferred from the first location to the second location. The plunger and the carrier ring are then retracted until the rear dowel pins engage an alignment notch and an alignment flat on the carrier ring.
Abstract:
A process and tool for installing and removing various kinds of wear parts used with earth working equipment. The process and tool allows the operator to remove and install the wear parts at a safe distance so that the operator is physically remote from the potential risks of the removal and installation process. The tool may be manually operated via an operator or the tool may be a semi-automated or fully automated.
Abstract:
A device and method for adjusting the magnetic strength of a magnetic end effector (100) for lift systems (110) is described. The magnetic end effector is capable of lifting discriminate payloads by selectively varying the strength of the magnetic forces output by the magnetic end effector. An actuator (420) can be operatively coupled to the variable strength magnet end effector, wherein the actuator is selectively actuatable to control the adjustment of the variable strength magnet. The actuator may also be configured to maintain the variable strength magnet at a desired magnetic force output strength once achieved for any given amount of time.
Abstract:
A method for compensating for a perturbation external to a platform having a plurality of mechanical arms in accordance with an embodiment of the technology includes detecting a normal positional and/or orientational measurement of the platform using a sensor. A perturbed positional and/or orientational measurement of the platform can also be detected using the sensor. The normal positional and/or orientational measurement and the perturbed positional and/or orientational measurement can be compared to determine a positional and/or orientational difference. A position and/or orientation of a mechanical arm can be adjusted to compensate for the perturbation based on the positional and/or orientational difference.
Abstract:

The articles (7, 9) at least partially comprising a magnetizable material. The picking member (1) comprises a picking means (2) arranged to take hold of the first article (7). The invention also relates to a separating magnet (3) arranged to facilitate for a taking member (1) to take hold of an article, a method for fetching an article and a robot for fetching an article.
Abstract:
An automated picking apparatus for picking an object disposed on a surface. The automated picking apparatus comprises: a picking device displaceable toward the surface for picking the object; a compensator device co-operably connected to the picking device, the compensator device comprising a first magnet and a second magnet separated by a distance and arranged to repel away from each other; and an actuating mechanism operable for displacing the picking device toward the surface for picking the object, wherein operation of the actuating mechanism activates the compensator device and displaces the picking device co-operably connected thereto; wherein activation of the compensator device reduces the distance between the first and second magnetic elements thereof; and wherein continued operation of the actuating mechanism subsequent to contact between the picking device and the object further reduces the distance between the first and second magnetic elements of the compensator device.
