Pick And Place

In this paper, we evaluate a semiautonomous brain-computer interface (BCI) for manipulation tasks. In such a system, the user controls a robotic arm through motor imagery commands. In traditional process-control BCI systems, the user has to provide those commands continuously in order to manipulate the effector of the robot step-by-step, which results in a tiresome process for simple tasks such as pick and replace an item from a surface. Here, we take a semiautonomous approach based on a conformal geometric algebra model that solves the inverse kinematics of the robot on the fly, and then the user only has to decide on the start of the movement and the final position of the effector (goal-selection approach). Under these conditions, we implemented pick-and-place tasks with a disk as an item and two target areas placed on the table at arbitrary positions. An artificial vision (AV) algorithm was used to obtain the positions of the items expressed in the robot frame through images captured with a webcam. Then, the AV algorithm is integrated into the inverse kinematics model to perform the manipulation tasks. As proof-of-concept, different users were trained to control the pick-and-place tasks through the process-control and semiautonomous goal-selection approaches so that the performance of both schemes could be compared. Our results show the superiority in performance of the semiautonomous approach as well as evidence of less mental fatigue with it.

Die Anwendung von Aluminium in der Umformtechnik ist in aller Regel mit engeren Prozessgrenzen verbunden – so auch bei der Herstellung von Aluminium-Kunststoff-Verbundbauteilen. Dieser Fachbeitrag thematisiert einen Ansatz zur werkzeugseitigen Prozesssicherung durch einen aktiven Blechhalter. Die Entwicklung und Erprobung erfolgte unter Nutzung eines bestehenden Werkzeugkonzeptes zur Herstellung entsprechender Hybridstrukturen.   The use of aluminum in the forming technology is usually linked to an increasing process instability. This can be shown during the manufacturing of aluminum/plastics composite components. This paper presents an approach for the tool-based process control using an active blankholder. The development and proof of concept was realized by means of an existing tool concept for the manufacturing of those hybrid structures.

Process Execution

Nowadays, business collaborations have to be highly dynamic and flexible to allow companies to operate efficiently and effectively in complex and volatile markets. To increase the business agility of service consumers, it is fundamental that service providers enhance the visibility of parts of their collaborative processes. Service providers are required to release both the process structures of the services offered and their status during execution. To further increase the flexibility of business collaborations, certain control over the process execution has to be offered to service consumers. In this paper, we present a framework for the support of process control in cross-organizational settings. We specify the control primitives that can be used to exert control on activities and processes before, during and after their executions. These primitives empower service consumers to postpone activity and process executions, bypass minor activities, repeat their executions, etc. We describe an approach to the support of these control primitives by service providers. We demonstrate the application of our framework with a case study from the healthcare domain. A proof-of-concept prototype implementation based on Web service technology is presented.
