As robotic systems become more sophisticated, they are increasingly called upon to accompany humans in high-stress environments. This research was conducted to support the integration of robotic systems into tactical teams operating in challenging and stressful environments. robotic systems used to assist tactical teams will need to support some form of autonomy;these systems must be capable of providing operators supervisory control in cases of unpredictable real-time events. An evaluation of the relative effectiveness of three different methods of supervisory control of an autonomously operated mobilerobot system was conducted: (1) hand gestures using a Microsoft Kinect, (2) an interactive Android application on a hand-held mobile device, and (3) verbal commands issued through a headset. These methods of supervisory control were compared to a teleoperated robot using a gamepad controller. The results from this pilot study determined that the touchscreen device was the easiest interface to use to override the robot's next intended movement (L-2(3,23)=11.413, p=.003, d=1.58) and was considered the easiest interface to use overall (L-2(3,23)=8.078, p=.044, d=.93). The results also indicate that the touchscreen device provided the most enjoyable, satisfying, and engaging interface of the four user interfaces evaluated.

In life science laboratories spatially distributed automation systems are increasingly applied to process complex professional tasks of an overall workflow. The transportation-logistic fusion of interacting automation systems is so far often the job of human operators who are parallel involved in regular laboratory tasks. This paper describes the integration of mobilerobots and human operators in a hierarchical workflow management system (HWMS) to increase the degree of automation concerning complex process chains. mobilerobots combine distributed automation systems by labware-transportation processes and enable automated building-wide workflows. The necessity of laboratory assistance for transportation and assistance tasks in these workflows still remains and consequently the flexible integration of human operators, via mobile devices such as smartphones and/or tablet PCs, in the environment of life science automation (LSA) is pursued. Besides the infrastructure for the connection of automation systems (instruments, workstations, integrated systems) also a transportation infrastructure needs to be considered for the workflow control, which distributes and controls transportation and assistance tasks for mobilerobots and human operators. The development of the transportation infrastructure is discussed in detail by three potential variants. The implementation and application of the favored variant is amplified in context with automation systems.

Modern laboratories for life sciences often include several different integrated automation systems to increase throughput and quality, to reduce efforts for human operators and to reduce the costs of processes. Typically, the planning and monitoring of methods are prepared and executed directly on local computers of the automation systems. Moreover, a manual replenishing of resources and a manual transfer of samples and labware between interacting automation systems are required in order to ensure end-to-end operations in a 24/7 mode. This work describes the architecture and the pilot solution of a hierarchical workflow management system (HWMS), which integrates distributed automation systems by combined use of mobilerobots and human operators as transportation units. With a graphical process design tool a material flow-oriented diagram can be created, which describes the correlations of distributed subsystems in a complex workflow. The HWMS schedules the workflows and controls the execution autonomously dependent on the planned process diagrams. Two front-end components located on the process control layer simplify the integration and support the control of the required subsystems. With smart device communications human operators can be integrated in the workflow for transportation and assistance tasks as a necessary alternative to the robots.
