Complex service robotics scenarios entail unpredictable task appearance both in space and time. This requires robots to continuously relocate and imposes a trade-off between motion costs and efficiency in task execution. In such scenarios, multi-robot systems and even swarms of robots can be exploited to service different areas in parallel. An efficient deployment needs to continuously determine the best allocation according to the actual service needs, while also taking relocation costs into account when such allocation must be modified. For large scale problems, centrally predicting optimal allocations and movement paths for each robot quickly becomes infeasible. Instead, decentralized solutions are needed that allow the robotic system to self-organize and adaptively respond to the task demands. In this paper, we propose a distributed and asynchronous approach to simultaneous task assignment and path planning for robot swarms, which combines a bio-inspired collective decision-making process for the allocation of robots to areas to be serviced, and a search-based path planning approach for the actual routing of robots towards tasks to be executed. Task allocation exploits a hierarchical representation of the workspace, supporting the robot deployment to the areas that mostly require service. We investigate four realistic environments of increasing complexity, where each task requires a robot to reach a location and work for a specific amount of time. The proposed approach improves over two different baseline algorithms in specific settings with statistical significance, while showing consistently good results overall. Moreover, the proposed solution is robust to limited communication and robot failures.

A variable-pitch rotor quadcopter generates thrust in both vertical directions for the special design of the rotor’s actuation mechanism. Flip maneuver sets the rotation matrix of the copter in a singularity that makes the action impossible for common designs based on the hovering dynamics model. Sudden flip was a solution to pass the singularities though that imposes an agile maneuver and excessive energy consumption. This research proposes two possible solutions for the flip: a regulation solution based on the geometric control approach; and tracking a predefined optimal smooth trajectory covering a turnover. The first solution uses a geometric control approach that is immune to singular points since the rotation matrix is integrated into another manifold on SO(3). . The second solution proposes an optimal trajectory generation for flip maneuver using open-loop optimal control, two-point boundary value problem (TPBVP) approach. Since generated open-loop state information is not applicable without a controller, the state-dependent differential Riccati equation (SDDRE) is chosen for trajectory tracking. The backward integration method is employed to provide a solution to the SDDRE with a final boundary condition. The dynamics equation of the variable pitch rot was considered in the simulation to compute the angle of the blades and thrust coefficients. The flip maneuver has been successfully implemented and the optimal trajectory for the maneuver has been obtained and tracked by the nonlinear closed-loop optimal controller. For the regulation case, the geometric control resulted in a smoother flip rather than the abrupt turning of the conventional design.

To understand the meaning of news personalisation strategies to users, we investigated how they currently experience news personalisation, perceive their role in the personalisation process, and envision increasing the utility of personalised news by giving users more agency and fostering trust. We conducted four focus groups with online news readers in Germany. For the analysis, grounded theory techniques were suitable due to their applicability in reconstructing user perspectives through their own experiences. We found that (1) users fail to distinguish between news personalisation and commercial targeting, which may negatively bias their perception; (2) there is a contradiction in how users perceive themselves as active participants in the process, but lack the means to exercise agency; (3) user concerns extend beyond privacy to what information they receive and their right to personal autonomy—a solution requires offering users the ability to dynamically adjust their “news interest profiles”; (4) while news personalisation strategies afford new opportunities for introducing reciprocity in the media-audience relationship, negotiating competing logics of journalistic, personal and algorithmic curation remains a challenge.

We argue that such support is easier to achieve with policy-packages that incorporate primary and ancillary measures. We specifically distinguish command-and-control and market-based measures as primary measures and argue that the former will usually garner more public support than the latter given the low visibility tendency of costs associated with command-and-control measures. Nevertheless, if included in a policy-package, ancillary measures are likely to increase public support by reducing negative effects of primary measures. Based on a choice experiment with a representative sample of 2,034 Swiss citizens, we assess these arguments with respect to political efforts to reduce vehicle emissions. The empirical analysis supports the argument that policy-packaging affects public support positively, particularly generating more support when ancillary measures are added. Lastly, we ultimately observe that command-and-control measures obtain more public support than market-based instruments.

To understand the meaning of news personalisation strategies to users, we investigated how they currently experience news personalisation, perceive their role in the personalisation process, and envision increasing the utility of personalised news by giving users more agency and fostering trust. We conducted four focus groups with online news readers in Germany. For the analysis, grounded theory techniques were suitable due to their applicability in reconstructing user perspectives through their own experiences. We found that (1) users fail to distinguish between news personalisation and commercial targeting, which may negatively bias their perception; (2) there is a contradiction in how users perceive themselves as active participants in the process, but lack the means to exercise agency; (3) user concerns extend beyond privacy to what information they receive and their right to personal autonomy—a solution requires offering users the ability to dynamically adjust their “news interest profiles”; (4) while news personalisation strategies afford new opportunities for introducing reciprocity in the media-audience relationship, negotiating competing logics of journalistic, personal and algorithmic curation remains a challenge.

We argue that such support is easier to achieve with policy-packages that incorporate primary and ancillary measures. We specifically distinguish command-and-control and market-based measures as primary measures and argue that the former will usually garner more public support than the latter given the low visibility tendency of costs associated with command-and-control measures. Nevertheless, if included in a policy-package, ancillary measures are likely to increase public support by reducing negative effects of primary measures. Based on a choice experiment with a representative sample of 2,034 Swiss citizens, we assess these arguments with respect to political efforts to reduce vehicle emissions. The empirical analysis supports the argument that policy-packaging affects public support positively, particularly generating more support when ancillary measures are added. Lastly, we ultimately observe that command-and-control measures obtain more public support than market-based instruments.
