We consider a fleet of elementary robots that can be connected in different ways to transport loads of different types. For instance, a single robot can transport a small load and the association of two robots can either transport a large load or two small loads. We seek to determine the number of robots necessary to transport a set of loads in a given time interval, at minimum cost. The cost is function of the number of robots and of the distance travelled by robots. The fleet sizing problem can be formulated by an integer linear problem. In the special case of two types of loads and two configurations, closed-form expressions for the minimum number of robots can be derived. Finally, we show how reconfigurability can allow to diminish the number of required robots.
Electrical signals are an important type of signals in plants, which can not only regulate normal physiological activities, but also reflect the current environmental temperature of plants to a certain extent. The pla...

In semiconductor wafer fabrication, it is incredibly challenging to operate a multi-cluster tool that is composed of several single-cluster tools. This paper deals with the scheduling problem of a time-constrained single-arm-robot multi-cluster tool. We first propose a characteristic single-arm-robot cluster tool and investigate its cyclic scheduling problem. Then, we devise a feature transformation method. By using such a novel approach, a single-arm-robot multi-cluster tool with arbitrary topology can be easily reduced into a characteristic single-arm-robot cluster tool. Thus, the robot tasks are reassigned and then a feasible cyclic schedule can be obtained if the system is schedulable. Finally, we provide illustrative experiments to validate the practicability and availability of the proposed approach.

The continued development of robots has enabled their wider usage in human surroundings. Robots are more trusted to make increasingly important decisions with potentially critical outcomes. Therefore, it is essential to consider the ethical principles under which robots operate. In this paper we examine how contrastive and non-contrastive explanations can be used in understanding the ethics of robot action plans. We build upon an existing ethical framework to allow users to make suggestions about plans and receive automatically generated contrastive explanations. Results of a user study indicate that the generated explanations help humans to understand the ethical principles that underlie a robot's plan.
