Mobile robots that interact with humans in an intuitive way must be able to follow directions provided by humans in unconstrained natural language. In this work we investigate how statistical machine translation techniques can be used to bridge the gap between natural language route instructions and a map of an environment built by a robot. Our approach uses training data to learn to translate from natural language instructions to an automatically-labeled map. the complexity of the translation process is controlled by taking advantage of physical constraints imposed by the map. As a result, our technique can efficiently handle uncertainty in both map labeling and parsing. Our experiments demonstrate the promising capabilities achieved by our approach.

We developed an intelligent agent, RoboLeader, that could assist human operators in route planning for a team of ground robots. We compared the operators' target detection performance in the 4-robot and 8-robot conditions. Results showed that the participants detected significantly less targets and had significantly worse situation awareness when there were 8 robots compared to the 4-robot condition. those participants with higher spatial ability detected more targets than did those with lower spatial ability. Participants' self-assessed workload was affected by the number of robots under control, their gender, and their attentional control ability.

Summary form only given. the STB is capable of engaging manifold affiliation behaviors to build a social rapport toward the goal of collecting trash around an environment. In particular, STB is a child-dependent robot that walks alone in a public space for the purpose of tracing humans and trash and to collect the trash. In a crowded space, STBs move toward the trash by engaging with an attractive twisting motion (behaviors) and vocal interaction to convey STB's intention to children. Our STB robot is incapable of collecting the trash by itself. In this sense, children have to infer a robot's intentional stance or expectation for interaction withthe STB. To collect trash while creating social rapport with children is a novel concept. the STB engages with twisting and bowing motions when children put trash into an STB container (figure 1).

this paper presents the mechanical design, the locomotion and the associated dynamic model of a new robotic wheelchair on climbing winding stairs. the prototype stair-climbing robotic wheelchair is constructed comprising a pair of rotational multi-limbed structures pivotally mounted on opposite sides of a support base so that the robotic wheelchair can ascend and descend stairs; especially, capability of climbing winding stairs is addressed. Based on the skid-steering analysis, the dynamic models for climbing winding stairs are developed for the trajectory planning and motion analysis. these models are required to ensure a passenger's safety in such a way that the robotic wheelchair is operated in an open mode. Numerical and experimental results are reported that show the behavior of the prototype as it climbs a winding stair in a dynamic turning.

this paper suggests a new pattern of human knowledge. Its execution represents an important stage in the general framework of aiming the building of an artificial cognitive system. First the general presentation of the artificial cognitive system, its objective, main principles and implementation phases are highlighted. the known patterns, which have a cultural (philosophical, psychological and linguistic) origin are then analyzed. Finally the details concerning the proposed pattern are pointed out.

this paper introduces an approach for optimizing the production in a manufacturing facility where the work pieces are carried by autonomous robots. For this purpose the process in the facility is modeled as a UML (Unified Modeling Language) activity diagram. thereafter all of the system properties and parameters are added to the model via standard stereotypes and tagged values specified in the MARTE (Modeling and Analysis of Real-time and Embedded Systems) profile. this annotated UML model can be automatically transformed to a corresponding Generalized Net - a summarizing concept of many high-level Petri nets modifications. By accomplishment of simulation experiments with different input parameters the production process can be analyzed and diverse execution scenarios can be compared. In this way an optimal organization in the manufacturing facility can be chosen. this helps in consequence increasing the effectiveness in the facility and reducing the production costs.

Client honeypots visit and interact with suspect web sites in order to detect and collect information about malware. this paper will show the benefits of client honeypots as well as the use of an automated state machine in conjunction with a client honeypot. the state machine provides a powerful framework to organize monitoring of malware activity and record the results. We are developing a platform for integrating client honeypots applied on state machines in a Windows environment.
