This paper presents a new approach to C-space exploration and optimal path planning for robotic manipulators and planar scenarios using the structure named bur of free C-space. This structure builds upon the so-called bubble, which is a local volume of free C-space, easily computed using the distance information in the workspace. It is previously shown how burs can be used to form a rapidly exploring...
In this paper we present a decision process to auto-adapt and improve human-machine interaction, simplifying the integration of algorithms and functionalities. The decision process is part of an innovative approach that integrates contextual information to orchestrate behaviours of an interactive system (i.e. perception and actuation features involved during interaction). Classical approaches focus...
This paper proposes a novel hierarchical behavior planner with a multi-layered confabulation based behavior selection structure for robots to perform tasks. The proposed planner integrates a STRIPS based behavior selection approach and cogent confabulation approach. The STRIPS based behavior selection approach is a goal tree search that induces goal-oriented sequences of behaviors, while the cogent...
This paper introduces a graphical interface for Linear Temporal Logic (LTL) specifications for mobile robots. It is a sketch based interface built on the Android platform which makes the LTL control interface more friendly to non-expert users. By predefining a set of areas of interest, this interface can quickly and efficiently create plans that satisfy extended plan goals in LTL. The interface can...
Grey-incidence decision making approach is proposed to deal with the implementation of brownfield redevelopment project in the remediated sites. The inspiration behind this approach is valuable, because it is suitable to use regardless of the sample size. Whether it is big or small, or whether the data fulfills a particular conventional distribution or not. Above and beyond that, what makes it convenient...
This paper proposes a route recommendation system for sightseeing based on a network optimization problem. Sightseeing route planning is not difficult if a tourist initially sets satisfaction values of sightseeing spots numerically. However, it was hard to evaluate the satisfaction values objectively according to the tourist's feelings. The tourist can subjectively do a qualitative and pairwise comparison...
Criteria such as driving safety and overall travel efficiency have led to increasing attempts towards autonomy of vehicles wherein different vehicles can plan their journey, maneuver as per scenario, and communicate to each other to create an error free travel plan. In this paper we present the use of Rapidly Exploring Random Trees (RRT) for the planning of multiple vehicles in traffic scenarios....
We present initial work on a general-purpose system for the analysis of incomplete and uncertain data, integrated with Excel. We explain the representation of main types of uncertainty, and outline tools for the analysis of uncertain data and planning of additional data collection.
Consideration of the preferences of multiple group members is a fundamental requirement for tour route planning. This paper describes the implementation of a tour route planning support system to simplify the planning process. The system recommends combinations of tourist attractions for a group considering the preferences of group members. First, a Kansei database linking tourist attractions and...
We introduce a novel extension to the classic Graphplan. Graphplan is based on the assumption that the initial set of objects is not changeable during planning. This assumption is not true in some cases. That is to say, the planning problems involving creating and destroying objects dynamically canpsilat be solved with classic Graphplan. In this paper, classic Graphplan is extended to solve the planning...
