A Designing of Humanoid Robot Hands in Endo Skeleton and Exoskeleton Styles InTech
Ichiro Kawabuchi.
To contribute on the evaluative process of searching the appropriate designing paradigms as a mechanical engineer, I bring up in this paper some of my ideas about the robot hand design concretely. While the designs of my robot hands may seem to be filled with eccentric, vagarious and serendipitous ideas for some people, I believe they are practical outcomes of flexible ingenuity in mechanical designing, so that they can take on pre-programmed but robust actuating roles for helping the programmable but limited actuators, and realize higher total balance in mechatronics. At the same time, for examining their practicability, reasonability and inevitability through the eyes of many persons, it will need to establish a standard definition and evaluation items...

A Learning Approach for Adaptive Image Segmentation InTech
Vincent Martin; Monique Thonnat.
In this chapter, we have proposed a learning approach for three major issues of image segmentation: context adaptation, algorithm selection and parameter tuning according to the image content and the application need. This supervised learning approach relies on hand-labelled samples. The learning process is guided by the goal of the segmentation and therefore makes the approach reliable for a broad range of applications. The user effort is restrained compared to other supervised methods since it does not require image processing skills: the user has just to click into regions to assign labels; he/she never interacts with algorithm parameters. For the figure-ground segmentation task in video application, this annotation task is even automatic. When all...

Assessing Improvement Opportunities and Risks of Supply Chain Transformation Projects InTech
Alessandro Brun; Maria Caridi.
Over the last 5 years, the model has been applied to more than a dozen manufacturing and service organizations belonging to different sectors. The cases were useful to identify strengths and weaknesses of the methodology. The objectives of completeness and objectivity are reached and many of the hypotheses of relations between management activities and KPIs were confirmed. Yet, the methodology in its present form shown a major limitation, in that the analysis considers as given (and, therefore, deterministic) the characteristics of the APS/SCM solution.

Face Recognition Using Optimized 3D Information from Stereo Images InTech
Changhan Park; Joonki Paik.
This paper proposed a new range-based face detection and recognition method using optimized 3D information from stereo images. The proposed method can significantly improve the recognition rate and is robust against object's size, distance, motion, and depth using the PCA algorithm. The proposed method uses the YCbCr color format for fast, accurate detection of the face region. The proposed method can acquire more robust information against scale and rotation through scaling the detected face image according to the distance change. Experiments were performed in the range of 30~200cm and we could get the recognition rate up to 95.8% according to the scale change. Also, we could get the high recognition rate of 98.3% according to the pose change....

Force Sensing for Multi-Legged Walking Robots: Theory and Experiments Part 1: Overview and Force Sensing InTech
A. Schneider; U. Schmucker.
The control system algorithms and their technical realization for the robots "Masha" and "Katharina" are described in (Schmucker et al., 1996; Schmucker, 2002). Each leg of "Katharina" has its own controller based on a microcontroller INTEL 87C196KR which only controls the respective leg. The controller includes the CPU, FLASH-memory and RAM, a PWM output unit (PWM-U), analog input unit (AIU) and a synchronous serial communication unit (SSCU) on the chip. All microcontroller units are connected by a synchronous serial bus.

Hybrid Ant Colony Optimization for the Channel Assignment Problem in Wireless Communication InTech
Peng-Yeng Yin; Shan-Cheng Li.
In this chapter, we investigate the channel assignment problem (CAP) that is critical in wireless communication applications. Researchers strive to develop algorithms that are able to effectively assign limited channels to a number of cells with nonhomogeneous demands. Inspired by the recent success of metaheuristics, a hybrid ant colony optimisation (HACO) is proposed in this chapter. The HACO embodies several problem-dependent heuristics including ordering, sequential packing, and a local optimiser into an ACO framework. The advantages of this hybrid are two-fold. First, the EMC constraints can be effectively handled by the problem-dependent heuristics instead of using a penalty function as observed in other works which may lengthen the elapsed time in...

In-pipe Robot with Active Steering Capability for Moving Inside of Pipelines InTech
Hyouk Ryeol Choi; Se-gon Roh.
In this chapter we presented the robotic systems MRINSPECT series for a long-distance inspection of pipelines. The systems show outstanding mobility and several characteristic features, which make it possible to apply the proposed systems in pipelines with complicate geometries regardless of the effect of gravity, its postures, and the direction of moving. Though the algorithms were described based on MRINSPECT series, the ideas can be generalized to the other robots. However, according to our experiences on this work, the mechanism of the in-pipe robot should be adaptable to the characteristic condition of the pipelines and it is the preliminary requirement for the successful movement. The use of a general- purpose robot may not be possible in in-pipe...

Mixed-initiative Multirobot Control in USAR InTech
Jijun Wang; Michael Lewis.
In this experiment, the first of a series investigating control of cooperating teams of robots, cooperation was limited to deconfliction of plans so that robots did not re-explore the same regions or interfere with one another. The experiment found that even this limited degree of autonomous cooperation helped in the control of multiple robots. The results showed that cooperative autonomy among robots helped the operators explore more areas and find more victims. The fully autonomous control condition demonstrates that this improvement was not due solely to autonomous task performance as found in (Schurr et al. 2005) but rather resulted from mixed initiative cooperation with the robotic team. The superiority of mixed initiative control was far from a...

PLEIA: A Reconfigurable Platform for Evaluation of HCI Acting InTech
Peralta H.; Monacelli E.; Riman C.; Baklouti M.; Ben Ouezdou F.; Mougharbel I.; Laffont I.; Bouteille J..
Today the methods used by the medical team and occupational therapist are often qualitative. PLEIA software can be employed as a tool to evaluate the pointing user's capabilities. We proposed the new indexes to improve the classical evaluations methods that use the common factors as distance, time, errors and trajectory. The index command load shows the energy that the user employs to act on his technical aid. This energy could be not to be in direct relation with the efficiency, when the user realizes a task. PLEIA's capacities can be expanded as rehabilitation platform, telerehabilitation and experimentation platform for HCI systems with different haptic devices. The experiments are based on the real evaluation cases. In two cases, we evaluated the...

Recognition of Partially Occluded Elliptical Objects using Symmetry on Contour InTech
June-Suh Cho; Joonsoo Choi.
In this paper, we have discussed how to estimate parameters and to reconstruct the occluded shape of partial elliptical objects in image databases. In order to reconstruct occluded shapes, we used mirror symmetry, which provides powerful method for the partial object recognition. Unlike the existing methods, a proposed method tried to reconstruct occluded shapes and regions within objects, since most objects in a domain have symmetrical figures. However, we have limitations in the shape of objects and the occluded region of objects. For example, if a pan has an occlusion in handle, it cannot correctly reconstruct and be recognized. Another minor limitation of a proposed method is that it is sensitive to the pose of an object. For example, if we cannot see...

Robotic Rectal Cancer Surgery InTech
Minia Hellan; Joshua Ellenhorn; Alessio Pigazzi.
Major pitfalls of laparoscopic rectal surgery are the technical and anatomic complexity in the narrow pelvis where some maneuvers are difficult to perform with non-articulating instruments. Because of the potential advantages of robotic assistance in the pelvis, we started to assess the utility of the DaVinci system for total mesorectal excisions. We found that telerobotic surgery facilitates several aspects of the pelvic dissection in the confined pelvic space, and that the three-dimensional imaging gives excellent view of the pelvic anatomy. Early experiences with different robotic-assisted colorectal procedures such as colectomies (Rawlings et al., 2006; D'Annibale et al., 2004), rectopexy (Munz et al., 2004) and anterior resections (D'Annibale et al.,...

Robust and Efficient Robot Vision Through Sampling InTech
Alex North; William Uther.
The high level of detail and dependence upon environmental conditions makes creation of an accurate, robust and efficient robot vision system a complex task. Rather than a traditional focus on colour segmentation of entire images, the vision system outlined in this chapter moves towards detection of local relationships between a subset of the image pixels.

Scheduling for Dedicated Machine Constraint InTech
Arthur Shr; Peter P. Chen; Alan Liu.
We presented the Resource Schedule and Execution Matrix (RSEM) framework?a novel representation and manipulation method for the tasks in this paper. The RSEM framework is used as a tool to analyze the issue of dedicated machine constraint and develop solutions. The simulation also showed that the proposed LB scheduling approach was better than the LS method in various situations. Although the simulations are simplified, they reflect the real situation we have met in the factory. The advantage of the proposed RSEM framework is that we can easily apply various policies to the scheduling system by simple calculation on a two-dimensional matrix. The matrix architecture is easy for practicing other semiconductor manufacturing problems in the area with a similar...

Service Robots and Humanitarian Demining InTech
Maki K. Habib.
The major technical challenge facing the detection of individual mine, is having the ability to discriminate landmines from metal debris, natural clutters and other objects without the need for vegetation cutting. Future efforts to improve detection should focus on providing a discrimination capability that includes the fusion of information coming from multi heterogeneous and homogenous sensors and the incorporation of advanced signal processing techniques to support real-time processing and decision making. For the purpose of mine clearance, there is an urgent need to have cost-effective and efficient clearance techniques to clear landmines in all types of terrains. This should be associated with neutralization, in which there is a need to develop safe,...
