Communication Robots in Real Environments InTech
Masahiro Shiomi; Takayuki Kanda; Hiroshi Ishiguro; Norihiro Hagita.
We have developed an interactive robot system that combines autonomous robots and ubiquitous sensors. The system guided visitors through a science museum with human-like interaction, such as calling their names in a free-play behaviour and explaining exhibits with voice and gestures. In a two-month exhibition, 91,107 people visited the Osaka Science Museum, 11,927 of whom wore RFID tags to participate in the field trial. The results from questionnaires revealed that almost all of the visitors evaluated these robots highly.

Complex Carton Packaging with Dexterous Robot Hands InTech
Venketesh N. Dubey; Jian S. Dai.
The chapter has presented a dexterous reconfigurable assembly and packaging system (D-RAPS) with dexterous robot fingers. The aim of this research was to design a reconfigurable assembly and packaging system that can handle cardboard cartons of different geometry and shapes. The initial idea was to develop such a system that can demonstrate adaptability to cartons of different styles and complexities. It was shown that the packaging machine could fold two cartons of completely different shapes. The cycle time for the folding was approximately 45 seconds in each case. Though this is not an optimized time for folding, it is envisaged to reduce the cycle time to 30 seconds or less with on-line data transfer. Although there are many issues that need to be...

Drum Beating and a Martial Art Bojutsu Performed by a Humanoid Robot InTech
Atsushi Konno; Takaaki Matsumoto; Yu Ishida; Daisuke Sato; Masaru Uchiyama.
This chapter proposed to utilize an impulsive force for humanoid robots to exerts a large force beyond the torque limitations of actuators. The problems of the impact tasks to be solved in the future work were brought up in Section 2. A drum beating is taken as a case study, because it is a typical task that requires large impulsive forces. The details of the drum beating and a Japanese martial art Bojutsu performed by a humanoid robot HRP-2 in the Aichi Exposition were presented in this paper.

Evolutionary Motion Design for Humanoid Robots InTech
Toshihiko Yanase; Hitoshi Iba.
5.1 Optimization using Multi-objective GA In Section4, GA was successfully applied to optimizing the humanoid motions. However, the task is essentially multi-objective optimization. For instance, in case of kicking, we have to consider the trade-off between the stability of the robot and the ball distance. Therefore, we have apply Multi-objective GA (MOGA) (Fonseca & Fleming, 1993) with two fitness, i.e., the chest-link velocity ( Vmax ) and the ball travel distance ( r ). We empirically derive the velocity when the robot falls down and set the value as the velocity limitation of the chest link ( Vlimit ). Rank-based fitness assignment method and niche-formation method are employed to determine the fitness for maximizing ( Vlimit selection is also used...

Multi Robotic Conflict Resolution by Cooperative Velocity and Direction Control InTech
Satish Pedduri; K. Madhava Krishna.
A method by which the velocity and orientation axis of the robot can be dissected into various portions and these portions labeled as conflict free or conflicting with a particular set of robots, unreachable and reachable is presented. The conflict free intervals along the axis that are also represent the solution space for the robot. When the entire reachable space is conflicting with one or more robots it points to the need for cooperation between robots. For a pair of robots that are in conflict with one another and either of them unable to resolve the conflict individually plot of the joint solution space demarcates area where cooperative change of velocities or directions can result in collision freeness. For a pair of robots the entire solution space...

Omnidirectional Mobile Robot - Design and Implementation InTech
Ioan Doroftei; Victor Grosu; Veaceslav Spinu.
Omnidirectional vehicles have great advantages over conventional (non-holonomic) platforms, with car-like Ackerman steering or differential drive system, for moving in tight areas. They can crab sideways, turn on the spot, and follow complex trajectories. These robots are capable of easily performing tasks in environments with static and dynamic obstacles and narrow aisles. Such environments are commonly found in factory workshop offices, warehouses, hospitals, etc. Flexible material handling and movement, with real-time control, has become an integral part of modern manufacturing. The development of an omnidirectional vehicle was pursued to further prove the effectiveness of this type of architecture and to add a ground vehicle platform that is capable of...

On the Analogy in the Emergent Properties of Evolved Locomotion Gaits of Simulated Snakebot InTech
Ivan Tanev; Thomas Ray; Katsunori Shimohara.
We considered the adaptation of evolved locomotion gaits of a simulated snake-like robot (Snakebot) to two distinct changes in the fitness landscape which, in the real-world, are most likely to cause a degradation of the performance of Snakebot ? (i) a challenging terrain and (ii) a Snakebot's partial mechanical damage. We focused on the generality of the locomotion gaits, adapted to these changes in the fitness landscape, and observed the emergence of an additional elevation of the body and increased winding angle as common traits in these gaits. Discovering the strong correlation between the genotypes of the adapted gaits, we concluded that the adaptation is achieved through a drift towards adjacent niches in the genotypic space of the evolving...

"RoboLase": Internet-Accessible Robotic Laser Scissors and Laser Tweezers Microscope Systems InTech
Linda Z. Shi; Michael W. Berns; Elliot Botvinick.
In this paper, the structure and features of the robotic laser scissors and laser tweezers microscope systems are presented. The Robolase systems are shown to be accessible through the internet using the Logmein program, making it feasible to perform biological experiments with remote collaborators. Future developments may involve the creation of separate log-in software for simultaneous use by more than two users/collaborators as well as the use of dedicated fiber-optic lines between different locations. The robotic laser scissors microscope system can be used to ablate a single microtubule and to study the subsequent depolymerization. Ablating of both mitotic half spindles immediately after anaphase-onset was shown to prevent or delay cytokinesis while...

Stereo Vision Based SLAM Issues and Solutions InTech
D.C. Herath; K.R.S. Kodagoda; G. Dissanayake.
In this chapter we have made an attempt to analyse the issues in stereo vision based SLAM and proposed plausible solutions. Correct sensor modelling is vital in any SLAM implementation. Therefore, we have analyzed the stereo vision sensor behaviour experimentally to understand the noise characteristics and statistics. It was verified that the stereo observations in its natural form (i.e. [u,v,d]) can safely be assumed to represent Gaussian distributions. Then several SLAM implementation strategies were discussed using stereo vision. Issues related to limited field of view of the sensor, number of features, spurious features, noise parameters and nonlinearity in the observation model were discussed. It was shown that the filter inconsistency is mainly due...
