Detection and removal of antipersonnel landmines is, at the present time, a serious problem of political, economical, environmental and humanitarian dimensions in many countries over the world. In order to foster robotics research and its applications in the area of humanitarian demining, Minesweepers: Towards a Landmine-free World has been initiated as first outdoor robotic competition on humanitarian demining. This competition aims at raising the public awareness of the seriousness of the landmines and unexploded ordnances (UXOs) contamination and fostering robotics research and its applications in the area of humanitarian demining in the world. In this competition, each participating team constructs a teleoperated/autonomous unmanned ground/aerial vehicle that must be able to search for underground and aboveground anti-personnel landmines and UXOs. The position and the type of each detected object are visualized and overlaid on the minefield map. The robot must be able to navigate through rough terrain that mimics a real minefield. This paper describes this competition, discusses the motivation behind it and summarizes the lessons learned from this initiative.

The scientist and technicians are working to address the social and ethical problems arising due to the development of robotics technology. The ethical challenges include ubiquitous sensing systems, direct neural interfaces, invasive nano-devices, and human-machine interfaces. Roboethics develops scientific, cultural, and technical tools that can be shared by various social groups, to promote and encourage the development of robotics, for the advancement of human society and individuals. Guideleines for the ethical application of robotics to society are based on trans-disciplinary and multi-disciplinary discussions of scientists and scholars. The guidelines apply the precautionary and ethical principles of various other sensitive fields of professional organizations. The governments are continually studying these robot design guidelines and funding projects to produce Roboethics Roadmap.
As a representative of the linear discriminant analysis, the Fisher method is most widely used in practice and it is very effective in two-class classification. However, when it is expanded to a multi-class classifica...

Too often in undergraduate mechanical engineering courses, the content of laboratory exercises is not well coordinated with course content, and the exercises are unrelated to each other. As a result, students have a difficult time grasping the "big picture" themes. This project at Rice University seeks to improve the effectiveness of laboratory exercises in a required undergraduate mechanical engineering system dynamics course via student-centered learning and laboratory topics featuring haptic paddles, devices that allow users to interact via the sense of touch with virtual environments. One outcome of these improvements is a cohesive set of laboratory experiments using the haptic paddles as a single experimental test bed for multiple experiments. The Haptic Paddle exercises are unique because they allow the students to analyze and build their own haptic interface, or force-reflecting system. The students are able to see many subsets of mechanical engineering come together in a series of exercises, including assembly, system analysis, calibration, system modeling, and dynamics. Finally, a key advantage to the haptic paddle labs is that they tie closely with the course material. This paper describes the development of haptic paddle laboratory kits and associated National Instruments LabVIEW virtual instrumentation to support the adaptation of laboratory experiments for a required undergraduate system dynamics course at Rice University. The laboratory experiments use simple haptic interfaces, devices that allow the students to interact via the sense of touch with virtual environments. A clear benefit of this laboratory series is that students study the haptic paddle as a real electromechanical system in addition to using the haptic paddle as a tool to interact with virtual mechanical systems. The haptic paddle hardware has been modified to improve robustness, and the LabVIEW graphical programming language is used for data acquisition and control throughout the labora
