In this paper we show how a novel photonic remote sensing system assembled on a robotic platform can extract vital biomedical parameters from cattle including their heart beating, breathing and chewing activity. The sensor is based upon a camera and a laser using selfinterference phenomena. The whole system intends to provide an automatic solution for detection, identification and biomedical monitoring of a cow. The detection algorithm is based upon image processing involving probability map construction. The identification algorithms involve well known image pattern recognition techniques. The sensor is used on top of an automated robotic platform in order to support animal decision making. Field tests and computer simulated results are presented.

Design is a contextualized activity influenced by many factors. In order to understand or teach it, a holistic approach that involves students in actual design activities is required. Often, such educational setup is called problem or project-based learning (PBL). There are many views about implementing PBL. Our approach to design education is different than others in the way we treat design courses as products with constraints and objectives. Following our experience in previous design courses, we set to create the best design course possible in our particular context by carefully designing it using design tools developed in design research. We elaborated the course objectives; observed and analyzed failures of design projects in previous courses; and proposed new design methods that could remedy those failures. The collection of potential design methods was evaluated and six methods were selected as the backbone of the design curriculum. The curriculum we designed was implemented in a mechatronic course for high school students. Careful study with several groups including control demonstrated that our design improves the existing course. We describe the course design; provide some details about the design methods that comprise the design curriculum and some examples of using these methods in the course to ground the discussion. A reader unfamiliar with mechatronic could skip these descriptions. The contribution of this paper is twofold. First, we show that there is no single general design methodology. For different products and contexts, different design methodologies should be designed. If we use design methods developed in design research, the methodologies could prove successful. Second, and more specifically, we present a new, possible, and successful design methodology for mechatronics. We are not aware of such comprehensive approach in the literature.

There is general acceptance that an advanced Technology curriculum is needed at the high school level in order to attract students to Technology studies, and in order to promote an insight into the engineering profession. This paper deals with a pilot two-year course "An Introduction to Robotics and Real Time Control", and describes its framework, curriculum and leaming strategy. The course has been given since 1994 in three Israeli high schools and is now officially recommended for wider implementation. Results of a student questionnaire concerning their attitudes towards the course and towards technology as a knowledge and occupational area are presented and discussed.

We present a novel type of model incorporating a special remote life signals sensing optical system on top of a controllable robotic platform. The remote sensing system consists of a laser and a camera. By properly adapting our optics and by applying a proper image processing algorithm we can sense within the field of view, illuminated by the laser and imaged by the camera, the heartbeats and the blood pulse pressure of subjects (even several simultaneously). The task is to use the developed robotic system for search and rescue mission such as saving survivals from a fire.
