Sensors, robot

When the development of a scientific field expands, the need for handbooks arises, wherein the information that appeared earlier in journals and conference proceedings is systematically and selectively presented. The sensor and actuator Held is now in this position. For this reason, Elsevier Science took the initiative to develop a series of handbooks with the name "Handbook of Sensors and Actuators" which will contain the most meaningful background material that is important for the sensor and actuator field. Titles like Fundamentals of Transducers, Thick Film Sensors, Magnetic Sensors, Micromachining, Piezoelectric Crystal Sensors, Robot Sensors and Intelligent Sensors will be part of this series.

A CCD-sensored robot operated on the basis of an analytical solution of the 3d re-/intersection problem of dimension four is reduced to dimension one by using prior information. Numerical results from an implementation of the closed-form solution of the 3d re-/intersection algorithm on a robot of the Institut fur Informatik, Technische Universitat Munchen are presented. 

The basic positioning techniques on a CCD-sensored robot are threedimensional resection and threedimensional intersection we are going to outline now.

The results can be interpreted as following One pixel perturbation leads approximately to a position perturbation of the order of 5-lOmm. A variation of focal length of the order of 5mm leads to a position perturbation of the order of 20mm. A precise positioning of given points on the robot table is absolutely necessary. An uncertainty of given point coordinates of the order of 1mm forces a perturbation of position of the order of 20mm. For a more detailed experimental study of the CCD-sensored robot Puma 500 we refer to A.Mader (1990).

Optical sensors and relay switches are used throughout the test routine for verification. For all possible problems, as well as the sequence in which they occur, the robot must recognize that there is a problem, define the problem, decide how best to resolve the problem, perform the necessary operations to overcome the problem, and enable the system to resume testing. This is an AI application area and a critical feature, mainly because the system operates unattended and measurements are taken overnight and during weekends. 

Physically, the MIMOS II Mossbauer spectrometer has two components that are joined by an interconnect cable the sensor head (SH) and electronics printed-circuit board (PCB). On MER, the SH is located at the end of the Instrument Deployment Device (IDD) and the electronics board is located in an electronics box inside the rover body. On Mars-Express Beagle-2, a European Space Agency (ESA) mission in 2003, the SH was mounted also on a robotic arm integrated to the Position...

The IDD also carries the a-Particle-X-ray Spectrometer APXS, also from Mainz, Germany, for elemental analysis, the Microscope Imager MI for high resolution microscopic pictures ( 30 pm per pixel), and the RAT for sample preparation (brushing grinding drilling (< 1 cm depth)).

Many sensors have to be integrated into such mobile robotic systems, with a major share of miniaturized, low-power microsystems. Self-guiding features are used in such robots, as well as autocharger docking system features. 

Analytical chemistry in the new millennium will continue to develop greater degrees of sophistication. The use of automation, especially involving robots, for routine work will increase and the role of ever more powerful computers and software, such as intelligent expert systems, will be a dominant factor. Extreme miniaturisation of techniques (the analytical laboratory on a chip ) and sensors designed for specific tasks will make a big impact. Despite such advances, the importance of, and the need for, trained analytical chemists is set to continue into the foreseeable future and it is vital that universities and colleges play a full part in the provision of relevant courses of study.

Second generation robots have sensors, such as cameras, pressure-sensitive or light-sensitive pads, that provide information about their changing external conditions. Sensor information allows the robot to adapt to small changes in its surroundings. 

The sample rack is unique in that it possesses pitch both front to back and side to side. A single robot pick-up point is defined, and an optical (IR) sensor constantly monitors the pick-up point for the presence of a sample. Vials placed in the rack roll down to the pickup point, under the influence of gravity. The rack allows implementation of a novel processing scheme.
