Corey has discussed the similarities and differences between synthetic and biological catalysts, coined the term chemzymes for the former, and discussed the connections between these microscopic catalysts and macroscopic robots.

The model considered is that of a unicycle mobile robot (see Fig. 5.2) that has two driving wheels fixed to the axis and one passive orientable wheel that is placed in front of the axis and normal to it [ 19]. 

Theory and numerical methods for the solution of optimal control problems have reached a high standard. There is a wide range of applications, the most challenging of which are from the field of aerospace engineering and robotics see for example the survey paper [5]. 

Although more expensive, the pentafluorophenyl ester is preferred when working with the ASP222 robot (see Chapter 13, Section 4.5).

Ferroelectric—polymer composite devices have been developed for large-area transducers, active noise control, and medical imaging appHcations. North American Philips, Hewlett-Packard, and Toshiba make composite medical imaging probes for in-house use. Krautkramer Branson Co. produces the same purpose composite transducer for the open market. NTK Technical Ceramics and Mitsubishi Petrochemical market ferroelectric—polymer composite materials (108) for various device appHcations, such as a towed array hydrophone and robotic use. Whereas the composite market is growing with the invention of new devices, total unit volume and doUar amounts are small compared to the ferroelectric capacitor and ferroelectric—piezoelectric ceramic markets (see Medical imaging technology). 

The use of "fixed" automation, automation designed to perform a specific task, is already widespread ia the analytical laboratory as exemplified by autosamplers and microprocessors for sample processiag and instmment control (see also Automated instrumentation) (1). The laboratory robot origiaated ia devices coastmcted to perform specific and generally repetitive mechanical tasks ia the laboratory. Examples of automatioa employing robotics iaclude automatic titrators, sample preparatioa devices, and autoanalyzers. These devices have a place within the quality control (qv) laboratory, because they can be optimized for a specific repetitive task. AppHcation of fixed automation within the analytical research function, however, is limited. These devices can only perform the specific tasks for which they were designed (2).

Access to the interior of the enclosure is much more restricted for a total enclosure than for a partial enclosure. So-called totally closed hoods, where all contact between inside and outside is through air locks or by robot or remote control (see Section 10.4.6.4), these are not only expensive to construct and operate, they also need specialized ventilation systems to function properly. 

Fig. 3.3 Solubility profiles of sparingly soluble drugs, based on data taken from Avdeef et al. [20]. The solutions consisted of robotically adjusted universal buffers, based on a mixture of Good buffers (see text), and contained 0.2 M KCl. The dashed lines were calculated by the Henderson-Hasselbalch equation and, as can be seen, did not accurately describe the solubility profiles. The solid curves were...

On the front side of the Rover the robotic arm carrying the Mossbauer spectrometer and other instruments can be seen in stowed position. Right, robotic arm before placement on soil target at Victoria crater rim, Meridian Planum, Mars. The Mossbauer instrument MIMOS II with its circular contact plate can be seen, pointing towards the rover camera. See also Sect. 8.3...

Because of the complexity of sample preparation, backscatter measurement geometry (see Fig. 3.19) is the choice for an in situ planetary Mossbauer instrument [36, 47 9]. No sample preparation is required, because the instmment is simply presented to the sample for analysis. On MER, the MIMOS II SH is mounted on a robotic arm that places it in physical contact with the analysis target (e.g., rock or soil) [36, 37]. 

The MIMOS II Mossbauer spectrometer sensor head (see Sect. 3.3) is located at the end of the /nstrument Deployment Device IDD (see Fig. 8.27) On Mars-Express Beagle-2, an European Space Agency (ESA) mission in 2003, the sensor head was also mounted on a robotic arm integrated to the Position Adjustable Workbench (PAW) instrument assembly [344, 345]. The sensor head shown in Figs. 8.28 and 8.29 carries the electromechanical transducer with the main and reference Co/Rh sources and detectors, a contact plate, and sensor. The contact plate and sensor are used in conjunction with the IDD to apply a small preload when it places the sensor head, holding it firmly against the target. 

The above system of directly sensing a process stream without more is often not sufficiently accurate for process control so, robot titration is preferred in that case by means of for instance the microcomputerized (64K) Titro-Analyzer ADI 2015 (see Fig. 5.28) or its more flexible type ADI 2020 (handling even four sample streams) recently developed by Applikon Dependable Instruments20. These analyzers take a sample directly from process line(s), size it, run the complete analysis and transmit the calculated result(s) to process operation (or control) they allow for a wide range of analyses (potentiometric, amperometric and colorimetric) by means of titrations to a fixed end-point or to a full curve with either single or multiple equivalent points direct measurements with or without (standard) addition of auxiliary reagents can be presented in any units (pH, mV, temperature, etc.) required. 

How could Dawkins have come up with such an extreme and counterintuitive position The source can be found in his analysis of selection. Dawkins (1976) did not introduce the notion of replicators, but he certainly popularized it. Some entities exhibit structures of the sort that deserves to be termed information . Replication is the transmission of this information from one replicator to the next, copies producing copies. In biological evolution, so Dawkins argues, these replicators are genes. He also introduced a second process (environmental interaction) and corresponding entities (vehicles). As Dawkins sees it, the relation between replicators and vehicles is development. Replicators produce the vehicles in which they reside. Vehicles are clumsy robots, totally governed by the replicators that produce them.
