Autonmous design and execution of process controllers for untended scientific instruments

This article examines the changing approach towards the representation of the senses in 17th-century Flemish painting. These changes are related to the cultural politics and courtly culture of the Spanish sovereigns of the Southern Netherlands, the Archdukes Albert and Isabella. The 1617–18 painting-series of the Five Senses by Jan Brueghel the Elder and Peter Paul Rubens as well as the pendant paintings on the subject are analyzed in relation to the iconography of the five senses, and in regard to Flemish genre themes. In this context, the excess of objects, paintings, scientific instruments, animals, and plants in the Five Senses are read as an expansion of the iconography of the senses as well as a reference to the courtly material culture of the Archdukes. Framing the senses as part of a cultural web of artifacts, Brueghel and Rubens refer both to elite lived experience and traditional iconography. The article examines the continuity between the iconography of the senses from 1600 onwards, as developed by Georg Pencz, Frans Floris, and Maerten de Vos, and the representation of the senses in the series. In addition, the article shows how certain elements in the paintings are influenced by genre paintings of the courtly company and collector’s cabinet, by Frans Francken, Lucas van Valckenborch and Louis de Caullery. Through the synthesis of these two traditions the subject of the five senses is reinvented in a courtly context

Considerable Size

The European Space Agency’s (ESA) ExoMars rover has recently been subject to a Phase A study led by EADS Astrium, UK. This rover mission represents a highly ambitious venture in that the rover is of considerable size ~200+kg with high mobility carrying a highly complex scientific instrument suite (Pasteur) of up to 40 kg in mass devoted to exobiological investigation of the Martian surface and sub-surface. The chassis design has been a particular challenge given the inhospitable terrain on Mars and the need to traverse such terrain robustly in order to deliver the scientific instruments to science targets of exobiological interest, We present some of the results and design issues encountered during the Phase A study related to the chassis. In particular, we have focussed on the overall tractive performance of a number of candidate chassis designs and selected the RCL (Science & Technology Rover Company Ltd in Russian) concept C design as the baseline option in terms of high performance with minimal mechanical complexity overhead. This design is a six-wheeled double-rocker bogie design to provide springless suspension and maintain approximately equal weight distribution across each wheel.
