Abstract

Presents the kinematic calibration of an H4 parallel prototype robot using a vision‐based measuring device. Calibration is performed according to the inverse kinematic model method, using first the design model then a model developed for calibration purpose. To do so, the end‐effector pose (i.e. position and orientation) has to be measured with the utmost accuracy. Thus, first the practical accuracy of the low‐cost vision‐based measuring system is evaluated to have a precision in the order of magnitude of 10μ_it;m and 10−3° for a 1,024×768 pixel CCD camera. Second, the prototype is calibrated using the easy‐to‐install vision system, yielding a final positioning accuracy of the end‐effector reduced from more than 1cm down to less than 0.5mm. Also provides a discussion on the use of such a method on commercial systems.

Abstract

When considering the traditional conceptions of strategy and quality, the links between the two concepts appear sketchy. On the other hand, nowadays, the main streams of thought lead to a necessary and complementary relationship between total quality and strategic management. The pharmaceutical industry, because of the stakes implied by the activity itself, is particularly concerned with the links between quality and strategy: the example of the large European group Merck‐Lipha appears quite significant.

Abstract

Purpose

This paper aims to answer the following question: where does our capacity for epoche, for decentration, for suspending representations come from? This question is an important one if we accept, as phenomenology does, that this is how we can find the meaning of our life and our actions.

Design/methodology/approach

In order to answer this question the paper undertakes a critical genealogy of what those in the Western world consider to be the real, stressing how much Western thought overestimates the reality of what can be seen, measured, and calculated, and underestimates the experience of interiority by silencing the real dynamic of development of each person's lives.

Findings

Following on from Michel Henry's phenomenology the paper shows how epoche, decentring is precisely about paying attention to this very real dynamic of development of life with others. Suspending for a while the representations and calculations and allowing people to be guided by such dynamic is therefore totally justified. Moreover, because it is fully embodied, this dynamic gives us the power and strength to engage in reasonable and responsible action. Two experiences recounted by managers illustrate this point.

Originality/value

The paper shows that phenomenological epoche is not about speculation, it is not idealism, but a totally realistic, practicable choice.

Abstract

Purpose

The purpose of this paper is to clarify the relationship between language, thinking and society for explaining the degree of visibility of the French organizational studies (OS) production.

Design/methodology/approach

This paper proposes a sociological analysis based on Bourdieu field to understand the variation of reception the French OS production have had among the Anglo-Saxon field. The paper aims to underline some key elements, which can explain the differences of reception experienced by the French OS scientists. The paper opted for a general review using historical data; reviews of OS literature; and Google scholar, Web of Science and major OS Journal data.

Findings

The paper provides some evidence about how the degree of visibility of the French OS production is related to translation, cognitive and social resonance, producer place in the scientific network and relationship between the fields. It suggests that the degree of visibility is the result of a complex set of socio-cognitive schemes, social issues raised by the scholar and the place occupied by the researcher in the field.

Originality/value

The paper brings interesting ideas concerning the international development of the OS field, the degree of visibility of diverse contributions coming from non-English speaking researchers, notably the French ones, and how the dialogue between different linguistic and social universes can be ameliorated.

Abstract

Managers as Actors Those of us who manage are playing on an organisational stage every day. We enter early every morning to take up our roles, whether it is as chief executive, marketing manager, personnel adviser, production executive or any of the numerous other roles that have to be performed if work is to be done effectively.

Abstract

Purpose

This article of exploratory research provides a critical perspective on accountability, focusing on three characteristics: transparency, asymmetry and individual agency. An experimental method is developed, calling for an ethics of accountability.

Design/methodology/approach

Four entrepreneurs have given accounts of themselves and their projects in life cycle interviews. This article applies Devereux's approach (1967), which allows for opacity (the “unconscious”) to oneself and to others with symmetry between analysts and analysed, and a lack of demarcation between the observer and the observed.

Findings

A tragic entrepreneurial accountability trap of continuous self-justification was discovered, which pertains both to the entrepreneurs and the researchers. Nonetheless, the researchers as inspired by Devereux's method were able to realize a form of accounterability.

Social implications

This article shows that the demands for transparent, asymmetrical and agentive accountability call for ethical reflection. The request for accounts, as resulting in the accounts given and the research conducted into accountability, are all sources of constraints. Differing the accountability situation may lessen the constraints.

Originality/value

This study introduces Devereux's method as an investigative tool in accountability research, opening up new perspectives on communication and analysis. This article shows the researcher as situated both inside and outside of the accountability mechanisms. This article explores a singular form of accountability; that of entrepreneurs who seemingly only account for the future, thereby disconnecting them from others.

Abstract

Looks at the changes in management science methodology brought about by other fields of knowledge and how this has influenced the views of researchers. Draws the main lessons to be learned from this and thus paves the way for direct observation. Develops a set of prerequisites for in‐company observation which are capable of providing valid insights for management sciences. Concludes that the advantage of such an approach is researchers receive a greater realism and depth to their study of organisational practices which in turn makes the resulting methodology more useable in practice.

Abstract

Purpose

The purpose of this paper is to address the synthesis and experimental application of a generalized predictive control (GPC) technique on an Orthoglide robot.

Design/methodology/approach

The control strategy is composed of two control loops. The inner loop aims at linearizing the nonlinear robot dynamics using feedback linearization. The outer loop tracks the desired trajectory based on GPC strategy, which is robustified against measurement noise and neglected dynamics using Youla parameterization.

Findings

The experimental results show the benefits of the robustified predictive control strategy on the dynamical performance of the Orthoglide robot in terms of tracking accuracy, disturbance rejection, attenuation of noise acting on the control signal and parameter variation without increasing the computational complexity.

Originality/value

The paper shows the implementation of the robustified predictive control strategy in real time with low computational complexity on the Orthoglide robot.
