Low Stiffness

The various relationships that are possible between the mechanical properties of single actuators and the overall mechanism (in this case a human arm with or without a prosthetic elbow) are discussed. Graphical and analytical techniques for describing the range of overall limb stiffnesses that are achievable and for characterizing the overall limb stiffness have been developed. Using a biomimetic approach and, considering energetic costs, stability and complexity, the implications of choosing passive or active implementations of stiffness are discussed. These techniques and approaches are particularly applicable with redundant (agonist - antagonist) actuators and multiple degrees of freedom. Finally, a novel biomimetic approach for control is proposed.

Muscle Fiber Membrane

The aim of this paper is to present the implementation of a method for data acquisition, processing and interpretation of the electrical activity associated with the muscle fiber membrane, generated as a result of the ionic pumps� action. By using a biofeedback shield (EKG/EMG shield) for differential amplification and analog signal filtering, an Arduino development board for analog to digital conversion and an external processing unit, a series of experiments were carried out. These referred to medical diagnosis and research, human-machine interfaces (control of a robotic joint which could be used for prosthetic limbs or industrial robots, as well as control of the computer � for video games, virtual reality, interaction with other devices), and monitoring and increasing sports performance. Due to its noninvasive characteristics, this technique, known as surface electromyography, proves to play a significant role in areas such as medical research, rehabilitation, ergonomics, sports etc.

One Of Ours

The chapter frames Willa Cather’s 1922 novel One of Ours within the context of the US government’s concern about wartime production’s depletion of American forests. Government rehabilitationists and foresters alike sought to place disabled soldiers in forestry-related vocations, which would provide employment and spiritual renewal in nature. These concerns mirror those of Cather’s protagonist Claude Wheeler, who suffers a spiritual amputation at age five when his father cuts down a tree with which Claude had developed an Emersonian kinship. In war he finds spiritual wholeness by offering himself as the prosthetic limbs for those intellectually and artistically superior individuals whom the war has physically and spiritually amputated. Claude’s wholeness comes, ironically, in seeing himself as the trees being cut down for the matériel needed to win the war and civilization to the western world. This self-conceptualization puts him in close company with Italian Futurism, which praises both human mechanization and violence.

This chapter explores four conditions for operationalizing the concept of cognitive extension. (1) Temporal tightness of the coupling—interaction between inner and outer processes must be fast, tight, and fluid, interacting at the speed of thought. (2) External mind parts must be transparent extensions of ourselves like glasses or prosthetic limbs that are psychologically absorbed into the subject’s body sense. We act through these parts or processes rather than on them. (3) Cognitive extensions are “owned”; they are not independent functioning units that could be a source of cognition themselves; inner processes confer cognitive status on the outer. (4) Extended parts or processes interact bidirectionally; causation is reciprocal, though controlled from the biological side. The chapter concludes that extension does exist. Through interaction we create an extended cognitive envelope. The parts of this envelope are episodic processes enacting external thinking rather than being an enduring assemblage of parts. To make the final leap to durable mind parts—external assemblages that are parts of a person even when not in use—requires reasoning of the sort lawyers and judges do best, not scientists.
