Learning to control arm stiffness under static conditions.
We used a robotic device to test the idea that impedance control involves a process of learning or adaptation that is acquired over time and permits the voluntary control of the pattern of stiffness at the hand. The tests were conducted in statics. Subjects were trained over the course of 3 successive days to resist the effects of one of three different kinds of mechanical loads: single axis lo...
متن کاملEffect of segmental joint stiffness on tunnel lining internal forces under static conditions
According to the wide application of segmental lining in mechanized tunneling, recognizing the behavior of segmental lining joints is important in tunnels designing. In the structural analysis of the tunnel segmental lining, segmental joints can be considered as elastic joints, and their stiffness characteristics are affected by the rotational, shear, and axial stiffness. The purpose of this wo...
متن کاملSemi-static hedging under exchangeability type conditions
In this paper we analyse financial implications of exchangeability and similar properties of finite dimensional random vectors. We show how these properties are reflected in prices of some basket options in view of the well-known put-call symmetry property and the duality principle in option pricing. A particular attention is devoted to the case of asset prices driven by Lévy processes. Based o...
متن کاملStiffness Control of a 1wo-link Flexible Arm
Impact induced transient vibrations of a two-link flexible-arm were attenuated by varying the stiffness of an elbow actuator. Case studies were conducted to determine the effectiveness of the control method as the payload and the elbow angle changed. The suggested method is effective and simple to implement with minimal hardware requirements.
متن کاملVoluntary control of static endpoint stiffness during force regulation tasks.
The goals of this study were to determine the degree to which subjects could voluntarily modulate static endpoint stiffness orientation and to quantify the effects of simultaneously generated voluntary endpoint forces on this ability. Static endpoint stiffness, which characterizes the relationship between externally imposed displacements of the hand and the elastic forces generated in response,...
