This paper proposes a remote operation method for a robot arm in a complex environment by using the Virtual Force (VF) based approach. A virtual robot arm is manipulated by a steering force, at the end-effecter, which is generated according to the movement of a feedback haptic. A three-dimensional force field (3D-F) is employed in collision detection and avoidance. Repulsive forces from the 3D-...

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...

abstract: in this work, an optimal control scheme with adaptive weighting coefficients is presented which coordinates different vehicle dynamics control objectives, thus ruling out possible conflicts among them. in a new approach, the weighting coefficients in optimal control are adjusted according to the vehicle state in the phase plane in such a way that a priority is given to each objective ...

Modern cars are equipped with both active and passive sensor systems that can detect potential collisions. In contrast, locusts avoid collisions solely by responding to certain visual cues that are associated with object looming. In neurophysiological experiments, I investigated the possibility that the 'collision-detector neurons' of locusts respond to impending collisions in films recorded wi...

We developed a new tactile display using acoustic radiation pressure. The display can produce a 1 mm diameter focal point and 2 gf total force. By steering the focal point using a linear phased array, the display creates various spatiotemporal patterns of pressure distribution on the skin precisely. We carried out experiments on “tactile apparent movement” with the tactile display and found tha...

This proposal was developed primarily by using the open Internet Engineering Task Force (IETF) poisson working group mailing list to discuss successive versions of the proposal. In addition the proposal has benefited from extensive discussion within the IETF’s Internet Engineering Steering Group (IESG) and Internet Architecture Board (IAB). The proposal also benefited from extended discussions ...
