The aim of this present study is to design a wheelchair with sensor communicator system that could operate the wheelchair with the help of head movement. The targeted people for this study are handicapped person and quadriplegic and disabled person as this could be operated easily through head motion sense. Present study also focuses on reducing the overall cost to make it economically availabl...

Several motion control techniques rely on shape control rather than actuator command. A shape controller speciies the desired shape of the object, but not its position and orientation. The actual position and orientation result from interaction with the surrounding world. We propose to use a bank of wavelet networks, together with local optimization algorithms, as a tunable deformation controll...

Path planning for fixed-wing aircraft in obstacle rich environments requires the consideration of the motion constraints of the aircraft. Most existing motion planning algorithms for systems with dynamics are single query planners, which leads to a large computation overhead if multiple path planning problems are solved. This paper presents a roadmapbased multi-query path planner which generate...

We show that a signature of the quantum nature gravity is mechanical squeezing differential motion two identical masses with respect to their common mode. This because gravitational interaction depends solely on relative position masses. In principle, this equivalent entanglement between practice, detecting more feasible than entanglement. To end, we propose an optical interferometric scheme fa...

Purpose Prostate motion during radiation therapy (ie, intrafraction motion) can cause unwanted loss of radiation dose to the prostate and increased dose to the surrounding organs at risk. A compact but general statistical description of this motion could be useful for simulation of radiation therapy delivery or margin calculations. We investigated whether prostate motion could be modeled with a...

An uncovered bargaining solution is a bargaining solution for which there exists a complete and strict relation (tournament) such that, for each feasible set, the bargaining solution set coincides with the uncovered set of the tournament. We provide a characterization of a class of uncovered bargaining solutions. J.E.L. codes: C72, D44.

One aspect of brainstorming that has received little research attention is how the brainstorming task should be presented to the group, whether as one allencompassing question or as a series of separate questions each focusing on one aspect of the task. This paper reports the results of an experiment in which groups electronically brainstormed on intact tasks (where all parts of the task were p...

Abstract—Biaxial motion stages are commonly used in precision motion applications. However, the contour following accuracy of a biaxial motion stage often suffers from system nonlinearities and external disturbances. To deal with the above-mentioned problem, a control scheme consisting of a reinforcement Q-learning controller with a self-tuning learning rate and two iterative learning controlle...

This paper presents field experiments of two novel approaches to local and regional motion planning applied to planetary rover navigation. The first approach solves the two-point boundary value problem using a model-based trajectory optimization technique that inverts an arbitrary dynamics model to generate a feasible motion plan. The second approach utilizes this result to build a special disc...

To compute a motion trajectory that avoids collisions, reaches a goal region, and satisfies differential constraints imposed by robot dynamics, this paper proposes an approach that conducts a guided search over the continuous space of motions and over a discrete space obtained by a workspace decomposition. A tree of feasible motions and a frontier of workspace regions are expanded simultaneousl...
