A robotics project involving the production of a prototype automated assembly line for a complete garment is described. The line is designed for assembling men's Y-front and ladies' briefs. The problem is subdivided into component-based assembly, folding and closing operations, and a supervisory computer system. Each assembly operation is described with justification behind each proposed solution. The results of operations that have already been implemented are included and assessed. The relationship between the manual operation and the robotics tasks are discussed. Suggestions as to how this system can be applied to products of a similar nature are included

R. S. Wallace, D.G. Taylor
The balanced commutator method of computing the reference currents for current tracking feedback is presented. For a given switch reluctance (SR) motor, the commutator reduces the peaks and the rate of change of the reference currents. This allows accurate current tracking, and therefore minimum torque ripple, over a wider range of operating speeds. Reference current waveshapes for two different SR motors, and the resulting torque ripples, are compared

The decentralized Bayesian detection problem is considered. Some of the design aspects and an analysis of the optimum minimum-cost system are presented. The design of the optimum system is based on an alternate representation of the minimum achievable cost. Using this representation the design of the decentralized Bayesian problem reduces to the optimization of a single function of n variables, thus avoiding the exponential dependence of the cost on the number of variables. The cases of nonidentical as well as identical detectors are treated. Several numerical examples are included

An approach to data representation in mobile robot models is described. In this method, the application is modeled using a stepwise modeling principle. System modeling determines the two basic models of the application: a functional model and a data model. These models are used to represent the functions and data structures of the mobile robot

The requirement for an almost strictly positive real system is part of the stability analysis of the simplified adaptive controller. The relation between this property and strict positive realness is examined for structures with collocated position/velocity sensors and actuators. A numerical procedure is developed to determine whether a given system is almost strictly positive real, and its application is illustrated with an example

A technique based on additive cancellation of opposite phase ripples to obtain a flat frequency response in the pass and stop bands is described. O. Herrmann's formulation (1970) using the Newton-Raphson iterative technique is used to arrive at the design of additively inverse filters which when added together yield a highly flat frequency response filter. Although only low-pass filters were used, the results are applicable to the design of other finite-impulse-response filters

The origin and geometrical characteristics of auto- and cross-components in the Wigner distribution (WD) are investigated utilizing a probe signal. Techniques for eliminating cross-components are reviewed and compared. These methods include local smoothing of the WD using Gaussian and other kinds of smoothing windows, adaptive variation of the smoothing window parameters according to the signal's structure, and the use of singular value decomposition. All the techniques discussed involve a tradeoff between the cross-components and the time-frequency resolution. Ways of avoiding this tradeoff are discussed

The effect of a twist dimension on the dexterity of double pointing systems is studied. It is found that as the twist increases from 0° the dexterity of the double pointing system is continually reduced. However a twist dimension of up to 81° allows for a dexterous exoskeleton shoulder joint workspace large enough to accommodate the range of shoulder joint motion in the typical human. This amount of twist greatly simplifies the design of the shoulder joint exoskeleton, allowing room for hardware such as gearing

A 2D fast Fourier transform (FFT) algorithm is described. This algorithm offers a way to do 2D FFTs in both dimensions simultaneously. The amount of computation is reduced compared to traditional algorithms. Due to its good parallelism, a special arrangement of parallel processors saves a great deal of running time. This algorithm can be extended to discrete-time Fourier transforms in more than two dimensions
