Unfortunately, position control schemes usually fail for tasks that require significant physical interaction between the robot and a workpiece. This restriction severely limits the scope of work that robots are able to do. A solution to this problem is to incorporate some form of compliance into the manipulator to compensate for positioning errors. Researchers have been focused on two principal methods of achieving manipulator compliance - passive mechanism synthesis and active force control - both of which have advantages and disadvantages. In this paper, the authors present recent advances in passive mechanism synthesis algorithms, and investigate the utility of combining a simple, passive mechanism with an active force control scheme to obtain a compliant manipulator with desirable characteristics for interaction control.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

The Kalata relation is obtained from steady state Kalman filter theory assuming zero mean white noise in the position and velocity state equations. The Benedict-Bordner relation is derived based on good noise reduction and good tracking through maneuvers. Both the Kalata and Benedict-Bordner relationships can be derived without any reference to a Kalman filter. The question, given the variety of filter coefficient relationships, is which relationship should be chosen as part of a filter design and why? What does it mean to choose a particular filter coefficient relationship? What is the difference between filter coefficient relationship and a criteria to maximize performance? In this paper, the author tries to give the answer to these questions.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

A specific method for deriving the noise reduction ratios for the alpha-beta and alpha-beta-gamma filters are explored using the Lyapunov equation. This enables us to simplify the computation drastically. For a 2 /spl times/ 2 matrix, one has to solve for one unknown instead of two. For a 3 /spl times/ 3 matrix, one has to solve for three unknowns instead of six and so on. Thus reduction in the number of variables has considerable advantage for higher dimensional filters such as the alpha-beta-gamma filter.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

An eigenspace method for data compression used in the image processing field is commonly referred to as principal component analysis (PCA). We present some recently introduced eigenspace concepts for detecting the pose angle of an occluded object located in an image containing background clutter. To detect the pose of a target object in the presence of background and occlusions we analyze two eigendecomposition methods. The quadtree structure includes dividing the training images into quadrants and creating a subspace eigendecomposition for each level. A statistical robust approach is also applied that weights the background and occlusion pixels based on their influence on the reconstruction of the desired target object. We review both of these pose detection approaches and illustrate each application with an example.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.

This CAC protocol simultaneously satisfies two quality of service (QoS) parameters, namely cell loss ratio (CLR) and delay. The protocol presented is suitable for \"on-line\" application and provides efficient network resource (buffer space and link capacity) utilization. The end-to-end delay and CLR values are divided among the nodes of the connection. Deterministic models that capture the bursty nature of the traffic supported by the ATM network are developed for the source and the network node. These models satisfy the deterministic burstiness constraint required by ATM usage parameter control (UPC). Analytical expressions at nodes for CLR and delay are developed based on these models. These analytical expressions are used to develop a CAC protocol. This CAC protocol for bursty sources is evaluated by using queuing models.","PeriodicalId":309617,"journal":{"name":"Thirty-Sixth Southeastern Symposium on System Theory, 2004.
