the content of the paper is focused on the six degrees-of-freedom measurement (DOF) of structural dynamic properties in engineering constructions and for control operation in space. Described measurement system is derived from a pyramid modular sensory system for the sampling of six-component information about three axial shiftings and three angular displacements. the subject of this device is the sampling and information processing used in the conversion of four 2-D CCD arrays images into three axial and three angular displacement values. Every CCD array image consists of one light spot produced by light beam from four laser sources. these light beams form the edges of a pyramidal shape with four 2-D arrays forming its base and the origin of the laser sources is forming its apex. the modular design presented here enables easy customization of six DOF measurement by means of three universal portable modules.

the international Space Station (ISSP) currently under development is equipped with Robotic Workstations to perform and protide information on the Mobile Servicing System robotic functions in use. the workstations include conventional and special developed hardware, software displays, and control software configurations. the robotic activities are critical to the international Space Station during assembly and maintenance activities resulting in detailed crew interface requirements. Operational scenarios were used to develop the requirements of the ISSP Robotic activities resulting in the specification and configuration of the Mobile Servicing System Robotic Workstation.

A dynamically reconfigurable real-time software (DRRTS) paradigm can be used effectively in the design of embedded systems to provide many major advantages over conventional software development techniques. the benefits include rapid development which reduces development time and cost, ability to easily upgrade and maintain embedded software, and both analytic and practical tools for automated analysis and systematic fine tuning of the embedded system. Our current research is founded upon the Chimera Methodology, which demonstrated the feasibility of using dynamically reconfigurable software to control robots. However, there are still many design challenges in order to use it in an embedded system, which has less flexibility, severe limits on memory and CPU bandwidth, and more rigid timing constraints and reliability specifications. We have several ongoing projects which address some of the issues, in a strive towards the overall objective of creating a software infrastructure for developing dynamically reconfigurable embedded software.

A self-organizing controller system is constructed based on artificial neural networks and applied to constant altitude swimming of the autonomous underwater robot PTEROA 150. the system consists of a controller and a forward model which calculates the values for evaluation as a result of control. Some methods are introduced for quick and appropriate adjustment of the controller network. Modification of the controller network is executed based on error-back-propagation method utilizing the forward model network. the forward model is divided into three sub-networks which represent dynamics of the vehicle, estimation of relative position to the seabed and calculation of the altitude. the proposed adaptive system is demonstrated in computer simulations where objective of a vehicle is keeping a constant altitude from seabed which is constituted of triangular ridges.

this paper presents the results of dynamics and control interaction analyses involving the Space Shuttle Orbiter, the Shuttle Remote Manipulator System (SRMS), and the Space Station Freedom (SSF) Attitude control System (ACS) during the SSF assembly operations. the analyses are performed withthe Grumman robotics Analysis Simulation Program (GRASP) which computes nonlinear rigid and flexible multibody dynamics as well as orbital disturbance torques, the SRMS controller, servos and brakes, and the SSF controller which consists of Reaction control System (RCS) jets and control Moment Gyros (CMG). Specific studies include berthing of the Space Station stage vehicle to the Orbiter and installation of pressurized modules such as the node and the U.S. Laboratory module onto the stage vehicle. Results of the study include the SRMS payload positioning and attitude accuracy while performing maneuvers under a variety of control conditions, RCS firings, and CMG momentum management. the analyses show the ability of the SRMS to handle large payloads and the importance of modeling the flexibility and controller dynamics of Space Station Freedom as well as the robotic manipulator.
