A Microcomputer Controlled Contouring Machine, Kripaker K. Punja
A Microcomputer Controlled Contouring Machine, Kripaker K. Punja
Retrospective Theses and Dissertations
An Apple microcomputer and a three axis milling machine are the basis for a CAD/CAM system with the capability of drilling and contour milling operations. The milling machine axes are driven by three stepper motors under the control of the Apple microcomputer and the ISAAC data acquisition module. An interactive part design program using high resolution color graphics has been developed. It employs lines, circles and points to define the geometry for the part. The design is entered at the CRT and stored as a CAM database on the user disc. Once the design is complete it is postprocessed and …
The Combination Of Artificial Intelligence And Robotics For A Mobile Robot Application, Leslie D. Interrante
The Combination Of Artificial Intelligence And Robotics For A Mobile Robot Application, Leslie D. Interrante
Retrospective Theses and Dissertations
The combination of artificial intelligence and robotics led to more flexibility and powerful mobile robot applications. The robot and its environment were simulated with a microcomputer to gather statistical information. An application was demonstrated in the laboratory with a mobile robot. The robot recognized an obstacle in its path and generated the necessary changes in its environment so that it could successfully complete a required task.
A Mini Apple Network For Apple Ii Plus Computers, Michael E. Harnage
A Mini Apple Network For Apple Ii Plus Computers, Michael E. Harnage
Retrospective Theses and Dissertations
Computer networks have become increasingly popular over the last ten years. A simple low cost Mini Apple Network that uses Apple II plus computers and Apple's Parallel Interface Cards, is presented here. The Mini Apple Network is driven by PIC DRIVER, a software program that is able to transmit an Applesoft array variable from one computer to another. Three application programs are presented. A comparison is made of the gain in execution time when one, two, and three computers are used to solve the same problem, namely Laplace's partial differential equation. An increase in gain was obtained when the number …
An Evaluation Of The 8051 Microcontroller, George C. Schafner
An Evaluation Of The 8051 Microcontroller, George C. Schafner
Retrospective Theses and Dissertations
With the increasing availability and use of 16-bit microprocessors, the 16-bit data bus and is becoming more prevalent. However, many peripheral devices such as printers and tape/disk drives still require an 8-bit data bus for their interface. This paper will explain how an Intel 8051 microcontroller may be used to interface a 16-bit data bus to a peripheral requiring an 8-bit data bus. A FIFO is used to buffer data from a 16-bit processor so that efficient use of processing time is maintained. The 8051 is used to control the peripheral and data transfer.
A Comparative Study Of In-Core And Out-Of-Core Equation Solvers For Microcomputer Applications, Salahuddin A. Siddiqui
A Comparative Study Of In-Core And Out-Of-Core Equation Solvers For Microcomputer Applications, Salahuddin A. Siddiqui
Retrospective Theses and Dissertations
This research evaluates the applicability to microcomputers of various methods for determining the solution of large systems of simultaneous linear algebraic equations. Such systems of equations characterize physical systems often encountered in Civil Engineering and other engineering disciplines. Many methods of solution involving either in-core or out-of-core storage of data have been developed for use with large digital computers. These methods are reviewed and their applicability to microcomputers is evaluated. A comparison of several schemes is made regarding core size required, time of execution, and precision of results. The out-of-core solution schemes for banded matrices are found to be most …
Microprocessor-Based Closed-Loop Control, Man T. Chan
Microprocessor-Based Closed-Loop Control, Man T. Chan
Retrospective Theses and Dissertations
Microprocessor-Based Closed-Loop Motor Control. A dedicated microprocessor control system was built from chip level using the Motorola M6800 family. The system has a keyboard and the interfaces for four LED displays, a phototransistor and a digital-to-analog converter. The system accepts key input in RPM and drives the motor at the input RPM with display of the real RPM updated approximately every second.
An Application Of A Single Chip Slave Microcomputer As An Intelligent Interface, Thomas J. Riordan
An Application Of A Single Chip Slave Microcomputer As An Intelligent Interface, Thomas J. Riordan
Retrospective Theses and Dissertations
This thesis describes the operation of an intelligent controller existing between a computer system and a peripheral. The intelligent controller is implemented with an INTEL universal peripheral interface, UPI-41, single chip slave microcomputer. The interfaces between the controller and the computer system, and the controller and the peripheral are described in detail, as are the firmware and internal facilities of the controller itself. An evaluation of system operation is presented and, finally, the organizational philosophy of the system is discussed. Located within the appendices are a system schematic and listing of the controller program.
Microcomputers: An Alternative For Digital Controllers, Richard Brooke Wavell
Microcomputers: An Alternative For Digital Controllers, Richard Brooke Wavell
Retrospective Theses and Dissertations
Two candidate microprocessors are selected to demonstrate that microprocessors can be effectively utilized in digital control applications. The Intel 8085A-2 is selected to represent 8-bit microprocessors and the Intel 8086 is selected to represent 16-bit. A baseline second order digital filter algorithm is developed for comparison of the performance of the two microprocessors for both software and hardware multiply implementations. Emulation techniques are utilized to facilitate performance comparison, without large investments in software and hardware development. In addition, they provide a method for evaluating new microprocessors, before hardware becomes available. The emulations are then used to verify and to determine …
