Development of a robot simulation program based on geometric transformation softwares available in most computer graphics systems and program features are described. The program can be extended to simulate robots coordinating with external devices (such as tools, fixtures, conveyors) using geometric transformations to describe the…

Discusses the design and operation of a microcomputer system which obtains and displays an individual's electrocardiogram (EKG). The EKG information, in digital form, can be stored on a floppy disk and transmitted over telephone lines by use of a modem. (JN)

Describes development of an interactive computer graphics program for use in teaching digital signal processing. The program allows students to interactively configure digital systems on a monitor display and observe their system's performance by means of digital plots on the system's outputs. A sample program run is included. (JN)

Describes a simulated computer-aided-graphics (CAD) program at The Pennsylvania State University. Rationale for the program, facilities, microcomputer equipment (Apple) used, and development of a software package for simulating applied engineering graphics are considered. (JN)

Describes phenomena that can be effectively illustrated using microcomputers, techniques used to create these illustrations, and techniques used for displaying them in regular classrooms and over an instructional television network. Also describes microcomputer features required to apply the techniques, providing comments on the suitability of…

Interactive Simulation Language (ISL) is a highly interactive and graphics-oriented language. ISL use in senior design course and introductory system modeling/system behavior course is discussed (including instructional strategies, self-administered instruction, and problem assignment). A description of ISL (including block library and main menu)…

Describes a computer program which allows students to specify rather arbitrary sets of poles and zeros for the transfer function of a linear system. The computer evaluates/plots the systems impulse and step responses individually and displays them in reduced form along with the pole-zero plot. (JN)

In introductory mechanics courses it is often necessary to know the geometric properties of some irregular figure. An interactive program (using an Apple II microcomputer) which allows an instructor to determine the geometric properties of an arbitrary figure is described. Includes mathematical formulation, properties of irregular polygons, and…

Presents computer programs (Applesoft Basic) for: (1) 2-D rotation about any point through any angle; (2) matrix transformation for 2-D rotation; (3) 3-D translation; (4) 3-D rotation; and (5) hyperboloid rotated in 2-D space. Includes background information and sample output for the matrix transformation subroutines. (JN)
