Mastering WinLogo for Robotics and Control Systems

WinLogo Technology Manual

Introduction

This unit aims to introduce faculty members to the use of computer technology and teach content and sequence control activities within the classroom.

Educational Objectives

This unit is intended to help teachers achieve the following objectives:

• 1. Analyze and decompose a complex problem into simpler components so that the initial problem is solved after addressing each part.
• 2. Use the appropriate methodology to implement the objectives set out in the preceding paragraph with students.
• 3. Use the LOGO programming language for the development of robotics and control algorithms.
• 4. Understand and utilize the controller as a connecting element between the machine and the computer.
• 5. Understand and utilize the interface as a connecting element between the machine and the operator.
• 6. Promote student teamwork through internal group discussions where the teacher acts as a facilitator and instigator of reflections leading to problem resolution.

Logo Basic Primitives

This unit introduces the use of computers; therefore, it requires basic knowledge regarding their operation.

Fundamentals of Logo

This section provides a summary of the Logo language structure and describes a method for introducing students to this programming environment. It provides teachers with the necessary knowledge of Logo to use the language in technology and machine control, specifically in what is known as micro-control.

This section requires practical computer work to complete the guided activities. The Logo language is available in various formats depending on the manufacturer; the most common versions are WinLogo and ActiLogo. WinLogo can be used in both DOS and Windows environments. Since modern software is developed for Windows and its management is highly accessible, this course utilizes WinLogo for Windows.

System Requirements

To run WinLogo, the following elements are required in addition to the standard Windows environment:

• An IBM-compatible computer (386 or better)
• 2 MB of extended memory
• 2 MB of free hard disk space
• Optional printer
• Sound card
