Presentation Transcript

  1. ES 140-8: EE Module 3 MWF 12:10-1:00 FGH 244 and 238 (Lab) Lecture 3: Introduction to Robot Design, Introduction to Lab Dr. K, Kevin and Stephen Department of Electrical Engineering and Computer Science Fall 2008

  2. Today’s Session • Introduction to Assembly and Trouble Shooting • Introduction to Lab • Lab Instructions by Kevin and Stephen

  3. Robot Design and Test In this module, we will learn - mobile robot assembly, - trouble shooting, and - control (e.g., when to stop or turn robot)

  4. Major Components of Robots • Body (plates, gears, motors, wires, etc.) • Power source (battery) • Controller (circuit board) • Sensors (LED, microphone, infra-red )

  5. Introduction to Lab • Team Formation and Naming - Based on the survey, we have formed teams of 3 and assign robot kits. - Today those teams working with Kevin will go to lab. The rest will stay here and work with Stephen the lecture. - If you find someone who agrees to swap with you, you may do so. Let TAs know of any change.

  6. DailyLog At the end of each lab, you will enter the day’s activity in your log sheet. (Assign a recorder each day.) Introduction to Lab

  7. Daily Log • ES140 Laboratory Daily Log • Team Name: ______________________ Date: _________________ • Names: Signatures: • 1, ________________________________ _________________________________ • 2, ________________________________ _________________________________ • 3, ________________________________ _________________________________ • 4, ________________________________ _________________________________ • Work done and equipment used: • Problems Encountered and Solutions: • Observations, opinions, suggestions: • Please write your name and sign after your comments in each block. • If you need more space, ask your TA.  • Recorded by, • --------------------------------------------------------------------------------------

  8. Team Report - TeamReport will include the daily log sheet. Guidelines for Team Report will be given later. - Team Report will be due on or before Tuesday, December 9th. Introduction to Lab

  9. Robot Contest will be conducted towards the end of the module. Detail contest guidelines will be announced later. Robot Contest

  10. Important Guideline for Robot Assembly • Use Patience! The phrase “haste makes waste” is certainly true here. • Make sure to identify and take inventory of all parts!

  11. Important Guideline for Robot Assembly • Use Patience! The phrase “haste makes waste” is certainly true here. • Make sure to identify and take inventory of all parts! • Use the proper tools! Ask your TA if you have questions! • Return any tools you used to where they were originally stored. Ask your TA if you don’t know where to return.

  12. Important Guideline for Robot Assembly • Use Patience! The phrase “haste makes waste” is certainly true here. • Make sure to identify and take inventory of all parts! • Use the proper tools! Ask your TA if you have questions! • Double check your and other member’s work! Before you proceed with an instruction, make sure you understand it. • Help each other!

  13. Lab Cleanup • Use Patience! The phrase “haste makes waste” is certainly true here. • Make sure to identify and take inventory of all parts! • Use the proper tools! Ask your TA if you have questions! • Double check your and other member’s work! Before you proceed with an instruction, make sure you understand it. • Keep lab daily log! • Clean up your workspace before you leave the lab!

  14. Robot Kits to be used • Graymark 601A Sound Controlled Robots “Scooter” Scooter incorporates many of the basic elements of electrical and robotic technologies. It is a motorized vehicle with a microprocessor connected to a logic circuit. It “hears” a loud sound (most of the time). • Graymark 606A Robot Walker The Robot Walker also incorporates many of the basic elements of electrical and robotic technologies. It has six “legs” for navigation. It “detects” the presence of objects using a light sensing device. • Graymaker 602A Blinky Line Tracer Robot. This robot uses feedback control to follow a line. Tricky to make it work.

  15. Introduction to Robot Kit Assembly (1) • 601A Wiring Connections (p. 16)

  16. Introduction to Robot Kit Assembly (1) • Caution: Wiring proper parts into proper places is bit tricky. Go over the wiring connetions instruction in the manual carefully. Ask your TA of nay questions. • Ex. 601A Wiring Connections (p. 16)

  17. Introduction to Robot Kit Assembly (2) • Mounting Steering and Battery Holder Assembly • Ex. 601A (p. 15) Caution: • Make sure that the Battery Holder is tightly screwed to the base plate.

  18. Introduction to Robot Kit Assembly (3) • Printed Circuit Board Construction • This is one of the critical steps in your robot assembly. If you insert a part into a wrong place and replace it, the board often delaminated and this will lead to a mulfunctioning robot!

  19. Introduction to Robot Kit Assembly (3) • Printed Circuit Board Construction This is one of the critical steps in your robot assembly. If you insert a part into a wrong place and replace it, the board often delaminated and this will lead to a mulfunctioning robot! Caution: Spend extra time to study where a particular part will go before you attach to the board!

  20. Circuit Diagram • A schematic diagram showing each circuit element is represented by a graphical symbol. • Ex. ResisterCapacitor Motor

  21. Theory of Sensing and Control • Each manual contains a block diagram in which major sections/functions of robot components are represented by blocks. • Ex. Block Diagram for 601A Scrambler Robot

  22. Today’s Lab (Kevin and Stephen) Agenda: • Discussion of Lab rules, safety etc. • Discussion of Lab Log • Guidelines for soldering • Parts Identification/Inventory

  23. Important Guideline for Today’s Lab • Use Patience! The phrase “haste makes waste” is certainly true here. • Make sure to identify and take inventory of all parts! Caution: - Bags containing parts are difficult to open. Use scissors to open them. - Use extra bags your TA will provide to keep parts.

  24. Today’s Lab Resistor Color Code:

  25. Assignment #3 Homework Assignment #2 • 1 Read the Theory of Operation in the Graymark robot assembly manual. Using one of the following block diagrams, describe how each component works (20 points): - Fig. 2 on p.7 in the 601A Manual, - Fig. T1 on p. 17 in the 606A Manual, or - Figs. A1 and A13 in the 602A Manual.

  26. Assignment Homework Assignment #3 – Part 2 Insect Robot Design • 2.Answer the following regarding the insect robot you propose to design. (a) Sketch a rough design of the robot insect. Make sure to include key dimensions. (10 points) (b) Describe how it senses the environment . (10 points) (c) What is a mechanism for navigation? (10 points) • Due: 12:10pm, Friday, October 17 • Make sure to staple answers together.
