Overview

• This is a hands-on project-based course.• You will work in group of 2 on a hardware project.• Each group will propose their design, and implement it.• We will teach you basic concepts for the project. You will also

have a mentor (a professor) to guide you.• We intend to show you and let you experience

• Basic engineering principles and concepts• Experimental skills• Design methodology for design & construction of a system

• We also hope that by the end of the term, you would demonstrate innovations, teamwork, and good communication skills.

History of Design• People have been designing things for a long time• Examples of great designs from the past

• Great Pyramids in Egypt• Mayan Cities and Temples• Great Wall of China

• Basic design method in the past > Trial and Error

The Design Process

• Scientists see things as they are and ask, WHY?• Engineers see things as they could be and ask, WHY NOT?

• Essence of new design• Less expensive• Faster• Better

ENGG 1100 | Term 2 | 2013/14 9

Engineering design addresses hard problems

• Design problems are ill structured— their solutions cannot normally be found by applying math. formulas, methods, and procedures in a routine way.

• Design problems are open-ended— they typically have several acceptable solutions.

The Project

• Your task is to design and build an intelligent car…

Mars Rover Curiosity (source: www.nasa.gov/mission_pages/msl)

ENGG 1100 | Term 2 | 2013/14 11

The Project

• Your task is to design and build an intelligent car…… like these, or something smarter than that.

• To be specific, you are going to design an automatic vehicle with pick-and-place ability. See http://youtu.be/dy_u7lxMkTY

ENGG 1100 | Term 2 | 2013/14 12

The Project

• You are going to design an automatic vehicle with pick-and-place ability.

• Designing an intelligent model car, and implementing a practically working one, takes some amount of effort.

• You will have to learn engineering basics that lead to sensing, control logics for decision making, and motor driving.

An Overview of your Schedule

• First 8 weeks: Learn basic engineering skills• Attend lectures to learn concepts behind designs and electronics;• Attend lab sessions to get hands-on experience with engineering;• Help you understand how to draw mechanical drawings, to build

sensing, digital logics and motoring driving circuitries;• Having your mid term test run to construct your very first design.Note:

don’t just receive the contents. Think how they help you design the car!

• Weeks 10-13: design and build your car• Complete your design by the end of the term;• You will be assigned a tutor and a mentor (a professor) to guide

you.

• Weeks 14: project demonstration• 1 demonstration at reading room

Laboratory

• You will probably spend much of your time in lab.

• The lab. provides you with test instruments, and components for the project.

• Attendance will be checked. Bring your student ID card. • Late with 15 minutes buffer.

• More than 30 minutes late = absence.

• Use of lab. other than assigned lab. hours may be allowed subject to discretion of technicians.

• Log in eLearn for Lab Manuals.

ENGG 1100 | Term 2 | 2013/14 20
