  3. Syllabus and Course Outline • ABET 2000 Compliant Course Description • ENGR 1101 Introduction to Engineering • Catalog Description: Provides an understanding of the study and practice associated with civil, electrical and mechanical engineering technology disciplines. Emphasizes the importance of good communications and teamwork skills in a successful engineering environment. Provides practice in problem solving and design. Discipline specific projects with an emphasis hands-on experiments and projects. • Prerequisites: This is the introductory course in engineering, no prerequisites. • Textbook: Handouts in each separate section of CEE, ECE, and ME • Instructors: Civil and Environmental Engineering – Graduate TA’s • Electrical and Computer Engineering – Dr. John Helferty • Mechanical Engineering – Dr. ShririamPillapakkam

  4. Syllabus and Course Outline • Course Learning Objectives: • Successful completion of this course will enable the student to: • Understand the general areas of study and practice associated with the Civil and Environmental, Electrical and Computer, and Mechanical engineering disciplines.(PO b) • Understand the importance of developing good communication and teamwork skills in a successful engineering career. (PO f) • Understand the basics of the design process. (PO b) • Understand the basic approaches to problem solving. (PO b)

  5. Syllabus and Course Outline • Course Topics • Civil and Environmental Engineering – Graduate TA’s • MATLAB: applications basic engineering analysis to (CLO 1-4) • Electrical and Computer Engineering – Dr. John Helferty • Arduino microprocessors, servo motor control, sensing using photoresistors and ultrasonics, and wireless communications. (CLO 1-4) • Mechanical Engineering – Dr. Pillapakkam • Solidworks in CAD/CAM software, 3D printing, basics of machining (CLO 1-4) • Grading • Each of the above section in CEE, ECE, and ME will carry a weight of 20% each for a total of 60% • Hovercraft Design and final competition 30% • Dr. Baren technical communications 10%

  6. Breakout Groups • Take 150 students and divide them into 3 sections. • Each section attends one of the 3 components for 3 weeks. • Rotation is done for two cycles, that is each section will attend each component twice • Last two weeks are completing the hovercraft

  7. Group Allocation

  8. ECE COMPONENT • The Arduino Processor, Robots and Gadgets

  9. What is a micro-controller? (The Arduino Uno) • A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. • The Arduino Uno is a microcontroller board based on the ATmega328 . • The Arduino Uno is a special micro controller which has all of its I/O pins mapped out for connecting various kind out of sensors and other I/O pheraphial devices. This I/O pins can be controlled directly by providing programming instruction in the Arduino IDE called a sketch.

  10. How is it Implemented (The connection between the hardware and software) • All the sensors are connected to the digital I/O pins of the Arduino Uno Microcontroller . • Once the Hardware is connected (the sensors and the motors) to the board, the software is written on the Arduino IDE in a file called Sketch. The sketch are similar to C++ programming language, but are linked to various precompiled functions that takes care of lot of behind the scene hardware programming involved . • Once the desired Sketch is written, the Sketch is uploaded to the flash memory of the Arduino Uno’s flash memory via a USB cable.

  11. How does the Robot work? • The Arduino Uno based robot is based on the concept of digital feedback control network . • A feedback control network takes in information from the sensors and goes through a algorithmic decision making process, that drives the Robot . • In this case we use a ping ultrasonic sensor that makes a measurement of distance to the left, right and in front of the robot. • After making the measurements, the microprocessor compares all the values and makes a decision of going in the direction of the maximum distance.

  12. The ECE Plan: First 2 weeks • Week 1: Introduction to the Arduino Integrated Development Environment • Equipment Used: Arduino Microcontroller and desktop computer • Theory: • Programming instruction set and the integrated development environment, I/O ports • Experiments • Writing code to make blinking LED’s in different sequences • ____________________________________________________________ • Week 2: Introduction open -loop motion control • Equipment Used: Arduino Microcontroller, desktop computer, assorted electronic parts, servo motors, chassis, etc. • Theory: • Introduction to pulse-width modulation control of servo motors, open loop control • Experiments: • Open loop motion control of traversing paths in the form of simple geometric objects

  13. The ECE Plan: Last 2 weeks • Week 3: Closed-loop control using photoresistors and line following • Equipment Used: Arduino Microcontroller , photoresistors • Theory: • Operation of photoresistors, line following using photoresistors as a feedback sensor • Experiments: • Multiple line following exercises • ______________________________________________________________ • Week 4: Ultrasonic obstacle detection and avoidance • Equipment Used: Arduino Microcontroller , ultrasonic sensors • Theory: • Generation of ultrasonic pulses, obstacle detection. • Experiments: • Simple maze navigation techniques. • Extra Credit: WiFi communications between the keyboard and controlling the Arduino robot.
