1 Rockets, Robots, Hovercraft, and Quadracopters, all for the STEM of IT! John J. Helferty Temple University

2 OUTLINE Student Space Exploration and Embedded Systems Lab Recent History of Projects New Introduction to ENGR-1101 RockSat-C Lunabots Quadracopter competitions

3 Recent History Lab created in 2009 to support UG/G student driven projects. Faculty mentors act as advisors, students drive the projects Fully equipped with drill presses, band saws, scopes, meters, etc.. Each year approximately 30 students are involved

4 RockSat Projects Since 2009 there were 4 successful RockSat-C Launches 2009 Workshop 2010 Passive Vibration Suppression payloads, Active Vibration Suppression and magnetic field studies 2012 Biological sampling at different altitudes 2013 CO2 measurements at different altitudes

5 Lunabots Participated since inception in wheels and conveyer treads and front end loader (successful but slow) wheels with ribs, loader, autonomous (moved to fast) treads, autonomous (we shall see)

6 Augmentation Grant for New Course ENGR-1101 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.

8 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%

9 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

11 ECE COMPONENT The Arduino Processor, Robots and Gadgets

12 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.

13 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.

14 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.
