Class 478/578: General 1 • My name is Marek Perkowski • You can call my Marek, or Dr. Perkowski or whatever you like. • This class is fun, at least for me. • I hope that you will have fun also. • We build practical robots – embedded systems • Class is graded based on practical achievements, a little bit similar to Capstone Project. • You can find all information on my webpage, find me through Google.
Class 478/578: General 2 • If you are a graduate student your project is more difficult, otherwise the same. • Two homeworks and Project • No exam. • Student presentations (related to homeworks or projects) • I expect high quality of reports (many graduate students had publications based on these reports) • Robots connected to Internet (demo and explanation next Thursday).
Class 478/578: grading • Homework 1 – 10 % (evolutionary algorithms and foraging) • Homework 2 – 10 % (any subset of your project) • Presentation – 10 % • Project – 70 % • Groups – 1 to 5 students, group leader. • In final report, each student has a separate part to demonstrate his/her work. • Each student presents a separate presentation of his work.
Class 478/578: book • Braunl. • You can find slides to this book on internet • Book was ordered early but it must be reprinted “on demand”. • If you have no book, do not worry. All is in my slides. • Somebody told me that PDF of all text is also on internet • Slides of my class on my webpage – look for “Embedded Robotics” on my main webpage. • To find my webpage do search on Google “Marek Perkowski”
Class 478/578: yourbackground • Programming • Matlab • C • C++ • Java • Some basic digital design and interfacing experience (only in some projects) • Some basic math, Boolean Algebra, probability. • Digital Signal Processing, Image Processing (for some projects, will be covered in debth in ECE 479 next quarter)
Class 478/578: yourbackground review • Boolean functions, gates and circuits • Finite State Machines • Probabilistic State Machines • Grammars • Linked Lists • Arduino
Class 478/578: yourbackground information Please give me today the following information: • Your first name, last name and contact (email, phone) • Do you want to be on my Facebook – send me message on Facebook. • Programming classes you have taken. • Programming projects you have done. • Robot projects you have done. Please write more. • Any hardware projects you have done, like fixing a radio or a computer, building a FPGA controller etc. • Your background (hardware, software, art, physics, math, biology, etc) • Are you a graduate or undergraduate student. • For each of three areas: theory, programming and practical robot building, write percentages of your project’s grade (I am not sure I will be able to take this into account in every case) • Do you prefer to work alone or in a team for this class?
