What is a Robot? An autonomous system which exists in the physical world, can sense its environment, and can act on it to achieve some goals.

Spectrum of Self-Control Teleoperation: Human Control Shared Human – Robot Control Autonomous (AI) Control

Living Autonomously An autonomous robot acts on its own decisions Robots are not directly controlled by humans –Can take input and advice from humans Robots are not teleoperated –Making them much more difficult and interesting than BattlebotsBattlebots

Autonomous Mobile Robots have to Solve Difficult Problems Where am I? –Localization Problem How do I get there? –Path Finding Problem How do I find the door? –Object Recognition Problem What are you asking me to do? –Language Understanding Problem How can I tell you the answer to your question? –Speech Generation Problem

Existing in the Physical World Inaccessible –near by stimuli, limited attention, imperfect sensors Non-deterministic –Complex set of laws (many unknown) Dynamic –Changes happening as decisions are made Continuous –The worlds is not a set of discrete events

Sensing the Environment Sensors allow the robot to perceive its environment to get information that allows it to make decisions –Humans have 6 senses what are they? –What sensors does a robot need? Movie Clip

Acting on the Environment Robots have effectors that allow it to change the state of the world –What are human effectors? –What effectors can robots have? Movie Clip

Achieving a Goal Achieving a goal requires intelligent decision making –Artificial Intelligence MovieMovie Clip

Robots are complex systems So, what makes a complex systems complex?

Interactions Between Sub-systems Complex systems consist of multiple sub-systems, each one has the potential of interacting with every other one.

Complexity comes from Multidisciplinary Systems Complex systems can be an integration of mechanical, electrical, chemical, and computational sub-systems. Like vacuum cleaners, washers, cars, hard drives, space shuttles, …

and robots.

Why study Robotics? Well, robots are way coooool! Other areas that deal with complex systems share the same principles involved in designing and implementing robots

Why Study Robotics? Real-time Systems

Why Study Robotics? Multitasking

Why Study Robotics? Integrated Systems Engineering –Mechanical Engineering –Electrical Engineering –Computer Science –Chemical Engineering –BiologicalBiological Continental's electronic stability system analyzes data from many sensors. When the sensors indicate a driver is losing control, the system steadies the vehicle by braking one or more wheels or by slowing down the engine.

The Top 10 Reasons for Taking This Course 10: I want to play with LEGO’s for a grade! 9: All the other CS/ME/ECE/IME electives are lame. 8: Class is taught by the best teachers in the School of Engineering. 7: The Transformers movie ruled, dude! 6. I can use the pick-up line “Want to come see my robot?”

The Top 10 Reasons for Taking This Course 5: So I can invent a robot that looks like me and I’ll never have to go to another class. 4: I can put on my resume: “Robot Builder”. 3: Lots of cool pics, demos, & videos. 2: I want to take over the world!I want to take over the world! 1: Robots are way cooooool! Peace out …

ROBOTICS

And The Categories Are….. Planning Integration Communication Navigation Sensors ControlMechanisms Signal Processing Robots

Robots for $2.00 The answer is …. Robots are built by these. And the question is… What is a cross-functional or multidisciplinary team?

A Multidisciplinary Robotics Course Co-taught course: –Dr. Engel, Electrical & Computer Engineering –Dr.Krauss, Mechanical Engineering –Dr. Karacal, Industrial & Manufacturing Engineering –Dr. Weinberg, Computer Science

Course Objectives 1.To learn to work in a multidisciplinary team. 2.To provide a hands-on experience to practical robotics. 3.To learn about integrated system design. 4.To study the mechanical mechanisms necessary for robot movement and actions. 5.To study the electrical mechanisms of sensor sampling and signal processing. 6.To study the computational mechanisms necessary for sensory perception. 7.To study the computational mechanisms of autonomous robotics.

Readings Textbook: –Robotic Exploration by Fred Martin –Introduction to AI Robotics by R. Murphy –Additional reading will be assigned. IMPORTANT: RIF –Teaching a multi-disciplinary course is challenging

Designing, Building & Programming Each class member will participate on a cross functional team of 3 or 4 students from different disciplines. Teams will work on a variety of lab assignments that include designing & building mechanisms, circuits, and robots Robot will be built using the XBC, iCreate, and IC ( ).

Final Project Multidisciplinary Teams will design and build a robot to complete in a Urban Search and Rescue Challenge Builds upon lab assignments
