Shared Human – Robot Control
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.
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 Battlebots
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?

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?

Achieving a Goal
• Achieving a goal requires intelligent
decision making

What is a Robot Control Architecture?
how much of the world do we need to represent internally ?
Robot Architecture
how should we internalize the world ?
what inputs do we have ?
what outputs can we effect ?
what algorithms connect the two ?
how do we use this “internal world” effectively ?

Architectures
Robots are complex systems
So, what makes a complex system
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

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 electives are lame.
8: Class is taught by the best teachers in the School of
Engineering.
7: The Transformers movie ruled, dude!
6. Cuz this is going to be the best prom ever!
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!
1: Robots are way cooooool!
Peace out …

Readings
• Textbook:
– Robotic Exploration by Fred Martin
– Introduction to AI Robotics by R. Murphy
– Additional reading will be assigned.
Designing, Building & Programming
• Each class member will participate on a team of 3 or 4
students.
• Teams will work on a variety of lab assignments that
include designing & building mechanisms, circuits, and
robots
• Robot will be built using the XBC, IC, and Legos
(www.charmedlabs.com/ , www.botball.org).
Final Project
• Teams will design and build a robot to complete in a
Urban Search and Rescue Challenge
• Builds upon lab assignments
