What is a Robot?

What is An Intelligent 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

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– Artificial Intelligence
