Introduction to robotics

  1. 1. INTRODUCTION TO ROBOTICS-Lecture 1 Pantech Prolabs India Pvt Ltd
  2. 2. What is robotics?  Robot: a machine with a physical embodiment that produces actuation based on its sensory information  sensing, actuation, control  A simple robot: a thermostat, 1DOF robot  Examples : ActivMedia PioneerRaibert hopper
  3. 3. Robots, machines, and agents  Embodiment  a robot’s embodiment is its medium to interact (sensing and actuation) with its environment  embodiment constrains a robot  Situatedness  robots are strongly affected by the environment and deal with its immediate demands directly  Situated intelligence  observed behavior resulting from interaction between a robot and its environment  cannot be attributed to a single source, model, or rationale © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  4. 4. Robots, machines, and agents  Autonomy a robot is a machine with autonomy robots are motivated to achieve some goal  Uncertainty an inherent property of the real world Physical sensors and actuators provide limited, noisy, and inaccurate information and force generation The certainty of physical sensors and effectors cannot be well characterized © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  5. 5. Applications for robotic technology  Industrial/assembly/inspection  Search and rescue  Hazardous operation (demining, defusing, chemical)  Medical Applications  Entertainment  Space and underwater exploration and development  Assistive/rehabilitation  Education  Transportation  Ecology, geosciences © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  6. 6. Basic roadmap of robotics  Engineering robotics: constructing physical embodiment and physical dynamics mechanical engineering  Control theory/ Signal processing  Autonomous control  Learning/Adaptation © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  7. 7. Basic roadmap of robotics  Engineering robotics:  Control theory/ Signal processing producing appropriate control signals interpreting/processing the world from sensory data mechanical and electrical engineering  Autonomous control  Learning/Adaptation © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  8. 8. Basic roadmap of robotics  Engineering robotics:  Control theory/ Signal processing  Autonomous control programs for producing control signals from sensory data computer science and electrical engineering  Learning/Adaptation © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  9. 9. Basic roadmap of robotics  Engineering robotics:  Control theory/ Signal processing  Autonomous control  Learning/Adaptation extending the robot’s autonomy beyond what is explicitly programmed © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  10. 10. History of robotics  The term “robot” was popularized by Czech playwright Karel Capek,combining “rabota” meaning “obligatory work” “robotnik” meaning “serf”  Traditional notions of robots clever mechanical devices or automatons  Advancement in computation has redefined these notions © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  11. 11. Grey Walter’s Tortoise  Acknowledged as the first robot (1953)  Inspired by cybernetics  Exhibited emergent behavior from reactive control © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  12. 12. Shakey  One of the first AI-inspired robots  mobile robot with contact and camera sensors  Lived in a specially constructed world  Shakey name derived from how it executed it plans © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
  13. 13. Other early AI-inspired robots  HILARE  Moravec’s CART/Rover © 2008 Pantech Solutions™ | All rights reserved | www.panetchsolutions.net
