    1. 1 159.734 Studies in Machine Learning Intelligent Robotics: an introduction Dr Christopher Messom, IIMS, Massey University, New Zealand

    2. 2

    3. 3 History Robot, first used in Karel Capek’s play Rossum’s Universal Robots made from biological parts Czech word Robota, meaning work 1921

    4. 4 History Humanoids:-Shaping public perception Metropolis (1926) Electro & Sparko (NY World’s Fair 1939) C3P0 (Start Wars, 1977) Data (Star Trek NG, 1990’s)

    5. 5 Industrial Robots:- early history Industrial Automation Spinning Jenny (1764) Cartwright’s Loom (1784) Jaquard Loom’s punched cards (1801) Ford’s production line (1920’s)

    6. 6 Industrial Robots:- late history Computer Numeric Controlled (CNC) machines Tele-operated manipulators Unimation Inc’s, industrial robot (1959) General 3-axis manipulators (1974)

    7. 7 Programming Industrial Robots Well defined environments may not need sensors if position of objects known Precise movements allows high precision work Safety Issues keep away from humans

    8. 8 Agricultural Robotics:- the New Zealand context Industrial Research Limited World leader in meat processing Projects in dairy testing and processing Forestry robotics Sustainable harvesting of trees

    9. 9 Motivation for Automating Meat Processing Quality control Health & safety of workers Big issue especially in developed countries Contamination of food products Litigation issues

    10. 10 Pelting and Y cut robots Y Cut:- skilled operation Highly variable inputs Failure modes avoided to reduce wastage Episodic operation Pelting:- labour intensive

    11. 11 Robotic System Design Sensor System inputs, vision, distance, angle etc Actuator System outputs, power to motors, joints etc Control System process, calculation of required outputs Intelligence is in the Control System

    12. 12 Robot Control Example 1

    13. 13 Pole Balancing Robot Inputs Angle and Distance Outputs Motor speed Control System Implemented Using Fuzzy Logic Control

    14. 14 Robot Control Example 2

    15. 15 Robot Soccer Robots Inputs Vision system and wheel velocities Outputs Motor power Control System Combination of Artificial Intelligence Techniques Machine Vision & Multi-Agent Systems Classical Control

    16. 16 Entertainment Robotics Educational toys Lego’s programmable bricks Mindstorm etc Robot companions Sony Aibo Tiger Electronics I-Cybie Animatronics Babe the movie etc.

    17. 17 Programming Entertainment Robotics Unpredictable environment robot’s often interact with people Challenges of Intelligence Robots machines that think machines that learn machines that emulate human behaviour Anthropomorphic Robots character, emotion, humour

    18. 18 Virtual Robotics Simulation of Robot Industrial Entertainment Humanoid Allows research ideas to be tested in a cost effective manner Systems dynamics modelled mathematically Visualisation using VRML & Java3D

    19. 19 Review Questions What is the origin of the term robot ? What were the main influences that formed the public perception of robots being humanoid ? Identify the main differences between the current state of the art in industrial robots and entertainment robotics.

    20. 20 Review Questions What is the role of virtual robotics in robotic research ? What do we mean by Intelligent Robots? In which field of robotics does New Zealand have a technological lead ?

    21. 21 Conclusions Robotics spans industry, business & the home Many research topics still to be explored General Intelligent Robots are still a dream Finally thanks for your attention
