Slaves in the home and at work the development of robotics Science lecture
A guide to this talk • Where did the term robot originate? • What is meant by ‘robotic systems’? • What were the first robot systems? • How do we classify them? • Why I hate Robot Wars! • Are robots taking over? Science lecture
Where did the term robot originate? R.U.R (Rossum's Universal Robots) Karel Capek 1920 Science lecture
What is a robotic system? • A device that does something useful - normally done by humans or animals • A device that saves time and/or effort • A device that will go on working automatically Science lecture
Larry – the reluctant sheep Sweep - the robot sheep dog Science lecture
Robotic systems use different types of control • Manual control - a person is involved • Automatic control - no person required • On/off control • Proportional control Science lecture
Robotic systems can be • Mechanical • Electro-mechanical • Electronic Science lecture
Mechanical? Works automatically? Does something useful? Science lecture
Manual control? Automatic control? On/off or proportional control? Mechanical? Does something useful? Post mills Science lecture
Mechanical? Does something useful? Manual control? Automatic control? On/off or proportional control? Science lecture
Robotic systems control things • When there is a tendency for things • to go out of control • When an error or change occurs Science lecture
Manual control? Automatic control? On/off or proportional control? Post mills Science lecture
Manual control? Automatic control? On/off or proportional control? Science lecture
Manual control? Automatic control? On/off or proportional control? Mechanical? Electro-mechanical? Electronic? Automatic control needs a closed loop system to correct errors Science lecture
Output Feedback path Mixer Error detection Inputs Hot water Cold water Closed loop systemsdetect errors and correct them Science lecture
Post mills - what is the error detection system? Science lecture
Are traffic light open loop or closed loop system? Science lecture
A drawing of a music box designed by Leonardo da Vinci Science lecture
Automatic doors designed by Hero of Alexandria - 2000 years ago Science lecture
Robots in space The Beagle II project Science lecture
How many robots (control systems) have you got in your home?What new robot systems would you like to have in your home? Science lecture
Why I am fighting Robot Wars • Such programmes mis-represent robots • The control systems are extremely crude Science lecture
Taking control of DIY Robots • Use appropriate technology • Ensure that the materials are readily available • Use simple fastenings • Build working prototypes • Ensure that they pass the tread test • Have fun Science lecture
How can we control the robots that we will live with in the future? For the future beyond ten years ahead, science fiction is a more useful guide than forecasting Freeman Dysonhttp://www.omnimag.com/archives/interviews/dyson.html A language is needed to think about how the future might be different Raymond Williams 1961 The Long Revolution http://www.signsofthetimes.org.uk/pamphlet1/The%20Long%20Revolution.html Science lecture
Summary • Robotic systems make life easier • They have been around a long time • Manual systems rely on human control • Automatic systems have some ‘intelligence’ • We need to know what is going on so that we can influence what happens in the future Science lecture
