  • Why I hate Robot Wars!
  • Are robots taking over?

Science lecture

slide3

Where did the term robot originate?

R.U.R (Rossum's Universal Robots)

Karel Capek 1920

Science lecture

what is a robotic system
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

slide6

Larry – the reluctant sheep

Sweep - the robot sheep dog

Science lecture

robotic systems use different types of control
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
Robotic systems can be
  • Mechanical
  • Electro-mechanical
  • Electronic

Mechanical?

Does something useful?

Manual control?

Automatic control?

On/off or proportional control?

Science lecture

robotic systems control things
Robotic systems control things
  • When there is a tendency for things
  • to go out of control
  • When an error or change occurs

needs a closed loop system to correct errors

Science lecture

closed loop systems detect errors and correct them

Output

Feedback path

Mixer

detection

Inputs

Hot water

Cold water

Closed loop systemsdetect errors and correct them

Science lecture

slide18

Are traffic light

open loop or closed loop system?

Science lecture

slide21

Robots in space

The Beagle II project

Science lecture

slide22
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
Why I am fighting Robot Wars
  • Such programmes mis-represent robots
  • The control systems are extremely crude

Science lecture

taking control of diy robots
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

slide25

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

Science lecture

summary
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
