robot
by Graham Betts - Thursday, 18 August 2005, 04:15 PM
 A robot is a machine which can be programmed to perform tasks and which will be able to adjust to its environment through use of sensors
Keyword(s):
Autonomous
by Graham Betts - Thursday, 18 August 2005, 04:35 PM
 Operating without pre-programmed behaviors and  without supervision from humans. These robots will probably be programmed using languages like LISP or PROLOG

Industrial Robots
by Graham Betts - Friday, 19 August 2005, 11:12 AM
 

Industrial robots are robots that are used in industry; normally on production lines. They normally fixed bases around which the arms will move by use of actuators.

Actuator
by Graham Betts - Friday, 19 August 2005, 07:53 AM
 A device which performs the physical movement of a robot. 3 types electric hydraulic and pneumatic.

Electric Actuator
by Graham Betts - Friday, 19 August 2005, 07:56 AM
 Electric actuators are simply electro-mechanical devices which allow movement through the use of an alectrically controlled systems of gears. Some common types are stepper motors, solenoids and an electric motor. Electric motors are the most common form of actuator.
Keyword(s):
Analogue
by Graham Betts - Saturday, 20 August 2005, 10:52 AM
 Data from the natural world which will have an infinite number of variables. For example sound from the natural world will have an infinite number of possible variations
Keyword(s):
Solenoid
by Graham Betts - Saturday, 20 August 2005, 10:55 AM
 A solenoid is simply a bit of wire wrapped around a magnet which produces a magnetic field when electric current is passed through it. Depending on the direction movement of the electrical current, which depends on which side the positive and ngative terminals are connected, will decide which sides have the north or south poles and so force movement through repelling or attracting.
Keyword(s):
Pneumatic Actuator
by Graham Betts - Saturday, 20 August 2005, 10:55 AM
 Pneumatic actuators use compressed gas to force the movement of pistons through the use of pumps and valves and so allow movement of the robotic part. Pneumatic actuators work on the same principles as hydraulic actuators using a series of valves, pumps and pistons to gnerate movement in the robot.
Keyword(s):
Stepper Motor
by Graham Betts - Saturday, 20 August 2005, 10:55 AM
 Stepper Motors are also called step motors and allow small precise movements. Stpper motors are electrical motors that move a series of small gears fixed increments each turn (step) of the motor. These are typically used in printers and scanners to move the heads. Not appropriate for heavy loads.
Keyword(s):
Hydraulic Actuator
by Graham Betts - Saturday, 20 August 2005, 10:55 AM
 Hydraulic actuators allow a robot to move by the use of fluids moving under pressure through a series of valves by the use of pumps. The hydraulic fluids bused would normally consist of oils which are reasonably non-compressible. They are used where a lot of power is needed to move things. These would commonly be industrial robots possibly used on a car assembly line.
Keyword(s):
Domestic Robots
by Graham Betts - Sunday, 21 August 2005, 08:24 AM
 

Domestic robots are robots that are designed for use around the home (domestic). Examples of these already in production are robot vacuum cleaners and robot lawn mowers. Household robots are starting to take off, Farewell lawnmower... hello robot., Fledgling robot industry aims to fly high, Home invasion fuels robot explosion.

Relay
by Graham Betts - Saturday, 20 August 2005, 11:12 AM
 A relay is an electromechanical switch that uses an electromagnet to open or close one or many sets of contacts. In other words iut turns things on or off. When the relay is activated an electromagnet is turned on which will turn the relay switch on. A relays normal position may be on. In this case an electro magnet would actually turn the swict off.
Keyword(s):
Controller
by Graham Betts - Saturday, 20 August 2005, 11:20 AM
 A controller receives information from an input device such as a sensor and adjusts the robots actions to respond to its environment. The output from a controller will go to an actuator. The controller maybe hardware or software.
Keyword(s):
Interface
by Graham Betts - Saturday, 20 August 2005, 11:24 AM
 An interface allows the computer and peripherals to be connected and also provides the framework for humans to interact or program the robot.
Keyword(s):
Analog
by Graham Betts - Saturday, 20 August 2005, 11:29 AM
 the same thing as analogue just a different spelling (US spelling)
Keyword(s):
Separate and Connected ways of knowing
