Turtle Graphics, Robotics

Turtle Graphics

What is it?

A method of programming specifically designed for children to do some basic programming

A method of programming

By controlling the movement of the ‘turtle’ on the screen by typing key instruction for it to move

What does it affect in everyday life?

It is used to carry out drawing functions for Programming the graphics by drawing.

What’s the profit and lost when using it?

Application using sensor

What does it affect in everyday life?

Monitoring: Burglar alarm system

fingerprint-based attendance management system

Record in the data will be accurate and more secure (updates the data overnight)

 Controlling:  Greenhouse Environment

                        To control its environment.

What’s the profit and lost?

Monitoring   : Lost: Expensive, May break down, easily set or hacked and can cause problems

Profit: Efficient, Accurate, Can be taken more frequent, Updates automatically, and keeps data safe

Controlling   : Profit: Safer, Direct response, Accurate

How does the sensor affect the control?

Monitoring: collects data and updates the files or data. It will give notice but does not result changes.

Controlling: reviews the data from the sensors. It will give notice and automatically changes the process

Sensor Lens or Light, how does it work?

Light:  image control street light control: it computes the amount of vehicles in a street. If there’s snow on the street, it will be dimmer because ice can reflect the light.

Photocells: light can be controlled by photocells. These are light-sensitive sensors that responds to the amount of light detected.

Example : Washing Machine

It has the sensor to detect how much time is needed to dry the clothes

 Robotics

Robotics is a computer science

One of the ways ICT is used.

It is used in manufacturing

The profit and lost when it uses ICT

Profit : Efficient, doesn’t need wages, Higher productivity, don’t have any feelings, Can work in a harmful environment

Lost    : Difficult to do ‘unusual task’, Replace skilled labour, risk of de-skilling, Factories can be moved, Causing unemployment
