Control – explained


1. Control
This is when a person is controlling the machines that are working. For example, a crane, it needs someone to control what it is doing and picking up.

2. Robotics
This is when machines become fully autonomous and do not need a person controlling what they do, only someone to type in a work sequence for them. Also they require a technician for the robots. For example, a robot in a car factory, the robot puts the dashboard in automatically when the car rolls up to its station.

3. Cost benefits
You need fewer people working hands on with the cars, because there are fewer manual tasks to do, so this saves the company money. Also more technical staff have been employed, but much less than the workers. Also the robots can be made to work for a really long time compared to workers, so in the long run all these things combined saves the company money, which increases profit.

4. Basic commands
You can shorten the commands you enter: Right – rt. Left – lt. Forward – fd. Backwards – bk. Penup – pu. Pendown – pd.
a. Angles
If you would like the turtle to move at a certain angle then you need to enter the direction you would like to turn into e.g. Right or Left. Then you specify the angle degree you would like e.g. 45 or 90. Then you enter them together, Right 90. You can shorten it to, rt 90.

b. Distance
For the distance you can have either go forward or backwards on the angle you have chosen. Once your turtle is on the angle you wish, make sure your pen is down, then type in forward/fd or backward/bk (the number for the distance you wish). E.g. fd 100.

c. Shapes
The turtle is able to draw shapes too. All you need is a certain procedure, e.g. for a square you would enter, fd 100 rt 90 fd 100 rt 90 fd 100 rt 90 fd 100. Or use repeats, repeat 4(fd 100 rt 90).

5. Repeats
Instead of typing out long procedures you are able to repeat the commands. For example, a square, fd 100 rt 90 fd 100 rt 90 fd 100 rt 90 fd 100 = repeat 4(fd 100 rt 90).

6. Stored procedures
You are able to store all commands in a specific word. For e.g. if you want to store a square, you type in “to square”, and then you put in the command for a square. So then if you type in “square” it draws a square for you.

1. Lighthouse
You can create a lighthouse where you have three main functions, the top light, the lights in the lighthouse body, and the sun. When the sun is out both lights in the light house are off. When the sun is out then the two lights in the lighthouse turn on. This is done automatically.

2. Traffic lights
There are two traffic lights which are on opposite sides of the bridge. They both start at red, then one starts yellow up and then turns green, then after a while it turns back to red and then the other side starts this procedure.

Real world control systems


1. TVs & similar systems
TV’s use remote controls which allow the TV to do certain functions. The remotes have commands programmed into each button so when pressed, the TV knows what it must do.

2. Factory systems
Factories use robots to do functions, the robots have the commands programmed into them so when it comes to building something, the robot knows what to do automatically.
