Control
Control is a physical/ manual way of working machines and robots. The machines can be controlled using keyboards, touch pads, mice etc. and worked by the user.
Robotics
Robotics on the other hand are automatic and work themselves meaning that other than maintenance human interaction is rarely needed.
Cost benefits
Robots are installed in many factories around the world in this modern age as it means that despite being expensive to begin with the robots are very cost effective as they don’t need breaks (other than being shut down at night to avoid over heating) and other than maintenance costs they do not need money spent towards them like manual workers do. Money will of course need to be spent on technical staff to understand the robots and any malfunctions and to retrain original staff to be able to work in the new mechanical environment however after a short while the robots make more money than what has to be spent.

Basic commands
Turtle has very basic commands as it only really goes forward, backward, left and right (at certain angles) as well as pen up and pen down. Every time you wish to move forward/backward etc. you do not need to type the word, number and the word units you can just type the simple command of fd (forward), bk (backward), lt (left turn), rt (right turn), pu (pen up) or pd (pendown).
Angles
The angle which the turtle turns is the exterior angle of the shape you are trying to make so for example in an equilateral triangle each turn needs to be set as 120°. The angles need to be incredibly accurate in modern day factories as a slight slip can cause everything to look wrong.
Distance
The distance that the turtle moves is counted in units (e.g. forward 100 units) the distance is how far forward or backward you want the turtle to move however each unit is very small so working in hundreds is often better than single units when working on logo software however all software is different. The distance in machinery used in factories is very important as if the distance is off by even a millimetre whatever the robot is making (e.g. a car) then it can not only look bad in the finished product but ruin the whole production system.

Shapes
To create shapes you have to join each line to a turn. To create a simple pentagon the command is:
Fd 100
Rt 72
Fd 100
Rt 72
Fd 100
Rt 72
Fd 100
Rt 72
Fd 100
Rt 72


Repeats
Repeats are used to help reduce command writing as it can take a long time. A command for the pentagon command above would be repeat 5 [ fd 100 rt 72]. Repeats also help to narrow down the amount of text on screen when defining shapes and creating stored procedures.


Stored procedures

Stored procedures are created by defining several shapes with names and procedures and then linking them all together to create a full drawing.
