A general-purpose language, Logo is widely known for its use of turtle graphics, in which commands for movement and drawing produced line or vector graphics, either on screen or with a small robot termed a turtle. The language was conceived to teach concepts of programming related to Lisp and only later to enable what Papert called "body ...
Turtle graphics are often associated with the Logo programming language. [2] Seymour Papert added support for turtle graphics to Logo in the late 1960s to support his version of the turtle robot, a simple robot controlled from the user's workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robot's body.
MicroWorlds is a family of computer programs developed by Logo Computer Systems Inc. (LCSI) that uses the Logo programming language and a turtle-shaped object to teach language, mathematics, programming, and robotics concepts in primary and secondary education.
MSWLogo is a programming language which is interpreted, based on the computer language Logo, with a graphical user interface (GUI) front end. George Mills developed it at the Massachusetts Institute of Technology (MIT).
In modern implementations, an abstract drawing device, called the turtle, is used to make programming for children very attractive by concentrating on doing turtle graphics. Seymour Papert , one of the creators of Logo, was a prominent figure in constructionism , a variety of constructivist learning theories .
Small Basic includes a "Turtle" graphics library that borrows from the Logo family of programming languages. For example, to draw a square using the turtle, the turtle is moved forward by a given number of pixels and rotated 90 degrees in a given direction. This action is then repeated four times to draw the four sides of the square.
NetLogo was designed by Uri Wilensky, in the spirit of the programming language Logo, to be "low threshold and no ceiling".It teaches programming concepts using agents in the form of turtles, patches, links and the observer. [2]
Simple GIF animations may also be produced with the GIFSAVE command. Jim Muller wrote The Great Logo Adventure, a complete Logo manual using MSWLogo as the demonstration language. FMSLogo evolved from MSWLogo: An Educational Programming Environment, a free, open source implementation of the Logo programming language for Microsoft Windows. It is ...
