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.
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).
The language was originally conceived to teach concepts of programming related to Lisp and only later to enable what Papert called "body-syntonic reasoning" where students could understand (and predict and reason about) the turtle's motion by imagining what they would do if they were the turtle.
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]
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.
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.
COMAL was created as a mixture of the prevalent educational programming languages of the time, BASIC, Pascal, and, at least in the Commodore and Compis versions, the turtle graphics of Logo. The language was meant to introduce structured programming elements in an environment where BASIC would normally be used.
