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.
The first working Logo turtle robot was created in 1969. A display turtle preceded the physical floor turtle. Modern Logo has not changed very much from the basic concepts predating the first turtle. The first turtle was a tethered floor roamer, not radio-controlled or wireless. At BBN Paul Wexelblat developed a turtle named Irving that had ...
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
MSW Logo windows. 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).
This 15- to 30-foot space also allows the pedestrian to safely enter the crosswalk and have vision on the second lane of traffic to ensure the vehicle in that lane can see them and yield as well.
Turtle robots are commercially available and are common projects for robotics hobbyists. Turtle robots are closely associated with the work of Seymour Papert and the common use of the Logo programming language in computer education of the 1980s. Turtles specifically designed for use with Logo systems often come with pen mechanisms allowing the ...
A zebra crossing (British English) or a marked crosswalk (American English) is a pedestrian crossing marked with white stripes (zebra markings). [1] Normally, pedestrians are afforded precedence over vehicular traffic , although the significance of the markings may vary by jurisdiction.
The marker interface pattern is a design pattern in computer science, used with languages that provide run-time type information about objects.It provides a means to associate metadata with a class where the language does not have explicit support for such metadata.
