table describing or showing reality in four dimensions, a universal plotter and a scientific measurement and learning tool. The present invention relates to a sheet metal frame or blackboard with magnetic characteristics having two or three motions, which traces and represents reality in four dimensions (horizontal, vertical, depth and time) and describes reality objectively in which a t-shaped ruler is moved on a rail along the horizontal axis or x by a digital stepper motor controlled by a driver and software on the computer (horizontal motion). furthermore, a tool vehicle involving the t-shaped ruler moves along its full length (vertical movement) or y axis, driven by a digital stepper motor controlled by a controller which is in turn controlled by software on the computer, with these two movements controlled by mathematical acceleration and velocity functions. A felt tip pen or marker is placed on the tool carrier against the blackboard surface to trace all types of figures. In addition, the tool vehicle includes a third motor provided perpendicular movement to the blackboard (depth ways), along with the respective motor and its driver. Different scientific measuring tools and structures are mounted on the tool frame or vehicle and electronically connected to the different input or output pins available on the blackboard via the driver and related software on the computer, providing scientific measurement. real and laboratory instrument that interacts with the computer.
