Automatic writing machine

Abstract

The invention discloses an automatic writing machine. The automatic writing machine comprises supporting bases, stepping motors, a motion supporting frame, an X-axis movement mechanism, a Y-axis movement mechanism, a synchronous pulley transmission mechanism, a penholder rising and falling mechanism, a CNC Shield expansion board and a conversion module based on an existing speech recognition technology. The synchronous pulley transmission mechanism can achieve planar movement of the penholder rising and falling mechanism through control by the stepping motors. The penholder rising and fallingmechanism can achieve pen lifting and falling of a penholder through control by a steering engine. According to the automatic writing machine, the conversion module based on the existing speech recognition technology is adopted, speech signals are converted into G codes, the converted G codes are turned into motor control instructions on all the mechanisms through compiling by the CNC Shield expansion board, and therefore the X-axis movement mechanism, the Y-axis movement mechanism and the penholder rising and falling mechanism can be driven to do repeated writing work according to the set G codes, working efficiency is improved, and writing by the blind through speeches is made possible.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic writing machine. Background technique [0002] Text is an important medium for the continuation of human civilization. Now with printers and copiers, the efficiency of text recording has greatly increased. However, the printed and copied text materials use inkjet methods, which have obvious machine characteristics, and are completed with pencils, pens or ballpoint pens. There are significant differences in the written materials. In some occasions where pencils, pens or ballpoint pens are required to write, it mainly relies on manual copying, which is labor-intensive. [0003] In addition, although there are blind writing tablets tailored for blind people on the market, they are limited to blind people communicating with blind people. Since not all blind people can write, in the prior art, such blind people need to communicate with normal people through text. It is ...
