AbstractUsing computational tools facilitating bio-inspired models has led to developing a system for characterising voice commands for controlling a prototype hexapod mobile robot’s navigation. A software subsystem was set up, as well as another mechanical and electronic subsystem. The software subsystem consisted of a prototype programme written in Java consisting of five modules (obtaining the spoken signal, extracting characteristics, comparing characteristics, defining com-mands for transmitting the mini-robot actuators using a digital gene and the control action communication module) so that the application was able to recognise isolated, predefined words in Spanish emitted by a native speaker. Commands corresponding to the mobile robot’s navigation were thus generated; such commands had to be transmitted to the respective actuators and thus an interface made with a simple electronic circuit was thus used for this purpose.
