Abstract:

One important aspects in the evolution human is the use of tools that simplify the physical work. Robots also fall into this category, but they occupy a privileged position due to their complexity. Humans imagined intelligent mechanized devices that would take over a significant part of the physical effort. Thus its has built automatic devices and intelligent mechanisms or different robots.Robots are automatic electromechanical machines. Some of the robots are not fully automatic but are controlled by humans by remote control, using video cameras or other control systems. Most robots are used in manufacturing processes. Others can be used as remote-controlled, deep-sea manipulators. Another category of robots can be used in various laboratories where they work with radioactive substances or there are high temperatures or other dangerous places. Some robots are mobile, with a built-in locomotion system, being able to move on land, on water, in the air. The modes of propulsion are among the most diverse, such as on wheels, water, water jet or air etc.In this paper, one tried to present a simulation of an educational mobile robot, imposing a rather complex wiring diagram, a command and control of the robot made by a PIC16F84A microcontroller. This robot can be used in teaching activities, but also in surveillance tasks, monitoring of spaces difficult for humans to penetrate.
