Another important aspect of the control unit is the different operating modes of the computer. Computers alone are not enough to effectively control a robot. The simpler the commands are, the more complex it is for the robot to interpret them. Objective languages resemble our naturally spoken sentences. High levels of artificial intelligence and voice recognition ability are necessary.
Commercial languages are practical robot languages and simpler than high level ones.
Assembly and machine languages are used to write instructions directly for each MPU operation. The last components to be discussed are the sensors . These are microelectronic devices that can monitor changes in the surrounding environment. They can respond to a variety of phenomena, such as pressure, temperature, and the presence of physical objects. The simplest form of touch sensing is the mechanical switch.
