Robot brains come in a wide variety of forms. In fact, some robots are built without brains and are controlled by people through remote control. Robots can also be built with a brain that is spread out in different parts of the robot. For instance, basic chips can be used to operate individual parts of the robot, such as an arm or leg, with these individual parts working independently of the other parts. Furthermore, robots can be built with brains that are located far away from its body, such as in a computer.
All things considered, the number one choice for robot brains is the microcontroller chip. Like the microprocessor chips found in computers, microcontrollers are similar, except that microcontroller chips are somewhat like a tiny computer themselves. A small amount of memory and storage space is built directly into the microcontroller chip. When comparing the microprocessor chips found in computers and microcontroller chips, the chips found in computers dedicate their channels to high speed memory connectors, whereas microcontroller chips have a much larger variety of input and output ports. These ports can connect to buttons, sensors, and other devices.
Although it may not seem evident, we are surrounded by microcontrollers. These useful chips are found in vehicles, household appliances such as dishwashers, VCRs, TVs, radios, and other home and work appliances. Fortunately, the high demand for these microcontroller chips has made these chips inexpensive and abundant.
