Robot abacus refers to the use of robots in arithmetic operations such as addition, subtraction, multiplication and division. Robot abacus refers to the use of robots in arithmetic operations such as addition, subtraction, multiplication and division. It involves the process of data input, processing and output, as well as calculation and control according to the algorithm. The expression "abacus" is not accurate and has gradually become obsolete. The common saying now is that "robots do mathematical operations". In many fields, including but not limited to manufacturing and service industries, people will use robots to complete various complex tasks, including performing complex mathematical operations to achieve accurate control and measurement. These robots can be equipped with special hardware devices (such as sensors) to collect and process data, and have strong programming ability to realize specific arithmetic functions.
