A composite number is a number that has more divisors then just 1 and itself. For example the number 6 has 4 divisors, namely: 1, 2, 3, and 6. We call these factors of the number 6. The first 10 composite numbers greater than 1 are: 4, 6, 8, 9, 10, 12, 14, 15, 16, and 18.
International Conference on Intelligent Robots and Systems (IROS) The IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) is one of the largest and most impacting robotics research conferences worldwide. Established in 1988 and held annually, IROS provides an international forum for the international robotics research community to explore the frontier of science and technology in intelligent robots and smart machines.
Infrared (IR) is an invisible radiant energy, electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (frequency 430 THz) to 1000000 nm (300 GHz) (although people can see infrared up to at least 1050 nm in experiments).
