This paper studies the structure and development of the robotics market in Spain. The robotisation process of Spanish industry began in the bigger firms, but nowadays small and medium sized firms are the main adopters of robots. The degree of concentration of demand has decreased more than that of supply. The participation of robots in Spanish technology is still small although half the robots adopted are manufactured in Spain. The development of supply has been endogenous, but supplier firms share robots with other equipment in their product portfolio.
