The IFR Statistical Department, hosted by VDMA Robotics and Automation in Frankfurt, has published its 2007 World Robotics survey. The survey comprises statistics, market analysis, prognoses and case studies. After the record numbers recorded in 2005, sales of industrial robots were 11% lower in 2006, at 112,200 units. Nevertheless, this was the second highest result ever recorded. Although the automotive and the electrical/electronics industries, which in 2005 were still the main engines of the rapid growth that had been experienced, reduced their investment in robotics by 17% and 34% respectively, all other industrial sectors increased robot purchases by 25%.
Worldwide there are now over 951,000 robots in operation. Almost 50% of these are in Asia, a third in Europe, and 16% in North America.
Up to the end of 2006 about 40,000 service robots for professional use were installed worldwide. With more than 9,000 units the service robots in defense, rescue and security applications accounted for the highest share of the total number of service robots for professional use installed up to the end of 2006.
The unmanned aerial and ground-based vehicles for military use are the most established professional robots. Thereafter follow milking robots, underwater systems, pool cleaning robots, demolition systems for the construction industry, robot assisted surgery and mobile platform for general use.
Turning to the projections for the period 2007-2010, the stock of service robots for professional use is forecast to increase by some 35,500 units. Application areas with strong growth are military applications, field robots, cleaning robots, medical robots and mobile robot platforms for multiple use.
About 3.5 million service robots for personnel/domestic use were sold up to 2006. So far, service robots for personal and domestic use are mainly in the areas of domestic (household) robots, which include vacuum cleaning and lawn-mowing robots, and entertainment and leisure robots, including toy robots, hobby systems and education and training robots.
Robots for handicap assistance have not yet taken off as could be expected given their potential in regard to both the supposable need and the existing technological level of the equipment. In a longer perspective, say in the next 10 years, and taking into account demographic shifts and advances in technology, assistive robots for disabled and handicapped persons are certain to be a key area for service robots.
