Between the launch of Sputnik on 4 October 1957 and 1 January 2008, approximately 4600 launches have placed some 6000 satellites into orbit, of which about 400 are traveling beyond geostationary orbit or on interplanetary trajectories. Today, it is estimated that only 800 satellites are operational. 70% of all catalogued objects are in low-Earth orbit, which extends to 2000 km above the Earth's surface. The geostationary ring, at an altitude of about 36,000 km. This orbit is heavily used by telecommunication satellites. Space debris comprise the ever-increasing amount of inactive space hardware in orbit around the Earth as well as fragments of spacecraft that have broken up, exploded or otherwise become abandoned, ranging in size from as big as an automobile to microscopic dust.
The debris objects shown in the images are an artist's impression based on actual density data. However, the debris objects are shown at an eggagerated size to make them visible at the scale shown. More information can be found on the website of the European space agency (ESA).

There are now 1 million industrial robots toiling around the world, and Japan is where they’re the thickest on the ground. It has 295 of these electromechanical marvels for every 10 000 manufacturing workers—a robot density almost 10 times the world average and nearly twice that of Singapore (169), South Korea (164), and Germany (163).

Although the top three countries are in Asia, Europe gets the regional title as the epicenter of global automation; it has a robot density of 50, compared to 31 in the Americas and 27 in the Asia/Pacific region (data from ieee spectrum online). More robo-statistic you can find here.
