All-purpose robots are not, of course, a new vision. "It's been 5 or 10 years from happening for about 50 years," says Eric Berger, co-director of the program.
I'm not clear about what the sentence underlined means. What has been 5 or 10 years, the vision of all-purpose robots?
What has been happening for 50 years, the vision of robots?
