One of the biggest high-tech disappointments of the decade has been the failure of the market for robots to take off as forecast, but things are looking a little brighter: GMFanuc Robotics Inc, equally owned by General Motors Corp and Fanuc Ltd, says it expects to return to profits this year on a sales increase of between 15% and 20%; last year, sales slumped 54% to $102m, and the company made a loss of a few million dollars; it now sees profits of several million.
