【 摘 要 】

The author of this paper joined Atlas Copco in 1975. Atlas had already then a project going since late 60ies for automatic positioning of Drill Jumbos. This was before the micro processor (The first was the 4 bit Intel as some may recall, which came around 75) Instead the mathematical functions for calculating positions (wanted and actual) were done “hard wired” using ECL logics. The project team consisted of ex. Bofors anti-aircraft gun control system designers. Maybe we will never see a faster system, but the flexibility of this system left everything to wish for and the size and power consumption was of course a concern. (Each boom used a box 600x 600 x 1000 mm, filled with electronic pc cards) Change of drill pattern; drift size etc. meant changing of cards or adjusting a number of switches. As soon as the potential of the programmable micro processors became obvious, new drill rig automation projects were started. I t was still a difficult task, and not until 1986 could we introduce a commercial rig in Las Vegas . A 2 boom fully automatic drill jumbo named the Robot Boomer. All this is maybe history without value but for those who participated, but of relevance, is to discuss the reasons for this automation and the suggested benefits for the customer.[first paragraph]
