Abstract: An apparatus and method for planning a drilling sequence. The solution relates also to a rock drilling rig and to a computer program product. The apparatus searches several possible drilling scenarios for drilling a given drilling pattern. Different actions required by the scenarios have given costs and the executed algorithm calculates total costs of found scenarios. Scenarios with the lowest costs are selected.

Abstract: A method for initiating a remote operation mode of a work machine, the method including providing the work machine with a work machine-specific safety key; receiving, at a remote control station, a notification from the work machine in response to initiating the remote operation mode of the work machine by said safety key; acknowledging the work machine as being included in a safety system of the remote control station; and configuring the remote control station to start the remote operation mode of the work machine.

Abstract: A method for controlling an automated drilling process on a work machine includes the steps of obtaining, from at least one input, data determining operations of the work machine; generating reference data based on the data determining previous operations of the work machine in substantially the same area; detecting a region of interest in the reference data; and controlling, in response to the work machine or its drilling process approaching a point corresponding to the region of interest in the reference data, the work machine to provide an operator with an option to manually assist the operations of the work machine at the point.

Abstract: A method and control apparatus for controlling more than one rock drilling rig operating on the same working site, and a rock drilling rig. A master unit controls the drilling by the rock drilling rigs via a wireless network and sends the rig the necessary information about the drilling plan of the working site.
