Abstract
 
 
The objective of this thesis was to develop the digital architecture for a

small-scale drill rig intended for use by the Drillbotics team at the University

of Stavanger, for an international student competition by the same

name. The main goals of the project has been to develop a robust software

architecture, data acquisition system, data management system and graphical

user interface. The main criteria are the guidelines given by competition

organisers, criteria given in the thesis description, and criteria given by the

Drillbotics team.

We created a system for communication between the computer, programmable

logic controller and the drill rig such that we can communicate between

platforms using the CAN protocol. With this communication in place,

both the data acquisition logging and control system can operate without

delay. Any data retrieved is stored in a data management system, as per

competition guidelines. The database has been stress tested and has a 15x

safety margin between operation- and top speed, ensuring the database will

not be a bottleneck.

The main human machine interface for the drill rig, the graphical user

interface, on the computer was developed using principles researched in

advance to ensure an interface that was based on good industry practices.

The big focus on researching proper methods of making the interface is due

to the competition recently adding human machine interface as a major

judging criteria in the competition.

A system has also been developed that covers models used for steering the

directional drilling according to the industry standard minimum curvature

method. The path given by the minimum curvature method is the ideal

path that we try to follow. The path also has safety margins given to it to

ensure the rig never strays too far from the path.

The systems created in this project have had a side-goal of being scalable

and using good abstractions such that it is able to be used by future Drillbotics

teams, for both future computer science bachelor groups, or the rest

of the team as well.
