This report will cover the work involved in building a quadruped robot which should to a certain extent resemeble a four-legged mammal. The introduction will present information related to what has inspired the project, purpose/aim, specifications, limitations and research questions. Most important in the introduction are probably the purpose/aim and research questions. Mainly, the goal was to have the robot be able to self-balance and later also be able to walk to some degree if possible. The first research question concerns how well a PID controller would affect the stability of the robot and the second question is about answering if referencing a fourlegged mammal is a good idea when building a quadruped robot. Theory and methods were combined and written as one chapter. This way relevant information could be provided in the appropriate places as the method for creating the robot was described. The chapter dives into the primary parts of the robot which are the choice of components, construction, inverse kinematics and last but not least the code including the implementation of a PID. The results show that PID regulation improves stability and performance, but PI regulation actually performed the best. Furthermore, the question regarding referencing a four-legged mammal remains inconclusive even though the model was sufficient for the task.
