This thesis deals with the statistical analysis of dice roll results obtained from repeated robotic throws. The aim of the thesis was to design an experimental procedure, build a throwing device, collect experimental data and subsequently evaluate them statistically. For the experiment, a robot was built using the LEGO Spike Prime kit. The robot made it possible to perform dice throws with different settings of throwing height, throwing speed and initial die orientation. For each throw, the resulting value on the die and its final resting position on the landing grid were recorded. The measured data were processed using computational scripts and evaluated by statis- tical methods suitable for categorical data. The thesis also includes the use of entropy as a measure of distribution uniformity and discusses its connection to testing deviations from the uniform distribution. The results showed that some robot settings led to partial deviations from the expected distribution, however, a general influence of any specific controlled parameter on the result of the throw was not clearly demonstrated.
