Abstract
The gas bottling industry is facing a number of problems. In this paper we accomplish a study on the robotic storage of oxygen gas tanks (bottles) applicable to other gases too. To do this, we developed a prototype using the Lego Mindstorms kits and we simulated the process to study the efficiency with the Petri Networks. We chose this kit, due to its complexity, being the closest to what we needed to make small scale storage. The program the robot uses for working was done in a special programming language: Mindstorms SDK and downloaded to the controller’s memory.

Summary
To study the communication with programmable machines, Carl A. A Petri net, known as a place/transition (PT) net, is one of several mathematical modeling languages for the description of distributed systems. It is a class of discrete event dynamic system. Places in a Petri net may contain a discrete number of marks called tokens. The difference between a graph and a Petri network is that in the latter case the set of nodes is replaced with two disjoint sets: 3⁄4 The set of places Pi, i = 1, ..., n (represented by circles) 3⁄4 The set of transitions Tj, j = 1... Note that it must be required that w is a firing sequence; allowing arbitrary sequences of transitions will generally produce a larger set. [17]
