Urgency of the research. Automatic battery charging of AGV platforms allows you to maximize their potential. Safe and quickly positioning AGVs in a charging station equipped with appropriate contacts, reduces the charging time as well as the purchase price of the device.

Target setting. The aim of the solution is to design an automatic docking and charging station from a used hand-held charging station. In the design, it was necessary to ensure the appropriate position of the AGV platform against the docking station.

Actual scientific researches and issues analysis. The issue of fast and reliable charging of mobile service robots is highly up-to-date. The reason for this is the growing deployment of AGV platforms in various industrial or service sectors.

Uninvestigated parts of general matters defining. This article focuses on a specific solution for the provision of transport services. Transport services come from the need to transport medical supplies and medications in a multi-storey hospital building. The movement of the robot between the floors is solved by the use of lifts used by the personal of hospital.

The research objective. The aim of the research was to design a docking and charging station utilized an already purchased power-up charger. The design was aimed at creating an appropriate power transmission system between the charger and the AGV platform batteries. The price ceiling for the whole facility was worth € 2,000.

The statement of basic materials. The use of docking and charging stations for mobile service robots is dependent on a number of parameters. In particular, the parameters depend on the area of use, the size of the battery to be charged, and the amount of robots being recharged at the station. Last but not least, charging time and purchase price are also important.

Conclusions. The task of the solution was to design a docking station design for the AGV platform. At the beginning, three variants were created, from which the most appropriate solution was chosen using the scoring method. However, before designing the docking station design, it was necessary to modify the existing AGV platform construction so that it could be connected to the docking station charging mechanism. The design of the docking station itself consisted of the design of the charging and charging mechanism. These mechanisms provide charge and guidance of the AGV platform to the docking station. Mechanisms are not dependent on each other, since the charging mechanism is activated later than the drive mechanism. Subsequently, a design of the docking station, which can be anchored to the floor or to the wall, was created. At the docking station there is a charger from Hoppecke, which provides the AGV platform charging. The design dimensions of the docking station have been greatly influenced by the size of the above-mentioned charger. It has been found that new and better technologies will not be needed at the docking stations in the future, as AGV platforms can be guided without their help. The development of new and better quality systems will bring new guidance options to AGV platforms and docking stations.
