Abstract. The publication presents a three wheeled robot that has been designed to map rooms, halls and other indoor areas. The device uses an ultrasonic sensor for measuring distance, which is later used for both navigation and obstacle detection. Data were used later to compose a matrix -the schematic map of the room. This map could be uploaded to the cloud for later use by other 3rd party devices so they do not have to redo the mapping process again.

Abstract. Robotic arms are widely used in the industry, research and even in some consumer products. They are used to automate movements or to substitute humans for various reasons. These can be hazardous environment, for example radiation, extreme heat, lack of oxygen; or other factors, like long travel time as in case with the robotic arm of a Mars rover. In both cases, it is crucial to allow controlling the arm from the distance. The solution described in this research uses a cloud service to connect the client software and the device itself. The client application then can be deployed to computers, tablets, even mobile phones with internet access.
