This article presents the development process of a mobile robot prototype, with Bluetooth communication that can operate in two modes: the first one, as a line follower, moving along a path that has been defined by a black line drawn on a white surface. The second mode of operation is as an obstacle detector, in which it moves forward trying to avoid the obstacles that appear on the way. The final prototype that was obtained works correctly in both modes, and serves as a platform for the development of automatically guided vehicles.
