Autonomous learning of objects using visual information is important to robotics as it can be used for local and global localization problems, and for service tasks such as searching for objects in unknown places. In a robot team, the learning process can be distributed among robots to reduce training time and produce more accurate models. This paper introduces a new learning framework where individual representations of objects are learned on-line by a robot team while traversing an environment without prior knowledge on the number or nature of the objects to learn. Individual concepts are shared among robots to improve their own concepts, combining information from other robots that saw the same object, and to acquire a new representation of an object not seen by the robot. Since the robots do not know in advance how many objects they will encounter, they need to decide whether they are seeing a new object or a known object. Objects are characterized by local and global features and a Bayesian approach is used to combine them, and to recognize objects. We empirically evaluated our approach with a real world robot team with very promising results.

Several years have passed since the CanSat concept was first proposed as an educational tool to teach space technology. This concept brought with it different applications such as a mobile system. This article presents the design and construction of such a system. The mission consisted of sending data via telemetry to a ground station (laptop) and returning to the starting point. This mission was carried out utilizing a rover-type vehicle, using the “v” methodology. The electronic cards and the mechanical parts that would make up the rover-type vehicle were designed. The electronic cards were built for their manufacture, and the mechanical parts were printed on a 3D printer. A rover-type CanSat capable of sending data through telemetry to a ground station (laptop) located 1 km away was built. In conclusion, the data transmission was received and traced by the ground station. A solution is presented with the rotation of the casing incorporating some vials to the motors. In the case of DC motors, it is recommended to place encoders to maintain the same speed as both motors.
