Incorporation of mobile phones in small robotics applications like educational tool

The Learning based on Projects and/or Problem PBL-Problem/Project Based Learning, Case Method MdC or Challenge Problem CP allow that the students should acquire a more significant learning assuming, in turn, the responsibility of his own learning. At the same time the students develop another series of transverse competences related as: the teamwork, leadership capacity, critical thought, the search of information... Thus the utilization of a motivating didactic strategy that is capable of creating the intention of learning on the students is considered a key and revitalizing factor in the classroom. In this document it shows itself a simple application based on the incorporation of an old mobile phone Nokia 3310, Ericsson 750i or Siemens A55 to a small autonomous mobile robot in order transmit the instructions related to his orientation, navigation and displacement. The described application constitutes a factor of motivation extra on the students due principally to the curiosity and relevancy of the raised project.
