Trejo, F.R., Ortiz, M., Garcia, A., G.Vidal, J.C., E. Quesada, E.S., (2013), Design and Construction of Mini-Robot for Gas LP Detection Using a Mobile Device. IEEE Latin America Trasactions 11 (6), 1295-1300
In this paper, we present the design and construction of a mini-robot for gas LP detection with concentrations from 200 to 10,000 ppm. An application on a mobile device (tablet) to manipulate the mini-robot system, when it is not able to avoid an obstacle by itself, was carried out successfully. Also, this application recipes a signal when the mini-robot has detected an LP gas concentration and then, the mobile device activates an alarm and it sends automatically a signal to put the mini-robot in fully stop mode. The LP gas concentration for its detection is established in the control system, and this can be modified according to user needs. The communication between the mobile device and the mini-robot system was carried out by means of wireless protocol Bluetooth. In addition, the mini-robot can detect obstacles using an ultrasonic sensor, and also remember its last turn. The results show the effective implementation of this kind of mini-robot system, it has advantages such as: low cost, small, simple, and it uses a mobile device.
