Cloud based low cost educational robot

This paper presents a novel Internet and Telephony cloud based system for low cost educational robotics. A webserver provides a web based on-line application that allows students to write block based or textual programs for a robot. When the program is executed, this server calls a standard mobile phone using the public switched telephony network and uses the telephony audio channel to send actuator commands and read sensors through audio tones. The proposed architecture allows the construction of low cost educational robots that can be programmed and controlled from the web via any mobile phone that can receive calls and has standard earphone connectors.
