This project involves building a phone-controlled robot using Node.js, RN-XV WiFly, Arduino, and Twilio. The robot uses the Twilio Node.JS Module and the Twilio Rest Message API to connect to a server and receive commands from a user's phone call. The robot is equipped with sensors such as sonar and servos that allow it to move around and interact with its environment. The project requires setting up an Arduino board, connecting it to the WiFly module, writing code for the robot's movement and sensor functions, and creating a Twilio server-side application to handle incoming calls and send commands back to the robot.
