In this paper, we focus on a Web-controlled mobile robot for home monitoring, in the context of Ambient Assisted Living. The key point is low-cost as dependent person have often tiny budget. The robot is built from standard components to reduce the cost of the hardware. A large part of the system is deported to the Internet to minimize the required software on the robot. Two low-cost positioning systems are also provided to make the robot more usable. The first one uses Received Signal Strength Indicators (RSSI), and the second one uses Infrared (IR) LEDs and an IR webcam. The result is a small robot that canbe used inside or outside the house
