A Low-Cost Land Wheeled Autonomous Mini-robot for In-door Surveillance

This paper presents the design and construction of a land wheeled autonomous mini-robot (LWAMR) for in-door surveillance. The LWAMR is able to be autonomous by using a position, speed and distance sensor. In addition, it is capable to send images and video in real time by using a spy cam, which is controlled by a servomechanism. Details of the design, control algorithm, communication, and human machine interface (HMI) are given. HMI was implemented in LabVIEW and it is used for monitoring remotely the LWAMR health and surveillance. Communication between the HMI and the LWAMR system was carried out by means of RF transceiver. Results show the effective implementation of this kind of LWAMR system. Advantages of the presented LWAMR are: low cost, versatility, modularity, robustness and remote (or not) operation by using a mobile device HMI.
