Abstract
This paper presents a simple design and construction process of a robot that acts like a sniffer dog, named robotic dog, at the detection of any metals which may be harmful for human lives like bombs or valuable things like keys. The robotic dog (RD) consists of a metal detector system and an autonomous car embedded with an electronic buzzer system so that it acts as a real sniffer dog. The robotic vehicle can be controlled from a safe distance using Bluetooth technology. Based on our experimental studies, it was found that the RD can move freely in any direction. At the detection of metal anywhere, the RD locks itself on that position, the buzzer system starts barking like a dog, and it does not move forward until the metal is removed. This RD may have a wide range of uses because of its simplicity and low cost in construction. Moreover, it has the design flexibility to modify its shape to meet the changes of needs.
