The designed surveillance robot is a remotely operated mobile robot by a human operator through a personal computer, capable of moving on a smooth terrain as directed by the human operator and providing the operator with live video feedback of its surrounding using an onboard wireless camera. We have designed the robot in such a way that it is operated by sending navigation commands through a Graphical User Interface (GUI) built on a personal computer by using MATLAB�. These commands are transmitted wirelessly using XBee transmitter and receiver modules, one connected to the computer and other to Arduino controller board on the robot. Two DC motors are used for actuation. Position and velocity of motors is controlled by using PWM signals generated by programming Arduino in C language. For surveillance purpose a wireless camera is installed on the robot. It sends live video to the computer, which can be viewed in the GUI. The robot during its motion can avoid collision with nearby objects by using a range sensor. Additionally, a feature relevant to ‘Machine Vision’ has been added i.e. quality inspection to identify circular objects etc.
