Proposal of a Mobile Robotic System (Mechatronic System)

There are many engineering challenges involved in exploring remote areas without human assistance and in particular there is a strong need in advanced Robotics. Robots must be able to function in unknown, unstructured environments. Robots are more précised and it can be used where human involvement is dangerous, such as detecting Land Mines. We have developed a Robot which is completely Autonomous and it can also be controlled manually through Mobile phone. Robot interacts with human with the help of mobile communication and it accepts commands through Short Messaging Service (SMS). Robot is also provided with Infra-red sensors for Object detection and path finding mechanism. We have formed an algorithm for its autonomous operation and Artificial Intelligence through Micro-controller.

This paper proposes a new idea that will enable a mobile robotic system (Mechatronic System), to perform multiple tasks in a domestic environment such as

Identifying victims during disasters like Earthquake and Land Slides and reporting their location to rescuers with help of

CCD Camera and Global Positioning System.

Guiding a blind in any environment with the help of a guiding handle mounted over the Robot.

Detecting unusual situations such as trespasses, Land mines, fire, and gas leakage using a multiple sensor system.

Controlling the Robot from anywhere in the world through mobile phones using DTMF technology.

Robot sends messages (SMS) during critical situation to the user through the mobile phone provided in the Robot, which is interfaced to a micro-controller through a Data cable.

Object Recognition and Navigation for Autonomous operation through Infra-Red sensors.

Finding out the exact location of the Robot through Global Positi...
