This article focus on Autonomous Robot, which is intelligent machines capable of performing tasks in the world by themselves, without explicit human control. These self-reliant robots can move themselves throughout the operation without human assistance, and are able to avoid situations that are harmful to themselves or people and property. Autonomous robots are helpful in busy environments, like a hospital. Some modern factory robots are “autonomous” within the strict confines of their direct environment. It may not be that every degree of freedom exists in their surrounding environment, but the factory robot’s workplace is challenging and can often contain chaotic, unpredicted variables.
