Mumbai: Grazing animals return home in the evening, cats also return home without forgetting their owner, and pigeons return to their nest after a long flight. Researchers at the Indian Institute of Technology (IIT) Bombay have solved the mystery of how they remember this path, how they find their way.
To solve the mystery behind the natural homing behavior of animals, IIT Bombay studied the physical actions of living things. In this, automatic robots (robots) of several centimeters in size were designed to imitate the activities of living organisms. It simulated the activity of animals in search of food and the skill of returning to the original place. Animals move freely in search of food. Such instructions were given to the robot. Due to the rotational propagation of the robot, it was moving around, changing its direction on its own. Separate programming was inserted into the robot to find its way by considering the guiding light. The robot returned to its original position as the light level changed. Dr. Nitin Kumar, Assistant Professor, Department of Physics, IIT Mumbai, said, then the animals must be finding their original route using changes in sunlight and some other environmental cues.
The research also found that regardless of the difficult conditions, the animals returned to their original location based on the sunlight and direction, emerging from the extreme conditions faced by the robot. Along with the real robot, the researchers also created a virtual robot simulating the movements of the animals. Both got the same result. They also checked the route of the pigeon fleet during the homecoming process. In that too the researchers drew a conclusion. Therefore, due to this study it has become possible to understand how animals find their way at dusk. In future studies, the researchers aim to detect changes in light intensity over time and space and also add more road obstacles to the robot.
