Design of a quadruped robot for human–elephant conflict mitigation

Human–elephant conflict is a major problem leading to crop damage, human death by elephants and elephants being killed by people. The surveillance and tracking of elephant herds are difficult due to their size and nature of movement.
In this article, we propose a four-wheeled quadruped robot to mitigate human–elephant conflict. The robot can detect movement of wild pachyderms in certain pockets along the forest borders through which the elephants enter into the human living areas from the forest. The robot is so designed that it can navigate with wheels on flat terrains and with legs on unfriendly rugged terrains with the help of mounted cameras.
The images of the wild elephant are captured and transmitted to the base stations and an SMS is sent to the forest officials indicating an elephant is found. We obtain a suitable kinematic model for both legs and wheels with control algorithm for the quadruped robot to move along a predetermined path.
The quadruped robot proposed is a solution to detect elephant movement without affecting the ecological conditions to overcome human–elephant conflict. The unpredictability of time and location of elephant arrival into the villages are considered the major issues that are resolved in this work. The results of our work contribute to elephant conservation issues and are suitable for the detection of elephants in forest border areas.
