Design and analysis of UGV with rocker bogie mechanism for landmine extraction

Landmines are one of the earliest & deadliest devices used in military to destroy enemy targets. Mines are deployed in various terrains and hence the extraction of mines could be a challenging task. Under such circumstances, an Unmanned Ground Vehicle (UGV) with a rocker bogie mechanism would be able to accomplish the given task. Hence, a UGV with rocker bogie mechanism has been designed for the purpose of landmine extraction. The designed UGV is driven by two motors. One motor mounted to the wheels is responsible for the linear movement and the other is responsible for the steering. The rocker bogie mechanism is a six wheel standard design which acts as the suspension system that works in tandem with the differential and helps in rolling and maneuvering of the UGV in all terrains. The robotic arms and end effectors are designed for the extraction of the land mine. The End effector has two tools viz. drill bit and robotic grip. The drill bit helps in drilling all around the mine and the grip picks up the mine from the pit. The UGV is designed based on various design calculations and modelled using Autodesk Fusion 360 Software. The 3D model is further analyzed using Ansys Workbench software by simulating the various loads acting on the critical joints. At the end of the study it was found that the designed model did not prove any kind of failure during the simulations.
