A Review on Load Carrying Chassis Structure of Robotics Tank System

The chassis structure forms the backbone of any robotic ground vehicle, playing a crucial role in supporting onboard systems and ensuring mobility, stability, and durability under varying load conditions. This study presents the design and structural analysis of a load-carrying chassis for a robotic tank system intended for off-road and rough terrain operations. The chassis is designed with a focus on optimal weight distribution, structural integrity, and adaptability to mechanical and electronic subsystems, including tracked propulsion units, batteries, sensors, and control modules. A material selection process favoring lightweight and high-strength materials, such as aluminum alloys, is undertaken to enhance mobility while maintaining durability. Finite Element Analysis (FEA) is employed to evaluate the chassis under static and dynamic loading conditions, simulating real-world forces including impact loads, distributed payloads, and torsional stresses. The results demonstrate that the proposed design ensures minimal deformation and stress concentration within acceptable limits, thereby validating its suitability for robotic tank applications. The study contributes to the development of robust, modular, and efficient chassis systems for autonomous ground robots operating in complex and demanding environments.
