Overview of suspension systems for mobile wheeled robots

A common type of transport system used in robotics is a wheeled platform with at least one drive axle and some form of suspension for each wheel. Autonomous navigation at high speed over rough terrain is a challenging and relevant task for wheeled robots. To achieve mobility on terrain, a wheeled robot must adapt and respond quickly. The suspension systems of mobile wheeled robots play a key role in ensuring their stability, maneuverability, and overall efficiency. This article presents a comprehensive overview of the different types of suspensions used in modern mobile wheeled robots. The main designs of passive and active, rigid and elastic suspensions are considered, as well as their features, advantages and disadvantages. As a result of the analysis, it was found that the optimal choice of suspension system depends on the specific operating conditions of the robot and the tasks set. For example, for robots operating in difficult terrain, suspensions with high damping are more suitable, while for robots performing precise maneuvers on a flat surface, suspension stiffness is more important. The article may be useful for engineers, researchers, and developers of robotic systems who seek to improve the designs of mobile wheeled robots and increase their efficiency and reliability. The conclusions and recommendations presented in the article can contribute to the development of new approaches to suspension design and optimization of existing solutions in the field of mobile robotics.
