Optimization of a Passive Parallelogram Suspension System for a Planetary Rover Using Differential Evolution

Stability analysis of the food delivery robot with suspension damping structure

“…The active adaptive suspension adapts to complex terrains by adjusting its own attitude, which is suitable for large and medium-sized unmanned vehicles; In comparison, the passive suspension structure is more suitable for smaller food delivery robots. Typical passive adaptive suspension structures include rocker-bogie suspension [16] , [17] , [18] , parallelogram suspension [19] , independent suspension [20] , [21] , and articulated rocker suspension [22] , [23] , [24] . In order to adapt to complex outdoor working environment, the existing suspension mechanism is comprehensively analyzed.…”
