FIELD: transport.SUBSTANCE: wheeled robot chassis includes rectangular frame, two driving wheels of larger diameter and with rigidly fixed axles, two passive wheels of minor diameter and freely rotating around vertical axis, and the fifth passive wheel of larger diameter and with rigidly fixed axle. Herewith, the driving wheels are located at corners in front of the frame, two passive wheels of minor diameter are located at corners behind the frame, and the fifth passive wheel is located in the middle between passive wheels of minor diameter. In this structure, distance from lowest point of the fifth wheel to floor is less than half of diameter of passive wheels of minor diameter.EFFECT: possibility to cross thresholds of door openings while keeping stability.3 dwg |
