Abstract

A robotic vehicle may include a first chassis platform including a first wheel assembly, a second chassis platform including a second wheel assembly where the first and second chassis platforms are spaced apart from each other, and a combination linkage operably coupling the first and second chassis platforms. The combination linkage may be operably coupled to the first chassis platform via a first link and is operably coupled to the second chassis platform via a second link. The combination linkage employs at least two different coupling features to operably couple the first and second chassis platforms. The at least two different coupling features include at least any two among a fixed attachment, an attachment that enables rotation about a turning axis, and an attachment that enables pivoting about a pivot axis that is substantially perpendicular to the turning axis.
