All wheel drive robotic vehicle with steering brake
First Claim
1. A robotic vehicle comprising:
- a first chassis platform comprising a first wheel assembly;
a second chassis platform comprising a second wheel assembly, the first and second chassis platforms being spaced apart from each other;
a linkage operably coupled to the first chassis platform and the second chassis platform, such that the linkage is fixed relative to the first chassis platform, and such that the second chassis platform is rotatable relative to the first chassis platform, wherein the second chassis platform comprises a turning axis; and
an electric brake disposed proximate to a turning shaft of the linkage, the electric brake being selectively applied by processing circuitry to resist turning of the second chassis platform about the turning axis and being selectively released to allow the second chassis platform to turn about the turning axis.

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.
