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.
