Abstract
A robotic vehicle (10) comprising a first chassis platform (200) comprising a first wheel assembly (202) and a second chassis platform (210) comprising a second wheel assembly (212). The first and second chassis platforms (200, 210) is arranged to be spaced apart from each other. The robotic vehicle (10) further comprises a linkage (220) operably coupled to the first chassis platform (200) and the second chassis platform (210). The linkage (220) being coupled so as to be fixed relative to the first chassis platform (200) and so that the second chassis platform (210) is rotatable relative to the first chassis platform (200), wherein the second chassis platform (210) comprises a turning axis (400). Said robotic vehicle (10) further comprising an electric brake (262) disposed proximate to a turning shaft (422) of the linkage (220). The electric brake (262) being selectively applied by processing circuitry (110) to resist turning of the second chassis platform (210) about the turning axis (400) and being selectively released to allow the second chassis platform (210) to turn about the turning axis (400).
