Claim 15:
16. The robotic platform of claim 1, wherein, for the at least one first rotational element, the suspension includes:
a bearing block;
a wheel shaft coupled at one end to the at least one first rotational element and extending through a bearing in the bearing block on another end;
two suspension shafts extending approximately perpendicularly to the wheel shaft, each suspension shaft coupled to the chassis and extending through at least a portion of the bearing block; and
two springs, each spring corresponding to and disposed around one of the suspension shafts;
wherein the springs maintain a force on the wheel shaft sufficient to maintain the chassis above the ground during operation and compress to ground out the chassis when the chassis is subjected to a pre-determined load greater than the load when supporting the soft target.
