1. A joint assembly comprising:
a housing having an inner wall surrounding an interior cavity of the housing,
a slider held captive in the interior cavity of the housing so as to define an annular volume extending radially between the slider and the inner wall of housing, the slider constrained to planar movement and a rotational degree of freedom in the housing, and
an annular resilient member in the annular volume, the annular resilient member exerting a biasing force between the slider and the housing toward a neutral configuration;
wherein the housing is adapted to be connected to one of a ground/base/motion platform and a linear actuator, and the slider is adapted to be connected to the other of the ground/base/motion platform and the linear actuator, the annular resilient member being a toroid in an uncompressed state.
