Hydraulic-based spherical robot (Free Patents Online)
A system includes a plurality of fluid chambers uniformly distributed about
and in fluidic connection with a fluid reservoir, each fluid chamber having a
valve and pressure sensor adjacent thereto, the valve configured to allow
fluid flow between the fluid reservoir and the fluid chamber and the pressure
sensor configured to determine the amount of fluid within the respective fluid
chamber; means, adjacent to the fluid reservoir, for pumping fluid between the
fluid reservoir and each of the fluid chambers; and a controller configured to
control the means for pumping fluid and the valves using data from the
pressure sensors. The means for pumping fluid, the valves, the pressure
sensors, and the controller are contained within an inner housing and the
plurality of fluid chambers are contained within an outer housing, which may
be spherical in shape, and are external to the inner housing.
