1. A fluidic tactile sensor comprising:
a core comprising an outer core portion, an inner core portion, and a plurality of first channels having first openings at a plurality of first surface portions of the outer core portion, wherein the outer core portion comprises a network of second channels;
an elastic skin disposed over the first surface portions, wherein portions of the elastic skin extend into and sealingly engage the network of second channels;
a plurality of cells formed between the first surface portions and the elastic skin and fluidly connected to the plurality of first channels, each of the cells containing a fluid, wherein a contact force applied to the elastic skin at a first location corresponding to one of the cells produces a measurable change in fluid pressure inside the one of the cells: and
a plurality of pressure transducers arranged to measure fluid pressure in the cells.
