1. A head unit system for controlling motion of a set of objects, comprising:
a set of secondary object sensors, wherein a secondary object is associated with the set of objects; and
a plurality of head unit devices, wherein each head unit device includes:
a shear thickening fluid (STF), wherein the STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates, wherein the second range of shear rates are greater than the first range of shear rates;
a chamber, the chamber configured to contain a portion of the STF, wherein the chamber includes a front channel and a back channel;
a piston housed at least partially radially within the chamber and separating the back channel and the front channel, the piston configured to exert pressure against the shear thickening fluid in response to movement of the piston from a force applied to the piston from a particular object of the set of objects, wherein the movement of the piston includes one of traveling through the chamber in an inward direction or traveling through the chamber in an outward direction, wherein the piston travels toward the back channel and away from the front channel when traveling in the inward direction, wherein the piston travels toward the front channel and away from the back channel when traveling in the outward direction, wherein the piston includes at least one of:
a first piston bypass between opposite sides of the piston that controls flow of the STF between the opposite sides of the piston between the back channel and the front channel to cause the STF to react with a first shear threshold effect, and
a second piston bypass between the opposite sides of the piston that controls flow of the STF between the opposite sides of the piston between the front channel and the back channel to cause the STF to react with a second shear threshold effect;
a set of fluid flow sensors positioned proximal to the chamber, wherein the set of fluid flow sensors provide a fluid response from the STF; and
a set of fluid manipulation emitters positioned proximal to the chamber, wherein the set of fluid manipulation emitters provide a fluid activation to at least one of the STF, the first piston bypass, and the second piston bypass to control the motion of the particular object of the set of objects with regards to the secondary object.
