1. A head unit system for controlling motion of an object, the head unit system comprising:
a shear thickening fluid (STF) module, wherein the STF module 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 set of gates, the set of gates configured to separate the front channel and the back channel to control velocity of flow of the STF between the front channel and the back channel, wherein the set of gates is further configured to enable the STF to provide the first range of shear rates as the STF flows from the back channel to the front channel when the set of gates is in an open position, wherein the set of gates is further configured to enable the STF to provide the second range of shear rates as the STF flows from the front channel to the back channel when the set of gates is in a closed position;
a piston, the piston housed at least partially radially within the chamber, the piston configured to include a slot set, wherein the piston is further configured to facilitate flow of the STF through the slot set between the front channel and the back channel when the piston travels longitudinally within the chamber; and
a plunger, the plunger housed at least partially radially within the back channel of the chamber, wherein the plunger is configured to exert force on the piston in response to the motion of the object; and
a hinge module, wherein the hinge module includes:
a threaded plunger, the threaded plunger configured to facilitate an inward force to the plunger in response to a rotational force of the object, wherein the threaded plunger is further configured to generate the inward force when a nut rotates on threads of the threaded plunger as a result of the rotational force of the object, wherein the threaded plunger is further configured to facilitate an outward force to the plunger in response to a counter-rotational force of the object, wherein the threaded plunger is further configured to generate the outward force when the nut counter-rotates on the threads of the threaded plunger as a result of the counter-rotational force of the object.
