Modular rotating shear thickening fluid based object control mechanism

A head unit system for controlling motion of an object, the head unit system comprising:

• a first shear thickening fluid (STF) module, wherein the first STF module includes:
• a first shear thickening fluid (STF), wherein the first 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 first chamber, the first chamber configured to contain a portion of the first STF, wherein the first chamber includes a first front channel and a first back channel;
• a first set of gates, the first set of gates configured to separate the first front channel and the first back channel to control velocity of flow of the first STF between the first front channel and the first back channel, wherein the first set of gates is further configured to enable the first STF to provide the first range of shear rates as the first STF flows from the first back channel to the first front channel when the first set of gates is in an open position, wherein the first set of gates is further configured to enable the first STF to provide the second range of shear rates as the first STF flows from the first front channel to the first back channel when the first set of gates is in a closed position;
• a first piston, the first piston housed at least partially radially within the first chamber, the first piston configured to include a first slot set, wherein the first piston is further configured to facilitate flow of the first STF through the first slot set between the first front channel and the first back channel when the first piston travels longitudinally within the first chamber;
• and
• a first plunger, the first plunger housed at least partially radially within the first back channel of the first chamber, wherein the first plunger is configured to exert force on the first piston in response to the motion of the object;
• a second shear thickening fluid (STF) module, wherein the second STF module includes:
• a second shear thickening fluid (STF), wherein the second STF is configured to have the decreasing viscosity in response to a third range of shear rates and the increasing viscosity in response to a fourth range of shear rates, wherein the fourth range of shear rates are greater than the third range of shear rates;
• a second chamber, the second chamber configured to contain a portion of the second STF, wherein the second chamber includes a second front channel and a second back channel;
• a second set of gates, the second set of gates configured to separate the second front channel and the second back channel to control velocity of flow of the second STF between the second front channel and the second back channel;
• a second piston, the second piston housed at least partially radially within the second chamber, the second piston configured to include a second slot set, wherein the second piston is further configured to facilitate flow of the second STF through the second slot set between the second front channel and the second back channel when the second piston travels longitudinally within the second chamber;
• and
• a second plunger, the second plunger housed at least partially radially within the second back channel of the second chamber, wherein the second plunger is configured to exert force on the second 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 first plunger and an outward force to the second plunger in response to a rotational force of the object, wherein the threaded plunger is further configured to generate the inward force to the first plunger and the outward force to the second plunger 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 first plunger and an inward force to the second plunger in response to a counter-rotational force of the object, wherein the threaded plunger is further configured to generate the outward force to the first plunger and the inward force to the second plunger when the nut counter-rotates on the threads of the threaded plunger as a result of the counter-rotational force of the object.
