Abstract

A head unit system for controlling motion of an object includes an environment sensor and a head unit device that include shear thickening fluid (STF) and a chamber configured to contain the STF. The chamber further includes front and back channels. The head unit device further includes a piston housed at least partially radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypasses to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid flow sensors and a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber to abate an external factor of concern associated with an external environment as sensed by the environment sensor.
