Abstract: The disclosed haptic feedback system may include an actuator, a supply valve coupled to the actuator, an exhaust valve, and a fluidic mass controller communicatively coupled to the supply valve and the exhaust valve. The fluidic mass controller may (1) place the exhaust valve in a state that prevents a fluid from escaping the actuator, (2) activate the supply valve to fill the actuator with an amount of the fluid, (3) determine that the actuator has filled with the amount of the fluid, and then in response to that determination, (4) deactivate the supply valve to trap the amount of the fluid in the actuator. Various other apparatuses, methods, and systems are also disclosed.
