Poppet valve system and method

A fluidic robot comprising:

• a plurality of inflatable fluidic actuators that define a plurality of pressure cavities, the inflatable fluidic actuators configured to be associated with and move one or more joints by inflation of the plurality of inflatable fluidic actuators;
• and
• a plurality of poppet valve systems disposed within respective pressure cavities of the inflatable actuators and configured to inflate the pressure cavity, the poppet valve systems comprising:
• a valve body having a first and second end and defining a valve cavity;
• and
• a poppet assembly extending from the first end to the second end and through the valve cavity, the poppet assembly comprising:
• a poppet head disposed at the first end of the poppet assembly and configured to move along a first axis and generate a seal by contacting a portion of the valve body and configured to define an opening between the valve cavity and a pressure cavity of an inflatable fluidic actuator;
• a movable diaphragm coupled at the second end of the valve body configured to move along the first axis;
• and
• a shaft extending from the first end to the second end and coupled to the poppet head and diaphragm, the shaft configured to move along the first axis.
