Surgical instrument including MEMS devices

A robotic system for performing surgical tasks, the robotic system comprising:

• a robotic arm;
• an actuation assembly operatively associated with the robotic arm for controlling operation and movement of the robotic arm, the actuation assembly including a processor for storing operational commands;
• a loading unit releasably connected to the robotic arm and including:
• a head portion for housing an electro-mechanical assembly configured to receive signals from the processor of the actuation assembly;
• a pair of jaw members coupled to the head portion;
• and
• at least one micro-electromechanical system (MEMS) device positioned on at least one jaw member of the pair of jaw members, wherein the at least one MEMS device includes:
• an energy producing device;
• and
• a sensor configured to sense energy produced by the energy producing device, the at least one MEMS device being configured to determine a distance between the pair of jaw members by timing a duration between initial energy sensing by the sensor and activation of the energy producing device.
