Robotic system for confined space operations

A robotic system, comprising:

• a main drive unit having a mounting structure, and an arm storage unit coupled to the mounting structure;
• a non-actuated extendable arm unit coupled to the arm storage unit and configured to be moved axially in a predefined direction in a lateral plane from the arm storage unit, the non-actuated extendable arm unit having an elongated structure flexible and thin in the lateral plane relative to the vertical plane and rigid and wide in a vertical plane relative to the lateral plane;
• an axial drive unit coupled to the arm storage unit and configured to axially extend and retract the non-actuated extendable arm unit from the arm storage unit;
• an arm guidance member coupled to the arm storage unit to guide the non-actuated extendable arm unit in a predefined direction in the lateral plane during extension and retraction;
• and
• a head articulation unit coupled to a free end of the non-actuated extendable arm unit and configured to actuate and move the non-actuated extendable arm unit in varying directions in confined spaces and environments.
