AI summary

Systems and methods are disclosed herein for a robotic manipulator arm deployment and control system. The arm is operable to deploy tools, and one or more sensors including a non-contact sensor and a dynamic measurement unit. The non-contact sensor may be used for measuring range and bearing to objects in the operating space in polar coordinates to generate an electronic three-dimensional map of the operating space. The purpose of a three-dimensional map of the operating space is to define the boundaries of the operating space and any infrastructure or objects in the space that may restrict the RMA's range of motion in the space.
