A test fixture for determining calibration accuracy of an aircraft angle of attack sensor vane includes an outer disc, configured to be transiently fixed to an aircraft exterior portion surrounding the sensor vane, and an inner disc that includes a spring-loaded plunger configured to physically engage the sensor vane during tests. The inner disc is rotatable relative to the outer disc to accommodate rotation of the sensor vane when engaged with the inner disc. The outer disc includes a ring gear fixed thereto; the inner disc includes a manually operated knob containing a spur gear that reacts with the ring gear to rotate the inner disc when the knob is rotated. The outer disc is a clamshell structure formed of an upper annular disc and a lower annular disc rigidly secured together, and the inner disc is rotatably retained between the upper and lower annular discs.

Systems and methods are provided for controlling the motion of a tracked robot assembly. An exemplary method comprises disposing a mobile robot assembly proximate to a fuselage of an aircraft that is being assembled, aligning a left ranging sensor of the assembly with a left target, and aligning a right ranging sensor of the assembly with a right target. The method also includes directing the assembly to traverse to a location within the aircraft fuselage at which a robot on the assembly will perform work upon the fuselage, determining a left distance between the left ranging sensor and the left target while the assembly is moving, determining a right distance between the right ranging sensor and the right target while the assembly is moving, detecting a difference between the determined distances, and adjusting a direction of motion of the assembly based on the difference.
