Manufacturing system including mobile cart with trunnion axis control

A manufacturing system configured for processing a vehicle chassis, the manufacturing system comprising:

• work cell including:
• a cutting robot;
• a measuring robot;
• and
• a docking station including a drive unit;
• a mobile cart configured to be moved into and out of the work cell, the mobile cart including:
• a first rotatable member spaced apart from a second rotatable member, both the first rotatable member and the second rotatable member are configured to support and rotate the vehicle chassis about a trunnion axis of the vehicle chassis;
• and
• a mechanical coupling in cooperation with the first rotatable member, the mechanical coupling configured to cooperate with the drive unit of the docking station such that rotation of the drive unit rotates the mechanical coupling and the first rotatable member;
• and
• a control module configured to control the measuring robot and the drive unit, and incorporate the trunnion axis as an axis of the measuring robot;
• wherein:
• after rotation of the vehicle chassis by the first rotatable member and the second rotatable member about the trunnion axis, the control module is configured to identify a rotated position of the vehicle chassis and input the rotated position to the measuring robot;
• and
• the control module is configured to identify the rotated position based on at least one of a degree of rotation of the drive unit and location of a datum point on the vehicle chassis identified by the measuring robot.

A manufacturing system configured for processing a vehicle chassis, the manufacturing system comprising:

• work cell including:
• a cutting robot;
• a measuring robot;
• a docking station including a drive unit;
• and
• a control module configured to simultaneously control the drive unit and the cutting robot;
• and
• a mobile cart configured to be moved into and out of the work cell and docked with the docking station, the mobile cart including:
• a first rotatable member spaced apart from a second rotatable member, both the first rotatable member and the second rotatable member are configured to support the vehicle chassis for rotation about a trunnion axis of the vehicle chassis;
• and
• a mechanical coupling in cooperation with the first rotatable member, the mechanical coupling configured to cooperate with the drive unit of the docking station such that rotation of the drive unit rotates the mechanical coupling and the first rotatable member;
• wherein the control module is configured to:
• incorporate the trunnion axis as an axis of the cutting robot;
• and
• simultaneously control the drive unit to rotate the vehicle chassis about the trunnion axis and control the cutting robot to cut the vehicle chassis.
