DETAILED DESCRIPTION
[0043] In accordance with various embodiments, the invention provides a method of mounting a large diameter cabling or hose on a multi-link mechanical system that (1) minimizes changes to the bending of a hose during motion, and (2) minimizes the maximum bending of such a hose in potential robot configurations.
[0044] Instead of bending in the plane of the motion of the rotating links (articulated arm sections), the hose is mounted in a way that it bends out of the plane of the articulated arm sections' motion. As shown in
[0045] As the attachment points are positioned closed to each other, the hose tangents at the attachment points become nearer to perpendicular to the plane of motion. As the attachment points are positioned more distant from each other, the hose tangent points become nearer to the plane of the link motion. In accordance with further aspects of the invention, as the sections rotate about a joint's axis of rotation, the hose slides through and/or rotates about attached mounts that swivel about mount axes of rotation.
[0046]
[0047] Though there remains a change in the bending during a motion, the degree of change in bending is lower than in a common hose routing scheme, as shown before. The strainor change in bendingover the course of the motions is lower than with the in-plane scheme.
[0048]
[0049]
[0050]
[0051] In accordance with various aspects of the invention, the vacuum at the end effector may have a flow rate of at least 100 cubic feet per minute, and a vacuum pressure of no more than 50,000 Pascals below atmospheric. The hose may have an inner diameter of at least 1 inch (or at least 3 inches), and may include a helical ribbing as discussed above.
[0052] To better show the system from multiple angles,
[0053] The hose routing of embodiments of the invention may be applied to a plurality of arm sections of an articulated arm system.
[0054]
[0055]
[0056] With reference to
[0057] The hose attachments may be fixed, may provide swiveling, and/or may provide for translation of the hose through the attachments in various aspects of the invention. The swivel attachments may also have more than one degree of freedom (DOF). While, the swivel may only allow rotation of the hose about an axis that is in the plane of the motion, a swivel joint may accommodate other additional DOFs including: the hose may twist through the mount to reduce torsion on the hose, the hose may slip through the mount to lengthen or shorten the hose segment between attachment points, and the attachment may permit small deflections of the rotation axis also to reduce total bending energy.
[0058]
[0059] The hose attachments 142 of the system 140 are fixed position, yet may optionally permit translation of the hose through the attachments as shown by the double ended arrows. The hose attachments 144 of the system 140 are swivel attachments that may rotate with the hose, and further may permit translation of the hose through the attachments as also shown by the double ended arrows. Note that the hose 86 in
[0060] The system may also provide hose routing in accordance with aspects of the invention including hose attachments on non-adjacent arm sections.
[0061]
[0062] Hose routing approaches of various embodiments of the invention allow for a chain of such kinds of attachments and hose segments to be provided that would exploit out-of-plane motions for a multi-link articulated arm programmable motion robotic system, with the objective of minimizing the maximum bending energy, and reducing the amount of cyclic loading to which the hose would be subjected.
[0063] Those skilled in the art will appreciate that modifications and variations may be made the above disclosed embodiments without departing from the spirit and scope of the present invention.
