Embodiment Construction

[0036] In some aspects, the systems and methods described herein can be used to more easily and efficiently plan material handling sequences to be performed by a tool coupled to and moved by a robotic tool handling system by utilizing One or more additional degrees of freedom available to the treatment system, such as manipulating the rotation of the tool about its longitudinal axis, and evaluating various potential robotic tool paths in an exhaustive manner to determine the most desirable tool path. In some cases, an exhaustive analysis can be performed by comparing the potentially desired robotic system configuration that will be able to deliver the tool in its intended location with the actual physical parameters of the robotic tool handling system, and based on known The physical parameters of the robot analyze whether the robotic tool handling system can indeed deliver the tool to the intended location, or whether one or more obstacles will limit the ability of the robotic...

Abstract

In some aspects, computer-implemented methods for selecting a robotic tool path for a manufacturing processing system to execute a material processing sequence in three-dimensional space can include:providing to a computer-readable product including robotic system data of a robotic tool handling system and workpiece data relating to a processing path of a tool along the workpiece; generating a plurality of possible robotic tool paths to be performed to move the tool along the processing path; identifying one or more obstacles, or an absence of obstacles, associated with the robotic tool paths; comparing robotic tool paths based on a predetermined robotic parameter to be controlled as the tool moves from the start point to the end point; and based on the identified obstacles, determining feasible tool paths, between the start point and the end point that avoid the obstacles, that can be obtained by adjusting the predetermined robotic parameter.

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 62 / 530,666, filed July 10, 2017, entitled "Automatic Path Planning," the contents of which are hereby incorporated by reference in their entirety incorporated into this article. technical field [0003] The present application relates generally to material handling systems, and more particularly to computer-implemented methods and systems for generating toolpaths for material handling robots. Background technique [0004] It has become a common trend in the manufacturing industry to perform material handling sequences by using robotic tool handling systems. Such manufacturing techniques can provide economical solutions for medium to low accuracy machining applications. However, planning for robotic tool paths can be challenging due to the complexity of the robot kinematics of some robotic tool handling systems. Semi-graphical or semi-automatic approach...
