Patent number: 10302181Abstract: A reconfigurable motion generator and control system for multi-phase motion generation. Reconfigurable motion generators are a new class of mechanical devices that are designed for a specific part family and their associated motion generation tasks. The reconfigurable motion generator may utilize revolute joints for link length and pivot adjustment to achieve different configurations from the same set of links. Due to the nature of adjustment of the mechanism this methodology may be used for different types of motion generation tasks such as (a) common start position, (b) common end position, (c) common intermediate position, and (d) distinct motion generation tasks with no common positions. This technique can be applied towards the synthesis of reconfigurable motion generators for use in many planar or spherical applications involving multi-phase function, path, and motion generation tasks.Type: GrantFiled: May 1, 2015Date of Patent: May 28, 2019Assignee: South Dakota School of Mines and TechnologyInventors: Pierre Larochelle, Venkatesh Venkataramanujam
