  • Magnetically coupled ball drive for actuation of spherical surfaces
    Patent number: 12051958
    Abstract: A magnetically coupled ball drive system for actuation of spherical surfaces and wheels is disclosed. An internal support structure interacts with exterior drive wheels magnetically to produce rotational motion. A related improvement involving reduction of slip due to insufficient traction is also presented to establish a design for a more robust and versatile device that can be used in robotics or for producing vehicle locomotion.
    Type: Grant
    Filed: July 15, 2020
    Date of Patent: July 30, 2024
    Assignee: The Trustees of the Stevens Institute of Technology
    Inventors: Biruk Assefa Gebre, Kishore Pochiraju

  • Adaptive mechanism control and scanner positioning for improved three-dimensional laser scanning
    Patent number: 9322646
    Abstract: A method of adaptively positioning a scanner [10] within a three-dimensional scene identifies an optimal next position for the scanner [40] based on analysis of a data point cloud that mimics the scanned portion of the scene. Occluded areas [38] are delineated from scan data and scans made at different locations in the scene are registered to a reference four-coordinate system. The fourth coordinate corresponds to the hue observed by the scanner at each data point.
