Three VSCL Engineers Co-Inventors on new US Patent for Autonomous Aircraft Taxiing

Posted on by

VSCL alumni Tiffany Williamson and Felix Turcios and current VSCL Ph.D. student Hannah Lehman are co-inventors on newly awarded US Patent 11,037,455, “Autonomous judgmental oversteering determination system for aircraft taxiing”. The system uses reinforcement learning  to create a system for an autonomous taxi assistance program. The program is designed to help pilots taxi around airports, especially in situations where oversteer is required and may be difficult for the pilot to properly judge.

Tiffany Williamson and Felix Turcios currently work at Collins Aerospace in Cedar Rapids Iowa as an Engineering Leader and Sr. Systems Engineer respectively. Hannah Lehman is a former Collins Aerospace summer intern with Tiffany and Felix in the Advanced Concepts Group. The team is expecting one more patent for the autonomous taxiing user interface in conjunction with this project.

MD-Nazmus Sunbeam is a Ph.D. student in the aerospace engineering department. He will graduate in May 2021 from the University of Texas at Austin with a B.S. degree in aerospace engineering. During his undergraduate studies, Sunbeam worked on making a chess AI by training neural nets through evolutionary algorithms using NEAT. Additionally, he assembled and configured quadcopters, using the drone footage to train object detection neural nets. He has experience implementing convolutional neural nets on different image classification and speech recognition problems. His research interests are AI/ML/robotics. In the fall at VSCL, Sunbeam will research Enhancing the Cycle-of-Learning for Autonomous Systems to Facilitate Human-Agent Teaming, which is sponsored by the Army Research Laboratory.

 

 

 

 

Ravi Kumar Thakur is a Ph.D. student in the aerospace engineering department.  His interest is in the field of aerospace robotics and autonomy. He graduated with an MS(Research) degree in Electronics and Communication from the Indian Institute of Information Technology Sri City, Chittoor in 2019. For his thesis, he worked on developing machine learning-based models for estimating scene flow from stereo images. He earned his BS in Engineering Physics from National Institute of Technology Calicut in 2014. In the past, he was a machine learning engineer at Ford Motor Company,  where he worked on driver assistant technology with a focus on visual odometry and object tracking. Before that, he worked at the Indian Institute of science working on the development of an endoscopy simulator. At VSCL, Thakur will be working on the project Enhancing the Cycle-of-Learning for Autonomous Systems to Facilitate Human-Agent Teaming which is sponsored by Army Research Laboratory.

 

 

 

David van Wijk is a Ph.D. student in the aerospace engineering department, funded by the College of Engineering Graduate Merit Fellowship. He will graduate in May of 2021 from Cornell University with a B.S. in Mechanical Engineering from the Sibley school of Mechanical and Aerospace Engineering. During his undergraduate studies, van Wijk was an active member in the Laboratory for Intelligent Systems and Controls under Professor Ferrari, concentrating on classical control for quadrotors, object detection, and mapping. His research contributed to a paper on Visibility-based Directional Sensor Path Planning submitted to IEEE Transactions on Robotics. He also interned at Northrop Grumman Remotec, focusing on mechanical design of hazardous duty robotic vehicles. He is interested in robotics, autonomous systems, and machine learning.

 

 

 

 

VSCL Graduate Student Chris Leshikar Awarded PhD Graduate Excellence Fellowship

Posted on by

Chris Leshikar ’20, a graduate research assistant in the Vehicle Systems & Control Laboratory (VSCL), has been awarded the PhD Graduate Excellence Fellowship for Spring/Summer 2021. This competitive fellowship awards $20,000 over the span of 8 months , in addition to covering tuition and fees. All graduate research assistants within the department of aerospace engineering pursuing a PhD starting in Spring 2021 were considered for this Fellowship.

Leshikar has been an active member of VSCL since Spring 2017, focusing on system identification and nonlinear multiple-time-scale control theory. He graduated with a B.S. degree in Aerospace Engineering with Engineering Honors in December 2020. As a graduate research assistant in VSCL, Leshikar will be focusing his research on control of uncertain nonlinear multiple-time-scale systems and near real-time online system identification. Dr. John Valasek will serve as his research Advisor and Chair of dissertation committee.

VSCL graduate student Hannah Lehman inducted into the AIAA Intelligent Systems Technical Committee

Posted on by

VSCL Graduate Research Assistant and Ph.D. student Hannah Lehman has been inducted into the AIAA Intelligent Systems Technical Committee (ISTC).  The ISTC is a group within AIAA that addresses the application of Intelligent System (IS) technologies and methods to aerospace systems, the verification and validation of these systems, and the education of the AIAA membership in the use of IS technologies in aerospace and other technical disciplines. Lehman was inducted due to her technical experience in IS and involvement with AIAA. She was previously a member of the AIAA Software Technical Committee.

Lehman’s undergraduate research experience and doctoral research aligns with the ISTC’s activities.  She is the recipient of the AIAA Foundation Cary Spitzer Digital Avionics Scholarship for her research contributions in Reinforcement Learning for the intelligent control of Unmanned Air Systems, and a Co-Inventor with Collins Aerospace on two patents for IS applied to airplane ground operations at airports.  Lehman researched IS for the 2019 NSF Research Experience for Undergraduates (REU) program, and for a 2020 summer internship with Sandia National Laboratories.  Her doctoral dissertation is sponsored by Sandia National Laboratories on the project Tightly Integrated Navigation and Guidance for Multiple Autonomous Agents.
