Oct 23, 2025 – Maker Fest!


Calling all makers, hobbyists, etc.!

The Lone Star Chapter of the IEEE Robotics and Automation Society is holding a “maker fest,” and we’re looking for people to show off their home and hobby projects.  This meeting will be a good chance to show off the project you’ve been working on for your house, back yard, etc. The project does not need to be complete – in fact, this can be a good opportunity to get advice on how to get it finished! If you have a project that is too big to bring in, we can provide screens to show off images and videos of your work.

The meeting will be at Trinity University, in CSI-282 (Center for Sciences and Innovation, ground floor) and students are especially invited to attend.  

Sept 25, 2025 – ARTEMIS: A High-Performance Humanoid for Competitive Soccer

Mingzhang (Norman) Zhu, Ph.D. Student in the RoMeLa Lab at UCLA presented:

ARTEMIS, a 20-DoF humanoid robot built for high-performance autonomous soccer. Featuring custom quasi-direct drive actuators, lightweight legs, and flexure-based foot sensors, ARTEMIS achieves low inertia, strong kicking, and agile locomotion. A hierarchical control stack integrates predictive models with full-order tracking, enabling stable walking, precise ball handling, and responsive planning. With integrated vision, localization, and behavior-tree high-level control, ARTEMIS perceives the game state and executes soccer behaviors autonomously. At RoboCup 2024, ARTEMIS won the Adult Size League with 45 goals in six matches, establishing a benchmark platform for advancing dynamic humanoid robotics.

The recording will remain available for 90 days after the presentation.

June 26, 2025 – Actuator Design for In-Space Operations

Abstract: Full state feedback (FSF) controllers for series elastic actuators bridge the gap between impedance and admittance controllers. For robot manipulators-which must stably accomplish both stiff and soft behaviors-FSF controllers are ideal candidate joint controllers. Although previous work on FSF gain tuning has derived necessary and sufficient conditions on controller passivity with time-delay and derivative filtering, they fail to achieve their target impedance behavior due to the large nonlinear friction found in the high gear-reduction actuators of robot manipulators. In this talk, I will discuss the history, advantages, and disadvantages of adaptive friction models and friction observers. I will then present a novel, back-drivable friction compensator that combines an adaptive Karnopp friction model in parallel with dual disturbance observers for model training and disturbance attenuation. Low-speed time-domain demonstrations show an improvement in trajectory tracking for the combined compensator over separate modeled or unmodeled approaches.

Apr 24, 2025 – SubArc: An Inexpensive, High Resolution, Open Source, Absolute Magnetic Rotary Encoder

Presenter: Frank Lucci — Junior at BASIS San Antonio Shavano High School, Winner of LSS RAS Special Science Fair award for “Outstanding Robotics & Automation Project – Senior Division”
High resolution absolute rotary encoders are essential to precision applications like tracking telescopes, semiconductor manufacturing, low-tolerance machining, and robotic mechanisms. However, high-end encoders are extremely expensive ranging from hundreds to thousands of dollars for those with 20 to 22+ bit resolution, respectively. The cost and proprietary information barriers of these encoders prevent independent researchers, small institutions, and others with limited budgets from researching, developing, and using precision equipment.
To address this issue, a novel, low-cost, customizable, open source, high resolution, absolute magnetic rotary encoder was invented with a similar performance and environmental robustness to the high-cost counterparts. The final engineering goal was to create a base prototype, easily modifiable to further increase resolution, for less than $40, with a calibrated 20-bit resolution, sub 150 arcsecond accuracy, sub 3-in diameter, and ability to compensate for fluctuating temperatures and external magnetic fields.
After much iteration and tuning, the final design successfully had a 20-bit resolution with detectable +-10 microtesla changes per tick. The average accuracy was successfully under 150 arcseconds at 0.0384 degrees with a standard deviation of 0.0308 degrees in comparison to the calibration encoder. Temperature, external magnetic field, and encoder mounting compensations were all successfully integrated. The unit cost was $24.84, and the diameter was 2.17 inches. Finally, high-precision robotics is now accessible, and robotics and manufacturing companies can save millions and reduce prices with the successful encoder design made open source for any person or entity to replicate, modify, and use.

Talk: What is the Next Industrial Revolution?

Human beings have experienced two major industrial revolutions. The first one took place in the 19th century, which replaced muscle power from humans and animals with mechanical power. The second one started in the middle 20th century, which provided people and societies with Internet. It was built with the technologies from computing, communication, networking and information storage. Both offered unprecedented productivity increases. What will be the next one? This talk intends to answer this question by presenting some recent development of Internet of Things (IoT) and smart systems. IoT was selected by IEEE as a major initiative to develop and advance over the next few years. Several recent studies have predicted the huge growth of IoT and tremendous benefits to the world economy. It was expected that 26 billion IoT units would be installed by year 2020, generating $300 billion in revenue. The IoT will generate an additional $1.9 trillion in economic value. We plan to present a system engineering approach to Internet-of-Things-based smart systems and their applications to smart manufacturing, smart cities, smart gird, smart logistics, and smart healthcare services.

Nov 4, 2022 – Joint meeting of the UTSA Student Branch, the RAS Chapter and the SMC/AES/SYSC Chapter

Dr. Premachandra of Shibaura Institute of Technology

Topic: Voice-based victim searching in disaster-stricken areas using drone

Drone searches for victims in disaster-stricken areas have been mainly conducted by analyzing images from cameras mounted on drones. But in disaster-stricken areas, victims may not be able to recognize victims from images, due to situations such as being covered in sediment and debris. Therefore, as a method of searching for victims who are not captured by the camera, a method of determining the location of the victim by mounting a microphone device on a drone and detecting human voices from the collected sound is being studied. This talk will discuss the approaches of searching disaster victims by voice processing and related automatic flight control technologies for the searching activities.

Biography:

Chinthaka Premachandra (Senior Member, IEEE) was born in Sri Lanka. He received the B.Sc. and M.Sc. degrees from Mie University, Tsu, Japan, in 2006 and 2008, respectively, and the Ph.D. degree from Nagoya University, Nagoya, Japan, in 2011.

Sept 28, 2022 – Fluid Exoskeletons for Self-Assistive and Resistive Exercise

Dr. Emma Treadway spoke on “Fluid Exoskeletons for Self-Assistive and -Resistive Exercise” to the IEEE Robotics & Automation Society – Lone Star Chapter and interested students.

Program Description: Exoskeletons are promising for applications ranging from motor rehabilitation to active assist and zero-gravity exercise. In typical motorized exoskeletons, high torque requirements require the use of heavy motors. Fluid actuators on the other hand have relatively high power density (high power relative to their weight) and open the door to new rehabilitation and exercise paradigms inspired by the use of fluid transmissions. This talk explores the development and control of exoskeletons exploiting fluid transmissions to inspire two paradigms for exercise and rehabilitation: self-assist and self-resist. In self-assist, power is transmitted across the wearer’s body from a stronger joint to a weaker one via a fluid transmission in order to provide assistive forces during movement; this paradigm is attractive for applications such as stroke rehabilitation, in which patients often have stronger and weaker limbs. Self-resist on the other hand employs a fluid link to allow muscles to work against each other during exercise. Because this resistance exercise can be achieved without external grounding, it has potential application for zero-gravity exercise.

Bio: Dr. Emma Treadway is an Assistant Professor in the Department of Engineering Science at Trinity University. She received her M.S.E. and Ph.D. degrees in Mechanical Engineering from the University of Michigan, Ann Arbor in 2017 and 2019, respectively, and the B.S. degree in Engineering Science from Trinity University in 2011. Her research explores haptics and physical interactions between humans and
robots.

June 23, 2022 – Cybersecurity Concerns of Industrial Systems

Dr. Victor Murray

Our meeting featured a presentation on Industrial Cybersecurity from Victor Murray, manager of the Cyber-Physical Systems Security Section at Southwest Research Institute (SwRI). He is a Certified Information Systems Security Professional (CISSP) whose background includes performing risk assessments, penetration tests, and developing secure systems. His presentation will take a closer look at vulnerabilities and mitigation strategies for iROS and other computer controlled automation systems.

Program:

Robotics and industrial automation systems can be exposed to cybersecurity attacks but the threats are different than for personal or business systems.   This presentation considers vulnerabilities and mitigation strategies for iROS and other computer controlled automation systems.

News headlines occasionally tell of personal data leaks or financial breaches but actually multiple cyber-attacks are published on a daily basis. While the vast majority of cyber-attacks focus on traditional IT networks, there are many examples of attacks designed to exploit industrial systems.

This presentation will review some attacks that grabbed headlines including Colonial Pipeline, Stuxnet, and Triton Malware attacks. Unfortunately, bleeding edge industries, including robotics and industrial control, tend to be laser focused on functionality at the expense of cybersecurity. There are countless examples in other industries (blue tooth, Wi-Fi, CAN bus) where similar evolutions have occurred:

  1. No security, system just functions in the clear
  2. Technology takes off in popularity
  3. Technology gets hacked
  4. System gets re-designed to address security.

ROS-I for example commonly sends data over TCP/UDP connections in the clear. This can mean that if an attacker gets access to a ROS-I network then they have full control over your system. ROS 2 is moving towards addressing this with DDS-security, but this is not commonly used for ROS-I.

Jan 27, 2022 – Indy Autonomous Vehicle Challenge – Dr. Kris Kozak

Program Information:

The Indy Autonomous Challenge (IAC)  was ambitiously conceived of as a wheel-to-wheel race of fully autonomous race cars on the Indianapolis Motor Speedway (IMS) oval. Although a multi-car race didn’t materialize as envisioned, an exciting and boundary pushing competition was still held on schedule at IMS on October 23, 2021. The success of that IAC competition has since led to a follow-on competition at the Las Vegas Motor Speedway during the 2022 Consumer Electronics Show (CES) on January 7: the Autonomous Challenge at CES. For this presentation, Dr. Kris Kozak will give a behind the scenes look at the process that led up to the original competition, provide insight into the technologies used in the cars, and touch on some of the unique challenges that were faced by competitors.

Dec 9, 2021 – The application of drone imagery and structure-from-motion modeling to 3D volume analysis: a new era of scientific investigation – Dr. Ben Surpless

Joint Meeting of Trinity IEEE Student Branch and IEEE Robotics & Automation Chapter

Abstract: Unmanned aerial vehicles (UAVs) have become an increasingly integral part of industrial operations and scientific investigations.  As costs of operating and maintaining UAVs have come down over the past decade, scientists are now able to inexpensively, efficiently, and accurately collect remotely-sensed data from localities once thought inaccessible.  When combined with recent advances in hardware and software, scientists across a range of disciplines can now address research questions once thought, literally, out of reach.  In addition to reviewing recent changes in drone use and operation, Surpless will explore how drone data are collected and analyzed in the context of a real-world geologic investigation.

Speaker:  Ben Surpless is Professor of Geosciences at Trinity University, where he has performed research with students since 2005.   Ben earned his Ph.D. in geosciences from Stanford University and has been awarded several National Science Foundation awards to support his research with students.  He was awarded the 2013 Junior Faculty Teaching and Research Award and the 2020 Z.T. Scott Fellowship, for excellence in teaching and advising.
