Luis Sentis is a Spanish-American roboticist, a Professor in the Department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin, the director of the Human Centered Robotics Lab, and a co-founder and scientific advisor of Apptronik. He completed his Master of Science and PhD in Electrical Engineering at Stanford University under the supervision of Oussama Khatib, where his doctoral thesis developed the whole-body control framework that has been broadly influential in humanoid-robotics research. As of May 2026, Sentis remains the academic anchor for Apptronik's research lineage and a continuing principal investigator at UT Austin with NASA, ONR, NSF, DARPA, and ARL research funding.

Origins
Sentis was born in Spain and completed his undergraduate education at the Polytechnic University of Catalonia (Universitat Politècnica de Catalunya, UPC) in Barcelona with a Bachelor of Science in Telecommunications and Electronics Engineering. After undergraduate, he worked in Silicon Valley as a Control Systems Engineer for clean-room automation, an industrial-controls environment that informed his later interest in dynamic control of physical systems.
He entered Stanford University for graduate study in Electrical Engineering as a La Caixa Foundation Fellow, completing both his MS and PhD in the Stanford AI Lab under Oussama Khatib, one of the founding figures in modern robotics and the originator of the operational-space formulation for robot control. The PhD thesis, "Synthesis and Control of Whole-Body Behaviors in Humanoid Systems," developed a hierarchical task-and-posture decomposition for humanoid control that allows a robot to execute multiple simultaneous motion, force, and constraint tasks with a prioritized resolution of goal conflicts. Sentis and Khatib published the foundational paper on the framework, "A Whole-Body Control Framework for Humanoids Operating in Human Environments," at the IEEE International Conference on Robotics and Automation in 2006. The thesis was defended in 2007. The whole-body control formulation became one of the more-cited contributions in humanoid-robotics control through the late-2000s and 2010s.
Career
After Stanford, Sentis joined the faculty at UT Austin in the Department of Mechanical Engineering (and subsequently in the Department of Aerospace Engineering and Engineering Mechanics) and established the Human Centered Robotics Lab. The lab's stated research direction has spanned control, task and motion planning, human factors, and experimentation with humanoid robots, mobile manipulation robots, exoskeletons, and autonomous systems. Sentis's research has been funded by ONR, NASA, NSF, ARL, AFC, DARPA, and private companies; the cumulative-funding profile is one of the larger humanoid-robotics academic programs in the United States.
The most-visible institutional collaboration in the early Human Centered Robotics Lab period was the partnership with NASA Johnson Space Center on the Valkyrie humanoid robot. Valkyrie was NASA's first bipedal humanoid robot, a 44-degree-of-freedom series-elastic-actuator-based platform developed for the DARPA Robotics Challenge in 2013. Sentis served as UT Austin's lead on the project, helping to design and test the Valkyrie platform and contributing to the actuator-control work jointly with his then-PhD student Nick Paine. The collaboration produced the 2015 Journal of Field Robotics paper "Valkyrie: NASA's First Bipedal Humanoid Robot" and the actuator-control paper that has become a reference in series-elastic torque-control literature. NASA awarded Sentis the NASA Elite Team Award for his contributions to the Johnson Space Center Software Robotics and Simulation Division.
The founding of Apptronik in 2016 emerged from the same lab. The introduction came through Bill Welch, a retired Air Force Brigadier General and Austin entrepreneur, who connected Welch's mentee Jeff Cardenas (a UT Austin MSTC student at the time) with Sentis and Paine. The founding decision in March 2016 was to spin a commercial humanoid-robotics company out of the lab that would commercialize the actuator and whole-body control intellectual property developed through the Valkyrie collaboration. Sentis's role shifted from research-lab director to a co-founder and scientific advisor at the company. The continuing professorship at UT Austin and the lab directorship gave Apptronik a long-running academic anchor and a research-pipeline relationship that has persisted through the commercial scale-up of the Apollo humanoid platform.
Sentis has continued as a principal investigator on humanoid-robotics research at UT Austin alongside his Apptronik role. The research lineage from the lab has included the DRACO and DRACO 3 bipedal robots (custom-built by Apptronik and used as research platforms by the lab), reactive and predictive humanoid control work, and contributions to whole-body dynamic control of human-like robots. The lab has trained a generation of robotics PhD students whose subsequent careers include positions at Apptronik, Boston Dynamics, NASA-JSC, IHMC, and several international research institutions. Sentis is a founding member of the UT Robotics Portfolio Program and the UT Ethics of AI Portfolio Program, and a member of UT Austin's Good Systems initiative.

Open questions
- Academic-industrial dual role. Sentis combines a full professorship at UT Austin with a co-founder and scientific-advisor role at Apptronik. Whether the dual position scales as Apptronik enters high-rate commercial production, and whether the boundary between lab research and company intellectual property remains clearly defined, is a watchable institutional question.
- The whole-body control lineage in the foundation-model era. Sentis's whole-body control framework was developed for an era in which the control architecture was hand-engineered. The shift toward learned policies, vision-language-action models, and end-to-end neural control challenges the classical-control framing. Whether the whole-body control lineage continues to inform Apollo's design as the AI stack moves to a more learning-heavy approach, or whether the engineered control layer recedes, is one of the more interesting open technical questions.
- PhD-pipeline relationship with Apptronik. The Human Centered Robotics Lab has historically been a substantial source of engineering hires for Apptronik. Whether the academic pipeline continues to provide a competitive talent advantage, or whether Apptronik's hiring needs shift toward AI and large-scale software engineers from non-UT-Austin sources, will shape the company's research-to-engineering throughput.
- Lab research direction post-humanoid-commercialization. With the humanoid market now commercializing, the question for academic humanoid-robotics labs is what the next-decade research direction looks like. Sentis's lab choices over the next several years (more on learning, more on application-specific robotics, more on safety and assurance, or other) will be informative for the broader research community.
