Prof. Simon Gröblacher from Delft University of Technology presented a seminar on using mechanical systems in quantum information processing, focusing on their potential as quantum memories and transducers. The seminar highlighted experiments demonstrating non-classical behavior of mechanical motion by coupling a micro-fabricated acoustic resonator to single optical photons. Quantum control over acoustic motion was established, including the generation and readout of single phononic excitations, along with light-matter entanglement. Why it matters: This research advances the use of micro-fabricated acoustic resonators for quantum information processing and fundamental tests of quantum physics.
This paper introduces a longitudinal control system for autonomous racing vehicles with combustion engines, translating trajectory-tracking commands into low-level vehicle controls like throttle, brake pressure, and gear selection. The modular design facilitates integration with various trajectory-tracking algorithms and vehicles. Experimental validation on the EAV24 racecar during the Abu Dhabi Autonomous Racing League at Yas Marina Circuit demonstrated the system's effectiveness, achieving longitudinal accelerations up to 25 m/s². Why it matters: This research contributes to the advancement of autonomous racing technology in the region, showcasing practical applications in high-performance scenarios and fostering innovation in vehicle control systems.
This paper presents the synthesis of a 1-DoF six-bar gripper mechanism for aerial grasping, designed for a task in the Mohamed Bin Zayed International Robotics Challenge (MBZIRC) 2020. The synthesis process involves selecting the mechanism class, determining the number of links and joints using algebraic methods, and optimizing link dimensions via geometric programming. The gripper was modeled in CAD software, additively manufactured, and mounted on a UAV with a DC motor for gripping spherical objects. Why it matters: The research contributes to advancements in robotics and aerial manipulation, with potential applications in various industries, particularly for tasks requiring remote object retrieval and manipulation.
A KAUST team led by Hossein Fariborzi won second place in the MEMS Design Contest for their "MEMS Resonator for Oscillator, Tunable Filter and Re-Programmable Logic Applications." The device is runtime-reprogrammable, allowing the function of each device in the circuit to be changed during operation. The KAUST team demonstrated that two MEMS resonators could replace over 20 transistors in applications like digital adders, reducing digital circuit complexity. Why it matters: This innovation could significantly reduce power consumption, chip area, and manufacturing costs in microprocessors, advancing the development of energy-efficient microcomputers in the region.

KAUST researchers have developed a passive cooling device that uses gravity and radiative cooling to extract water from the atmosphere without electricity. The device reflects thermal energy back to the sky while collecting water using gravity and a lubricant coating to eliminate water droplet pinning. Tested in Thuwal, Saudi Arabia, the system nearly doubled the water collection rate compared to other atmospheric water harvesting technologies. Why it matters: This innovation could improve the efficiency and adoption of solar cells in arid regions by providing a sustainable, electricity-free cooling and water harvesting solution.
Professor Mohammad Younis, a new Associate Professor of Mechanical Engineering at KAUST, focuses his research on micro and nanotechnology, specifically the interface between nonlinear dynamics and micro/nano electromechanical systems (MEMS and NEMS). He is developing a generic platform for sensing and actuation with potential uses in detecting poisonous gases, biohazards, and earthquake signals. He is also working on actuator systems that can assist elderly people after a fall by automatically calling for help. Why it matters: This research has significant implications for safety, environmental monitoring, and elderly care in the Middle East and beyond.
Munther Dahleh, director at the MIT Institute for Data, Systems, and Society (IDSS), discussed his group's research on network systems at the KAUST 2018 Winter Enrichment Program. The research focuses on the fragility of large networked systems, like highway systems, in response to disruptions that may lead to catastrophic failures. Dahleh's team studies transportation networks, electrical grids, and financial markets to understand system interconnection in causing systemic risk. Why it matters: Understanding networked systems is crucial for building resilient infrastructure and mitigating risks in critical sectors across the GCC region.
