Precision timing is the backbone of reliable positioning, navigation, and timing (PNT) systems, but it’s also where failures can first occur. When GNSS signals degrade or disappear, even tiny clock errors can lead to major navigation drift. This whitepaper, published by SiTime, explores how advanced timing solutions improve resilience, enabling systems to maintain accuracy through interference, harsh environments, and outages. From MEMS-based oscillators to multi-source data fusion, the future of PNT is about redundancy, trust, and other factors. As reliance on PNT grows across industries, building robust timing architectures is no longer optional; it’s essential for safety and infrastructure continuity.

Why give your robot hands when it can have tentacles instead? Meet Mr. O.C.K [Octopus Control Kinematics] the soft robotic octopus arm. Made by Formlabs interns Margaret & Vishesh during their weekend hackathon, they rapidly prototyped 15 different tentacles using Formlabs Form 4 ecosystem and Flexible 80A resin. The robot arm moves using fishing line and simple motors, which are capable of underactuated multi-directional movement or gripping objects with two tentacles. This remarkable robot arm extends and carefully grasps a glass of water. Video Credit: Formlabs

Casey Harrell, a man living with Amyotrophic Lateral Sclerosis, has become one of the most advanced users of a brain-computer interface (BCI), using an implanted device to communicate, browse the web, and continue working despite being largely paralyzed. After nearly three years of use, the system translates neural activity into text and speech, restoring much of his ability to interact with others. Researchers see Harrell’s extensive real-world use as a major milestone for BCI technology, demonstrating its potential to improve independence, communication, and quality of life for people with severe neurological conditions.

Before returning to Earth, REACCH was tested aboard the International Space Station. Defunct or off-course satellites can remain in orbit for years, increasing congestion and the risk of collisions. Many were not designed to be serviced, repaired, or removed once deployed, making them difficult to manage at the end of their operational life. During testing on the International Space Station, REACCH demonstrated the ability to capture a variety of unprepared objects without causing damage. The system combines gecko-inspired adhesive technology with mechanical articulation to securely grasp objects with different shapes and surfaces. Video Credit: Kall Morris Inc

This new microrobot is only 4.4mm long, but it can perform a whole host of surgical procedures, such as cutting tissue, releasing medical drugs, gripping and storing samples and generating heat for hyperthermic treatments. Developed by NTU scientists, the robot is controlled remotely by magnets and can move across soft and uneven surfaces like those found inside the human body. This robotic innovation could allow doctors to make minimally invasive surgeries even less invasive, reducing the risk to patients while improving the precision of these surgeries.

This Arduino-powered project combines 120 FPS custom image processing with smooth stepper motor control to balance and direct an orange ping pong ball. By tracking the ball in real time and calculating its 3D position, the system continuously adjusts the platform to control the ball's movement. In this video, the creator demonstrates new bouncing patterns. These capabilities were made possible through major upgrades to the Unity-based control system, including a redesigned ball-detection algorithm, improved data visualization, hit-position prediction using gradient descent, real-time tilt visualization, analytical tilt control, and support for two-step bouncing. Together, these enhancements enable more accurate tracking and increasingly sophisticated ball-control behaviors. Video Credit: YouTube/ Electron Dust

Allonic has developed a 3D tissue-braiding machine that mimics how connective tissue wraps around bone. By weaving high-strength fibers around a minimal skeleton, it creates tendons, soft tissue, and compliant structures in a single automated process, without screws, cables, or complex joints. The result is a rapid, low-cost path from digital design to physical part, potentially enabling disposable robotic end-effectors. It could help solve one of humanoid robotics’ toughest challenges: dexterous manipulation. Video Credit: Allonic

Cornell engineers have developed a robotic collective that behaves less like a machine and more like a material that flows, reshapes, and adapts to its environment without centralized control. The system, called the Cross-Link Collective, consists of dozens of small robots that have limited mobility individually, but together exhibit coordinated and sustained motion. The research demonstrates a robotic system that resembles soft matter, continuously deforming and reorganizing as it moves, driven by what researchers call mechanical intelligence.

This installation enables a live plant to control a machete. Plant machete has a control system that reads and utilizes the electrical noises found in a live philodendron. The system uses an open-source microcontroller connected to the plant to read varying resistance signals across the plant’s leaves. Using custom software, these signals are mapped in real-time to the movements of the joints of the industrial robot holding a machete. In this way, the movements of the machete are determined based on input from the plant. Essentially, the plant is the brain of the robot, controlling the machete, determining how it swings, jabs, slices, and interacts in space. Video Credit: David Bowen

ABENICS: Active Ball Joint Mechanism With Three-DoF Based on Spherical Gear Meshing. The gear-based joint drives three rotational degrees of freedom (RDoF) without slippage. The capabilities were inspired by the unique interactions between two different innovative gears [the cross spherical gear (CS-gear) and monopole gear (MP-gear)] and the superimposition of those interactions by the CS-gear’s quadrature spherical tooth structure.

The latest ARCOS TCA hot-fire campaign at the German Aerospace Center marked a major milestone in the development of ARCOS’ in-house methalox thrust chamber assembly. Across 10 successful ignitions and 790 seconds of cumulative hot-fire time, the campaign demonstrated stable and repeatable performance over a wide operating envelope, including 60–105% thrust and multiple mixture ratios. Testing validated a deeply throttleable core thrust module designed for replication across ARCOS’ aerospike architecture. Reliable ignition and shutdown behaviour, stable chamber pressure performance, and no critical structural damage were observed throughout the campaign. Video Credit: Pangea Propulsion
