Smart Contactless Water-Level Monitoring System Using SemLab-CLS-24BP The SemLab Contactless Liquid Level Sense Module is an open-source, liquid level sensor designed for non-invasive fluid detection. By utilising capacitive sensing, the sensor detects the presence of liquid inside a container or pipeline without making direct contact with the fluid. This non-contact design prevents sensor corrosion, contamination, and degradation… |

How to Learn ROS 2: A Practical Roadmap for Robotics Engineers ROS 2 has become one of the most important technologies for engineers interested in robotics. But beginners often struggle with the same questions: Should I learn ROS 1 first? Do I need a physical robot? Which programming language should I know? And is ROS actually used in production?We discussed these questions with Shubham Nandi, co-founder and Chief Research… |

Paintable Skin Electrode That Tracks Your Body Researchers from the Pennsylvania State University have developed a paintable on-skin dry electrode that sticks comfortably to the skin and reads biological signals with impressive stability. Because the sensor starts as a liquid paint, it flows into the microscopic lines, wrinkles, and pores of your skin before it dries. This creates a perfect, seamless bond that… |

FIFA World Cup 2026’s Trionda Ball Has a 500Hz Sensor Inside With the 2026 FIFA World Cup now under way across Canada, Mexico and the USA, adidas' official match ball, Trionda, is in use at all 104 matches of the tournament. Beyond the colour scheme tied to the three host nations, the ball's more interesting story for engineers is the sensor package built into it. Trionda uses the latest version of adidas' Connected Ball Technology, built around… |

Repurposing a Wear OS Smartwatch as a Smart Gear Shift Display A DIY maker has repurposed an old smartwatch into a custom gear knob with an integrated display. Instead of letting the aging smartwatch collect dust, the project reuses its display, sensors, and processing hardware inside a 3D-printed gear shifter housing. The result is a unique modification that displays the vehicle's current gear position directly on the gear lever itself. What I… |

A Homemade Approach to Long-Range Night Vision Most infrared night-vision systems are limited to relatively short distances mainly because standard IR LEDs spread light too widely to be effective over long ranges. Curious about the practical limits of infrared imaging, the independent engineering channel Project 326 developed a custom-built system aimed at long-range nighttime observation. The system combined a modified low cost… |

Autonomous High-Speed Swerving Vehicle using the VL53L5CX Sensor The primary objective is to develop a high-speed autonomous vehicle that utilizes a VL53L5CX multizone Lidar sensor to execute fluid, real-time swerving maneuvers instead of traditional "stop-and-turn" movements. By leveraging 8x8 spatial depth mapping, the system maintains continuous forward momentum while proactively navigating around obstacles via a timed S-curve… |

New Robotics Training Method Helps Simulated Skills Work in Reality Researchers at Aston University have developed a new AI-based robot training approach aimed at reducing the long-standing “sim-to-real” gap in robotics. The work focuses on improving how robots transfer skills learned in simulation into unpredictable real-world environments, where differences in material properties, sensor noise, and physical interaction often cause systems to fail despite… |
