AI Trash Cans That Can Trash Talk and Chase Garbage A Chinese DIY studio, tired of its messy workspace, decided to take smart cleaning to a whole new level. They went ahead and built 20 AI-powered trash bins that can detect, chase, and catch flying garbage, all while giving you lip if you miss. The team gave the trash bins cameras, embedded AI models to recognize thrown objects, and motors for movement. When a piece of trash flies… |

World's First Jet-Powered Hoverbike Opens for Preorder on August 1 A futuristic personal flying vehicle we previously covered will soon be available for pre-ordering. The Volonaut Airbike, developed by Polish inventor Tomasz Patan, is a jet-powered hoverbike. It is designed for a single rider and is capable of going as fast as 200 km/h. However, this is limited to 102 km/h for compliance reasons. A standout feature of the Airbike is its jet… |

A Robot That Picks Locks Using Physics, Not Sight In an ambitious experiment, a creator built a robotic lockpicker that can identify internal lock pins without a camera. It relies on force sensing and Hooke’s Law. This improves on previous versions of the project that took a brute-force approach, which cost up to a week trying every possible pin combination. The new version uses RC servo motors for quicker movement and mounts… |

3D Print Failure Detection Using AI with PrintGuard 3D printing failures are a waste of time, material, and energy. PrintGuard by Oliver Bravery offers real-time 3D print failure detection using AI on edge devices that addresses this. It’s designed specifically for edge devices like personal computers or embedded systems, and uses a custom computer vision model to achieve live monitoring through camera feeds and detect failures as and when they… |

CARA: A Rope-Driven Quadruped Robot Without Gears or Pulleys Over the past year, Aaed Musa built a robot dog called CARA, short for "Capstans Are Really Awesome". The design does not involve gears or pulleys like traditional ones. CARA uses something called capstan drives that move joints using ropes wrapped around rotating drums. This system has numerous advantages, such as zero backlash, high torque transparency, low inertia, low noise, and low cost… |

Mind Link: A DIY Brain-Computer Interface Built from Scratch Creator, AstroSam, built a functional prototype of a brain-computer interface (BCI), called Mind Link. It reads brain signals from a simulated 32-electrode array and sends them to a computer to visualize right away and possibly process later. The build combines custom PCBs, firmware, and magnetic connectors. The project is open-source and documented from scratch. The system consists of… |

EchoEar by Espressif: An Open-Source AI Kit for Voice and Smart Home Control Espressif has launched a new kit called EchoEar, a smart AI development kit. The demo application acts as a voice assistant. It listens to what you say, understands it, and responds naturally. It shows that it can go beyond talking like a human; it can even sing. The built-in conversational AI allows it to mimic human-like flaws and fillers like “like” and “you know”. The… |

Raspberry Pi-Based DIY Robot 'Saras' Combines Speech, Vision, and Autonomy Creator Jack Of All Tech built a personal robot that can move, speak, listen, respond, and make decisions all on its own. It’s called Saras, and the name stands for Smart Autonomous Robotic AI System. It’s made up of a Raspberry Pi, some sensors, wiring, 3D printed body parts, a microphone, a speaker, and DC motors. It has a wake word system, so it does not react to random sounds, just like… |

Zoborg: Cyborg Darkling Beetles with Elytra and Pronotum Implants Researchers, with support from The University of Queensland and other institutions, developed Zoborg, a living darkling beetle that was turned into a cyborg using an electronic wireless backpack mounted on its body. The backpack is tiny (15.8 mm x 5.8 mm, weighing 160 mg) and includes an ATtiny85V microcontroller and an infrared receiver. Electrodes are implanted in the elytra (hard covers on… |

AI Robots Play Football Without Human Control in Beijing Tournament Humanoid robots powered by AI engaged in a football match for the first time in Beijing, China, on June 28, 2025. Reports say that the robots dressed in black and purple jerseys took on each other in a 3 vs 3 match that was played in two 10-minute halves. The event featured four teams from three Chinese universities: Tsinghua University (THU Robotics), Beijing Information Science and… |

USC's Battery-Free Implant Aims to Provide Non-Addictive Pain Relief Reports say chronic pain affects 51.6 million Americans, and the effects are considered “high-impact” for about 17 million of them, influencing their life or work. Traditional methods of pain relief, such as opioid medications, carry the risk of addiction among other side effects. Current spinal cord stimulators are alternatives, but are expensive and require invasive surgery with a need for… |
