Human Following Robot Using Arduino and Ultrasonic SensorWorking of Human Following Robot Using Arduino
In recent years, robotics has witnessed significant advancements, enabling the creation of intelligent machines that can interact with the environment. One exciting application of robotics is the development of human-following robots. These robots can track and follow a person autonomously, making them useful in various… |

Stuff Made Here Built an Arduino-Run Car Wash for His Muddy Dog, and the Dog Said No Anyone who has washed a muddy dog knows the real problem is not the mud on the dog. It is the shake that puts the mud on you. Shane Wighton of Stuff Made Here tackled it the way he tackles everything: he built a machine. His new video shows a car-wash-style rig for dogs, with an arch of moving nozzles that scans along a platform and sprayers underneath for the parts a hose never reaches. It… |

This 70 g Robot Butterfly Actually Flies, Flapping Two Servos From an ESP32-C3 Propellers make flying easy. Flapping wings do not. Maker Max Imagination still built ESP-FLUTTER, a 70 g remote-controlled butterfly that lifts off on its own wings, glows at night with LEDs along the wing edges, and can be flown from a phone browser. The firmware is open on GitHub, and the project was picked up by Hackster on 2 November. Two servos… |

This 3D-Printed Robot Duck Learned to Walk With a Neural Network, and Now It Kicks a Ball Most small walking robots replay hand-tuned servo sequences. XGO-Duck, an open-source biped from Luwu Dynamics, the team behind the XGO robot dogs, walks on a neural network policy instead. The network runs on the Linux side of an Arduino UNO Q, while the board's STM32 microcontroller handles the 15 serial bus servos and the orientation feedback. This weekend the team posted a clip of the duck… |

This Desk Buoy Copies the Live Motion of a Real Buoy at Sea, Hanging From 8 Stepper Lines A Belgian maritime pilot, whose job is guiding ships in and out of port, has built a desk piece that brings the sea indoors. His 30 cm 3D-printed west cardinal buoy hangs on eight lines, each wound by its own small stepper motor, and it rolls and heaves with live wave data from a real buoy out at sea. Pick a station off Bermuda and it moves to 1.9 m waves every 8 seconds; for some buoys it… |

A $300 Robot That Plays Fetch: It Finds the Ball, Picks It Up and Brings It Back on Its Own Most hobby robots that "follow a ball" just chase a colour blob. Sector 07 built one that plays a full game of fetch. His 3D-printed robot, called Fetch, uses an Arduino UNO Q and a custom vision model trained in Edge Impulse to find an orange ball, drive to it, grab it with two arms, then look for the owner's hand and bring the ball back, with no remote control. It is his first autonomous… |

A Robot Moth Pumped Artificial Blood Through Its Wings and Grew a Sensor It Never Had Every robot leaves the lab with its sensors already bolted on, picked from a best guess about where it will end up. Researchers at the University of Tartu in Estonia and the Italian Institute of Technology have built a moth-shaped robot that can add one later. They pumped an "artificial blood" through veins in its 3D-printed wings, shone UV light on a patch for about a minute, and that patch… |

This Robot Plays Othello Without Flipping a Single Disc, Thanks to 64 Color-Changing LEDs In Grade 11, maker Jeneus tried to write an Othello program in C++. It ended up buggy and the computer could only play random moves. Years later, with mechatronics skills, he turned that failure into Othellobot: a gantry robot that watches the board with a camera, picks its move and places clear tokens with a suction cup. The smart part is that it never flips a disc. Every cell has its own LED… |

Hugging Face's Reachy Mini Robot Gets $149 Wheels and NFC Hats That Swap Its Personality Pollen Robotics, the Hugging Face robotics team behind the open-source Reachy Mini desktop robot, has launched "Level Up", a set of add-ons that let the little robot leave the desk. Announced on 29 October, it adds a two-wheeled Hoverboard base, NFC hats that switch the robot's personality, and iOS and Android apps. What is new Hoverboard, $149 (pre-order): a two-wheeled base with soft… |

A 185 mg Insect-Sized Robot Took a Flyswatter Hit and 11,000x Its Weight, Then Flew Again Most insect-sized flying robots are lab pets: one crash into a wall and a rigid hinge or gearbox snaps. A team led by Yuan Zhu, Hanxiang Wu and Professor Qibing Pei at UCLA, with Wenzhong Yan at UC Davis has built one that shrugs it off. Their 185 mg robot, lighter than a fifth of a gram, took off again after being hit with a flyswatter and after being flattened under aluminium blocks weighing… |

A 1984 Tomy Omnibot Gets a Raspberry Pi 5 Brain and an AI Camera That Knows 80 Objects In 1984, Tomy sold the Omnibot as the robot butler of the future. It could roll around, play cassette tapes and carry drinks on a tray, but it had no real intelligence: everything came from a remote or a pre-recorded tape. Forty-two years later, maker Mario Cruz has given a donated Omnibot at Moonlighter FabLab in Miami the brain it was promised, using a Raspberry Pi 5, the Raspberry Pi AI… |

This Open-Source 1.2 m Humanoid Runs on a Raspberry Pi 5 and a Radxa CM5, and After a Year of Building It Is Now Walking in Public Most humanoid robots you see walking on stage are closed products with closed software. Asimov 1 is the opposite. Menlo Research, a team in Singapore, has published the full mechanical CAD, electrical schematics and PCBs, simulation models, firmware and walking policy for its 1.2 m, 35 kg humanoid, and on day 366 of the project the robot was out in public at the SWITCH event in Singapore,… |
