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… |

He Built a PC Hardware Monitor That Looks Like a Four-Gauge Aircraft Instrument Panel Old aircraft panels still look better than any flat graph on a monitor. Reddit maker Night-Caps put that look on his desk: four aircraft-style gauges driven by an Arduino that reads live PC hardware data from HWiNFO over serial. The needles move with CPU and GPU temperature, load, GPU power and RAM, and the post landed near the top of r/arduino with about 750 upvotes. Switec steppers… |

This DIY Wax Motor Held Its Position to Within 5 Microns for 12 Hours, Just by Melting Wax Wax motors are the quiet actuators inside washing machine door locks, radiator valves and car thermostats: heat a block of wax, it melts and expands, and that expansion pushes a piston. Nobody thinks of them as precision parts. BubsBuilds built his own "waxtuator" to find out how precise one could be, and with careful temperature control it held a gap of less than 5 microns for twelve hours.… |

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 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… |

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… |

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… |

Pac-Man, Space Invaders and Manic Miner Run on a Plain Arduino Uno at 50 fps, With Two Resistors for Video and No Framebuffer An Arduino Uno has 2 KB of RAM, 32 KB of flash and a 16 MHz 8-bit ATmega328P. That is less memory than the 1982 ZX Spectrum had, and nowhere near enough to hold a frame of video. Even so, Smashcat has built a game engine that runs full arcade-style games on it at a locked 50 frames per second, straight to a TV over composite video made with just two resistors. It now runs four games: Manic… |

Arduino's 16 GB VENTUNO Q Runs a 744-Billion-Parameter AI Model From an SSD, and It Took 7 Minutes to Name Three Planets Large language models with hundreds of billions of parameters normally live in data centres, on servers with far more memory than any single-board computer. So it is a surprise to see one answer a question on an Arduino. In a project published on Arduino Project Hub, Jim Bruges ran GLM-5.3, a 744-billion-parameter model whose files take up about 419 GB, on an Arduino VENTUNO Q with just 16 GB… |

Two Eyes, One Tiny Chip: This Open-Source Board Computes Stereo Depth So Your Arduino Doesn't Have To Hardware hacker machinehum (Rootkit Labs) has built 4reel, a small open-source stereo vision board that gives robots depth perception without a Raspberry Pi or a PC riding along. Two OV9281 global-shutter cameras sit at either end of the PCB, and the depth maths runs on the board's own Rockchip RV1103 chip. Your Arduino or ESP32 just reads the results over UART. Powered by a single-core 1.1… |

This Arduino UNO Q Headband Uses 13 Vibration Motors for Screen-Free Awareness Through Haptic Feedback Maker pasquale887 has developed HaloSense V1, a wearable haptic headband that helps users sense the direction of people and objects through vibrations instead of looking at a screen. The headband has 13 small vibration motors arranged around the forehead. When a person or target is detected in a particular direction, the motor in the corresponding position vibrates, helping the wearer… |

Maker Builds a Linked Portal Illusion Using Arduino Uno R4, Flywheel Launcher, and ToF Distance Sensors A maker from the youtube channel James' Programming has recently built a linked portal illusion using Arduino, 3D‑printed parts, and a custom aluminum frame. The setup uses two identical “portal” frames facing each other: when an object is thrown into one, it appears to instantly emerge from the other, creating a convincing real‑time portal illusion without any video tricks. … |
