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… |

ROSCon Returns to Bengaluru & Circuit Digest Joins as Media Partner ROSCon India 2026 will take place from 2-4 December at the JN Tata Auditorium, IISc Bengaluru, and Circuit Digest will be there as a Media Partner. If you work with ROS, build robots, or are just getting into robotics, this is one to know about. It's a gathering of India's ROS community, and it's been growing every year since its first edition in 2023. The 2025 edition in Pune recorded… |

Microchip Enhances Robotic Tactile Sensing with High-Speed Capacitance Digitizer Reliable robotic manipulation requires more than vision, particularly when handling soft, fragile or irregular objects. Cameras can locate an object, but tactile sensing provides the contact information needed to determine how firmly it is held and whether it is beginning to slip. Microchip Technology (Nasdaq: MCHP) has introduced the ATFCD52 high-speed capacitance digitizer to convert signals… |

This Open-Source ESP32-S3 Stepper Driver Cut Joint Error From 0.065 to 0.014 Degrees A stepper motor can reach its target while the robot joint it drives is still in the wrong place. That gap comes from backlash in the gearbox, and it is the reason cheap 3D-printed robot arms feel sloppy. Arctos Robotics, the maker behind the open-source Arctos arm, built CLMD, an open-source ESP32-S3 stepper driver that reads a second encoder right at the gearbox output and corrects the joint… |

This 18-Servo Hexapod Changes Its Walk Mid-Stride, With All the Leg Math on One ESP32-S3 Most hobby hexapods walk by playing back a fixed sequence of leg moves, which is why switching gaits usually means stopping first. The hexapod built by ForgeVolt does not stop. It blends from a fast tripod walk into a tetrapod or ripple gait while it is still moving, leans into curves, and keeps its body level when the floor tilts under it. All of the leg math runs on one ESP32-S3, and the… |

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… |
