Arduino based Human Following Robot 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…

Engineer Builds Self Driving Mini Fridge Robot Engineer Turns Mini Fridge Into a SLAM-Guided Tank Robot You'd Have to Chase for a Cold Drink

Engineer Dorian Todd has built a self-driving mini fridge on tank treads that can autonomously chase or flee a person and reward them with a cold drink if caught. The project replaces the fridge's standard base with a tracked drivetrain powered by Repeat Robotics Ultra Mark II brushless gear motors designed for 12 lb combat robots. Todd 3D scanned both the metal tread assembly and the…

Petoi Unveils Four Servo Open Source Quadruped Robot Quaddle Is an Open-Source Desk Robot That Can Move Omnidirectionally With Just 4 Servos

Petoi, the team behind the open-source Bittle and Nybble quadruped kits, has opened early access for its next robot, Quaddle. The company describes it as a four-servo quadruped capable of walking, strafing sideways, and spinning in place, a claim that stands out mainly because of how few actuators it uses to pull it off.

Most legged robots that can…

ESP32 Powered Spider Man Web Shooter Prototype Maker Builds an ESP32 Powered Spider Man Web Shooter in This Brand New DIY Project

YouTuber Plentiful Props 3D has developed a functional Spider Man-inspired web shooter that combines custom electronics, 3D-printed parts, and a servo-actuated spray mechanism to fire web-like strands from a wrist-mounted wearable. The project uses an ESP32-S3 Mini development board mounted on a custom PCB to control the firing mechanism. According to the creator, the electronics package…

Build an Interactive Robotic Arm using PIC Microcontroller How to Build an Interactive Robotic Arm using PIC Microcontroller?

Robotic arms are widely used in industrial automation, research, and educational projects. Building and controlling one is a great way to learn the fundamentals of embedded systems, motion control, and robotics.

In this project, we will design and build a 4-degree-of-freedom (4-DOF) robotic arm controlled…

A DIY Mushroom Robot Moody Mush: DIY Interactive Mushroom Robot That Follows Your Touch

Moody Mush is an interactive, mushroom‑shaped robot built by SayaNIGHT. It has three modes of operation. In Mode 1, it functions as a desk lamp; the LEDs and cap (the head portion) are controlled with an IR remote. In Mode 2, the LED colors are adjustable with the same remote, but the robot also reacts to touch. Different movements and sounds occur depending on the type of touch (a short touch…

DIY Bipedal Robot Walks and Balances With Just Five Servos Five-Servo Bipedal Robot Walks and Self-Balances on a Budget

A maker has built a two-legged walking robot using just five RC servos, an ESP32 microcontroller, and 3D-printed parts, making it the third entry in a series of accessible open-source robot designs. The project follows earlier builds in the same series: a mini robot dog and a hexapod. The creator set two design requirements: the robot must actively balance as it walks, and it must lift its…

Making A Functional Arm Cannon For Bungie Engineering a Functional Arm Cannon for the Makers of Halo

A maker built a real, functional replica of the arm cannon belonging to Vandal, a character in Bungie's video game Marathon, for use in a commercial. The builder had 18 days to complete the entire project.

The build was divided into two main subsystems: a forearm clamshell mechanism and an internal barrel assembly. Bungie provided game asset mesh files for reference but, because the…

Clock With Water as Pixels Clock Uses Water Bottles as Pixels With Membrane Pumps and Servos

Maker Strange Inventions has built a water-based digital clock in which 60 small bottles act as individual pixels, collectively forming numerals to display the time. The bottles, sourced at 10 cents each, brought the total project cost to approximately $580. Each bottle is filled or emptied with dyed water to switch its pixel state on or off, with the display controlled by a microcontroller…

Conversational Baymax Robot with Animatronics and AI Integration Conversational Baymax Robot with Animatronics and AI Integration

Maker Brae Barnes is developing a conversational Baymax-style robot that combines animatronic motion with an AI-driven speech system. The current prototype focuses on the head assembly, featuring articulated neck movement, blinking eyelids, and the ability to respond to spoken input using a speech-processing pipeline. The goal is to create a robot that not only talks but also conveys…

FPV Jeep with Servo-Based Camera System Powered by SpeedyBee F405 Mini RC Jeep Uses a Servo-Powered Camera Rig for True Driver POV

What if an RC car could make you feel like you’re actually sitting inside it? That’s exactly what creator kpopRC has built with his latest FPV Jeep crawler. Instead of a fixed camera, the system uses a servo-powered “lean-out” rig mounted in the driver’s seat position. This allows the camera to physically extend out of the window and move with pan and tilt controls giving a true driver’s…

Desk-Sized Marble Pixel Clock Built by DIY Maker A Desk Clock That Uses Marbles to Tell Time

A neatly designed electromechanical clock shared on YouTube is drawing interest from hobbyists and electronics enthusiasts alike. The project is inspired by the marble clock concept originally created by Ivan Miranda, but the creator redesigned it into a smaller version that can easily fit on a desk. Instead of simply copying the original build, the maker simplified the structure while keeping…
