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… |

Phantom Twist: The Spinning Drone That Hides in Plain Sight Northwestern University engineers have unveiled Phantom Twist, a groundbreaking low-visibility UAV that exploits human visual perception to hide in plain sight. The drone spins its entire body at up to 25 rotations per second using a single motor and counter-rotating propeller system. Unlike traditional quadcopters with stationary bodies, Phantom Twist has no fixed… |

DIY LEGO RC WALL-E Robot Using ESP32 and a PS4 Controller The main part of the project is a LEGO RC WALL-E itself. He initially planned to use a FlySky controller and its remote, but later switched to a PS4 controller as it is much more compact and offers more controls. He used an ESP32 as the receiver. After some research, he decided to use the Bluetooth functionality of the ESP32 for communication. Two N20 motors along with an L298N motor driver… |

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… |

Supercapacitor-Powered Electric Wind-Up Plane We have all seen old rubber band wind-up planes built by crazy makers. Tom Stanton, a youtuber, just turned one into a 21st century electric wind-up plane powered by a supercapacitor. He is an engineer and a maker who loves to mix physics, 3D printing and clean energy storage. Instead of winding up a rubber band, he used his hand crank generator to charge a supercapacitor. This stored energy… |
