If you have to do a lot of drawing on a whiteboard, you also have to clean it. Why not have a robot do this instead? That’s the idea behind Wipy, an Arduino Uno-based robot that uses magnets to stick to the board, along with grippy wheels and motors to power across your scribbles. Wipy […]
Do you like plants, but not so much tending to and watering them? If that sounds like you, then you might be interested in your own CNC growing machine. The system—created by 15-year-old maker “daily3dprinting”—is controlled by an Arduino Uno, and uses a single stepper motor to pull a watering head into position based on […]
Would you like a dog? Would you like a robot dog? If so, then this build by Michael Rigsby could be a great starting point. Rigbsy’s robotic pet features four servo-driven legs, with two-axis shoulder movement, as well as an articulated knee joint. As seen in the video below, it’s capable of picking itself up […]
When we last saw this omni robot by Jeremy S. Cook, it was lurching around under Arduino Nano and Bluetooth command. After much work, he finally has it to a state where it rolls nicely on a flat surface—even carrying a little strandbeest at just after 8:30 in the demo video. The biggest revision for […]
Normally, boiling an egg involves heating water in a saucepan, then dropping an egg inside to be properly heated. James Bruton, however, now has a bit of help in the form of his breakfast-making robot. The device uses two servos, along with a motor/encoder/screw assembly to rotate and lower the egg into place. It then […]
If you’ve ever been to an escape room, you’ve undoubtedly had to deal with a wide variety of puzzles that you have to solve in order to get out of the “prison” that you’ve willingly thrown yourself into. Beyond the puzzle that you’re trying to decode, the mechanisms used can be extremely clever, and coming […]
If you’d like an easy way to accomplish repetitive biological experiments, the OpenLH presents a great option for automating these tasks. The heart of the system is the Arduino Mega-controlled uArm Swift Pro robot, which is equipped with a custom end effector and syringe pump. This enables it to dispense liquids with an average error of […]
Six-legged robots are nothing new, but if you’d like inspiration for your own, it would be hard to beat this 22 servo-driven, 3D-printed hexapod from Dejan at How To Mechatronics. The ant-inspired device features three metal geared servos per leg, as well as a pair to move the heat, another for the tail, and a […]
Omni wheels are devices that look like wheels with extra rollers positioned along their circumference. This allows robots to move forwards and backwards, as well as slide and spin depending on how the wheels are powered. Maker Jeremy S. Cook decided to create his own version, and after some consideration and careful design work, constructed […]
While you may not give soda bottles much thought beyond their intended use, researchers in Germany and the U.S. have been working on a way to turn empty bottles into kinetic art. The result of this work is a program called “TrussFormer,” which enables one to design a structure made out of soda bottles acting […]
