Researchers from Cornell University and the University of Pennsylvania have created a lifelike robotic lionfish with a circulatory system. That circulatory system enables the fish to circulate synthetic blood throughout its body. The blood is a liquid triiodide cathode, which circulates past zinc cells submerged in an electrolyte. As the zinc oxidizes, it releases electrons,…
Little Flash is a 3d printed robot powered by ultracapacitors. To prevent getting stuck, she uses a bump switch, motor overcurrent detection and random path adjustments. Supercapacitors are intriguing power sources because they can store and release charges in an instant. This device uses a pair of continuous rotation-modded servos to move about for roughly…
Omni Wheel CNC plotter is a device with four wheels that allow sliding motion in the X/Y plane courtesy of their perpendicular rollers. to make it more interesting, the maker has attached a pen, along with a servo-based lifting mechanism, turning this robot into a free-range plotter. Omni-wheels only have traction in the direction of…
Taylor Tabb, Mitchell Riek, and Evan Hill have created the perfect device to create the best grilled cheese it possibly can! “Our goal was to make an easy snack even easier. The design combines 7 individual subsystems enabling the assembly, cooking, and serving of a perfect, repeatable, tasty grilled cheese.” Cheeseborg has been designed to…
Some days may be hard to wake up, other days it can be really hard…but now, thanks to Nikodem Bartnik it’ll be easier, but maybe more shocking! He has created an Arduino-powered mobile robot that scoots your phone out of the room in the morning, forcing you to get out of bed and chase it…
If you need a robot to traverse piping systems, this arduino powered six-wheeled robot could be just the thing! Pipeline systems deteriorate progressively over time through various means. Pipeline inspection robot are designed to remove the human factor from labour intensive or dangerous work environments and also to act in inaccessible environment. However, if you…
Walking robots come in many forms, and each presents their own unique challenges. Bipedal style locomotion is considered particularly difficult to do well, however designs with more legs offer certain advantages. Hexapods offer the possibility of keeping several legs on the ground while others move, providing a useful degree of stability. This type of robot…
The OpenLH is based on the uArm Swift Pro open source robotic arm and allows creative exploration. 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 just .15 microliters….
Mug-O-Matic is a 3-axis drawing robot that can customize coffee mugs. It uses markers to draw anything you want on a coffee mug via manual controls, calculated algorithms, or even g-code. The mug can be washed clean with warm soapy water or the drawing can be made permanent by baking it in the oven. In its…
Instructables user MusaW has recently released a detailed guide to create a four leg (quadruped) robot using SG90 servo with servo driver and all controlled using WIFI Web server via smartphone browser: the total cost of the robot, including electronics and 3D printed components, is around US $55. There is a lot of NodeMCU variant in…
“I built this costume for the Edmonton Comic Expo 2018, but also because I have kids, nieces, and nephews, and a costume like this scores mega points, doesn’t it?” This amazing creation requires both a child and an adult to make it work. The suit is beautifully designed by creator Gridlock Cosplay, and features an…
I really like the crappy sound of those 80s toy keyboards. Unfortunately, I am a lousy live keyboarder and I only have so many hands. So I thought about adding MIDI capability to my good old Casio SA-21. The simplest way to do this is obviously building a robotized hand with 8 servo motors controlled…
