Building a capable robot is only half of the battle. To take advantage of that robot, you’ll need a good way to control it. When it makes sense, you can pre-program movements. But when you want to control a robot in real time, you need a suitable controller. Conventional joysticks and gamepads don’t translate well […]
To give an electric car more range, you need a bigger battery pack. But that adds weight, so you need bigger motors and more battery capacity to compensate. This creates a vicious cycle and robot arms are susceptible to a similar problem. A robot arm needs to lift its own weight in addition to whatever […]
Robotic arms are versatile machines and are great for learning about principles of robotics or even doing useful work for hobbyists. That work might be picking and placing components on PCBs, packing boxes, or anything else you can imagine. But to perform that work well, the robotic arm needs more hardware than we tend to […]
Normally, robotic arms are controlled by a GUI running on a host PC, or with some kind of analog system that maps human inputs to various degrees of rotation. However, Maurizio Miscio was able to build a custom robotic arm that is completely self-contained — thanks to a companion mobile app that resides on an […]
As a maker, you probably have a third hand for your soldering station. They come in handy when you need to hold a component, PCB, solder, and soldering iron all at the same time. But an extra hand would be useful for a wide range of other everyday activities. That’s why this team of researchers […]
Would you like your own industrial robot arm, but don’t have tens of thousands of dollars to spend? You could instead build Giovanni Lerda’s KAUDA, a five-axis device that uses under 800g of PLA, an Arduino Mega, and other off-the-shelf parts. KAUDA utilizes servos to actuate the two wrist joints, along with a NEMA 17 […]
Robotic arms can be interesting, as are robots that roll around—especially on a semi-exotic Mecanum wheel setup. Dejan Nedelkovski’s latest How To Mechatronics build, however, combines both into one package. This project actually starts out in a previous post, where he constructs the moving base with Mecanum wheels, enabling it to slide and rotate in […]
With the lack of people capable of turning written or spoken words into sign language in Belgium, University of Antwerp masters students Guy Fierens, Stijn Huys, and Jasper Slaets have decided to do something about it. They built a robot known as Aslan, or Antwerp’s Sign Language Actuating Node, that can translate text into finger-spelled letters and […]
Using an Arduino Uno along with a Raspberry Pi for control, hacker “HomoFaciens” came up with this clever delta-style robot. If you were going to make a robot with five servos, many Makers would make a robot arm with them and call it a day. HomoFaciens, however, who is known for making amazing machines with minimal […]
Need a hand? The UFACTORY team has got you covered with the uArm Swift, an open-source robotic assistant for your desktop. The four-axis uArm Swift is a smaller and sleeker version of the company’s original device from 2014. Based on an Arduino Mega, the robot is capable of lifting 500 grams (1.1 pounds) with a working range of 5 to 32 centimeters (2 to 12.6 […]
