Make It With Matty

After building my original beginner-friendly 5-axis Arduino robot arm , I wanted to go back to the project and make a few improvements. I didn't want to completely redesign the robot. The original arm was intended to be relatively simple to build, understand and modify, so I wanted to keep that idea. Instead, this version concentrates on two major upgrades: A stronger MG996R servo for the shoulder joint A new Arduino program that can record a sequence of movements and replay them automatically I also had to modify several of the 3D-printed parts to accommodate the larger shoulder servo. Updated Shoulder Joint The result is essentially Version 2 of my original robot arm. New to the project?

MG996R Shoulder Servo The original arm used an MG90S servo at the shoulder , this servo was struggling with the weight of lifting objects. The torque...

Fully Assembled Robot Arm Building a robot arm might sound like an ambitious first robotics project, but it doesn't have to be. With a 3D printer, an Arduino Uno and a handful of affordable hobby servos, you can build a fully functional five-axis robot arm while learning the fundamentals of mechanics, electronics and programming. This project was designed with beginners in mind. There are no custom PCBs, expensive components or specialist tools required. Instead, the focus is on building something that is easy to assemble, easy to understand and, most importantly, easy to improve. Like any engineering project, this robot didn't work perfectly the first time. In fact, solving the problems taught me just as much as building it. Rather than hiding those mistakes, I've included them here so you can avoid the same issues when building your own.           By the end of this guide, you'll have everything you need to build your own robot arm and a solid foundation ...
