### AI overview

Arduino Blog describes Kelton Serra's redesigned robotic arm, which uses puppet-style control through potentiometers, an Arduino Nano ESP32, servo motors, and a servo driver board. The redesign aims to make the arm more affordable, easier to build, and better performing, with 3D-printable parts and upgraded wrist and gripper mechanics.

### Source excerpt

Robotic arms are extremely versatile, which is the entire point. But that versatility comes at the cost of complexity when it comes to programming and control. A few years ago, Kelton Serra from the Build Some Stuff YouTube channel simplified the situation by giving his custom robotic arm a puppet-style controller. Now he's back with [...] The post Redesigning a popular robotic arm appeared first on Arduino Blog.
