He has made a robotic arm called dARM. It is a robotic arm with 6 degrees of freedom, and most of the parts are 3D printed. He has used brushless DC motors for its working rather than servo motors.

This is today's industry standard for motors on RC applications, an efficient, powerful, and durable brushless DC motor, as compared to conventional brushed motors. But then, there are pros and cons ...

The choice of motor is important in robotics, as it influences how well the robot will perform in terms of efficiency and functionality. Brushless DC motors (BLDC) are the ever-efficient and lifetime ...

Sensorless brushless DC (BLDC) motors represent a significant advancement in electric motor technology. Unlike traditional brushed motors or sensored BLDC motors, they operate without Hall effect ...
