Printed Robotic Arm Pumps Up With Brushless Motors

Summary
DIY robotics enthusiast JesseDarr has developed a new robotic arm that they say has more capability and strength than previous home-build arms thanks to its use of ODrive S1 controllers and brushless DC motors rather than the servos commonly used in the DIY community.
The arm, known as dARM (dynamic ARM for Robitic Mischief), is a totally modular unit that uses eight ODrive controllers, connected via a CAN bus to a Raspberry Pi 4B, to control three different types of brushless DC motor.
Jesse says the design is capable of lifting a 5lb payload in a horizontal position, and offers documentation on GitHub that includes assembly instructions, a bill of materials and guidance on setting up the software environment.
