After some experimenting, he came up with a smooth moving robot arm with four steppers controlled from an Arduino Mega and A4988 stepper motor drivers.

Stepper motors are simple and cheap to use, and you don't need to have a fully closed-loop controller to use them accurately. Servomotors are much faster, but for guaranteeable positioning accuracy, ...

To achieve CNC functionality, machine shops can convert hand-wheel controls to automated controls with stepper motors. The process depends on the machine type and layout … CNC machine centers offer ...

Due to this fine level of control, stepper motors are required in any applications where there needs to be an exact movement such as 3D printers and CNC machines (or robots).

If you are building a project that needs to control stepper motors wirelessly you might be interested in a new piece of hardware created by the team at Good Robotics which takes the form of the ...

In this paper, the authors focus on designing and controlling an articulated 3-DOF robotic arm using LabVIEW and NImyRIO. Now-a-days, robots have been used in common places of manufacturing and ...
