No movement without robot control! Because only the necessary computing power ensures that the links of a robot can move reproducibly.
Integrated: More and more robot arms have an integrated controller in the base of the robot to save valuable space.
External: There are DIN rail versions for integration into existing control cabinets or stand-alone solutions as a separate control cabinet.
In either case, check that the controller is compatible with your overall system and fits the performance requirements.
Programming the robot controller
The goal of low cost robotics is not only to reduce costs, but also to make extensive programming knowledge, which has to be paid dearly, a thing of the past. Depending on the robot manufacturer, sample programs or free software, as with igus, can simplify the introduction to programming.
