Collaborative robots (cobots)

Collaborative robots or ‘cobots’ are making the world of human and robot interaction within a shared space rapidly become the norm. Human-robot interactions can now range from simple coexistence and cooperation to full collaboration. Currently most cobots are relatively small, with a maximum payload capacity of between 0.5 to 20 kg while maintaining a good reach and without sacrificing accuracy, speed or repeatability. They often operate with 6-degrees of freedom (6DoF), requiring a separate brushless DC motor on each of the 6 axis. While powered from a mains supply, cobots motors use either a 24 V or 48 V supply.
