AROS joints are all-in-one actuators range to set your robot in precise motion. Market leading torque/weight ration together with integrated brakes and EtherCAT controller assure compact solution with needed payload and speed.

Integrated actuator


  • Motor - high-torque brushless motor provides power to the robot.
  • Gear - strain wave harmonic reducer offers accuracy, torque and desired speed.
  • Brakes - electromagnetic power off clutch brakes ensure safe payload handling.
  • EtherCAT Controller – drive actuator in real time with high-speed communication protocol.
  • Encoders - pair of 19-bit absolute multiturn encoders control rotation accuracy on both shafts.
