Low-cost robotic joint for service-robotics tasks

Injection-molded components make the robolink® ReBeL joint a cost-effective flyweight.

With the ReBeL series, igus® introduces for the first time low-cost robotics strain wave gears at HMI 2018, with which 6 DOF robots, i.e. with six axes, can be implemented. This prototype was created in collaboration with the company Commonplace Robotics GmbH and is fundamentally different to the previous robolink® joints: Instead of stepper motors, light, brushless direct current motors (BLDC motors), which already belong to the state of the art in service robotics, are used.

All the advantages at a glance

  • Cost-effective joints for up to 6 DOF
  • Most of the joints are made of polymers and are therefore cost-efficient and light
  • Motors, control technology and cable guidance built into the housing
  • Joints are suitable for service-robotics applications
  • Brushless direct current motors instead of stepper motors

No control cabinet necessary

Due to their small size, the space-saving BLDC motors can be installed in the strain wave gear of a robolink® joint. The control electronics system is also built into the axes and thus renders an external switch cabinet superfluous. Cable guidance can take place in the arm, the result being that the outer contours of the robot are smooth. There are also plans to equip the new joints in future with absolute encoders that facilitate your work by saving the position of the arm in the event of a power failure.

Areas of application for the robolink® ReBeL

robolink® ReBeL joints can be used for tasks in the workplace and in the private sector. The ReBeL joints are particularly suitable for mobile applications in which a robotic arm is mounted on a moving platform. The following application areas, for example, are conceivable:

Mobile applications

Combination with the Alexa voice assistant

Collection and delivery services

Pick-and-place tasks

Loading and unloading dishwashers
