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
Joints are mostly made of polymers and are therefore cost-effective and lightweight
Motors, control technology and cable guidance built into the housing
Joints are suitable for service robotics applications
Brushless DC motors instead of stepper motors
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.
robolink® ReBeL joint with BLDC motor and strain wave gear
robolink® ReBeL joints can be used for tasks in the workplace and private sector. The ReBeL joints are particularly suitable for mobile applications where a robotic arm is mounted on a moving platform. The following examples are typical areas of application:
In combination with the Alexa voice assistant
Collection and delivery services
Pick & place tasks
Loading and unloading dishwashers
