Low-cost joints for service-robotics tasks

The new robolink ReBeL joints can be used for robotic tasks in the workplace and in the private sector.

The robolink ReBeL joint is a cost-effective flyweight with which 6 DOF robots, ie 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) are used.

The space-saving BLDC motors can be installed in the strain wave gear of the 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.

In this video we see how they are particularly suitable for mobile applications in which a robotic arm is mounted on a moving platform.
