Cost-effective and compact: gearbox system for service robotics

ReBeL®: fully integrated single joints

With the ReBeL® series, igus® introduces for the first time low-cost robotics strain wave gears, with which 6 DOF robots, i.e. with six axes, can be implemented. With the modular ReBeL gearbox system, you can build a service robot yourself or buy one that has already been configured. What is special about ReBeL gearboxes is that the fully integrated individual gearbox contains a motor, a control system, and an encoder in a single component.

The ReBeL strain wave gear is fundamentally different from the previous robolink® worm gears: instead of stepper motors, it uses light, brushless direct current motors (BLDC motors). Add the motor controller, and you have a fully integrated strain wave gear. This type of motor is usually used in service robotics. The gearbox is constructed as follows:

A: output with encoder and mounting flange
B: tribologically optimised polymer strain wave gear
C: brushless DC motor (external rotor)
D: CAN-BUS motor driver board

Improve technology

25% lighter than conventional strain wave gears thanks to igus® high-performance polymers
fully integrated individual gearbox with motor, control system and encoder
Greater capacity thanks to the low weight of the multi-axis kinematic elements

Cost down

Start right away with robot kinematics thanks to fully integrated strain wave gears
Lightweight and thus energy-efficient

Proof

The outer contour and most of the mechanical components are made of polymers and are therefore cost-effective and lightweight.

Sustainability

Low Cost Automation products are completely maintenance-free
Lightweight components
igus® supports the circular economy of plastics and is investing in chemical recycling. Learn more about this topic at Plastic2Oil.

Buy service robots or build them yourself

With the joints of the ReBeL series you can build your 6 DOF ReBeL robot, or e.g. a 3 DOF Scara robot. In future, you will be able to order the ReBeL service robot from us as a ready-made complete system.
