igus ReBeL lightweight cobot

To enable interactive robotics concepts to be implemented quickly, igus has developed the latest generation of the ReBeL — a lightweight plastic robot that has a fully integrated tribo strain wave gear with motor, encoder, force control and controller. Electronic components in the fully integrated strain wave gear allow human–robot collaboration (HRC) to be possible. This is because the encoder technology enables forces and torque to be determined and limited via the motor current in combination with the angle measurement. For this, igus relies on a double encoder, in which a measurement is carried out in front of and behind the joint. This detects forces and torque levels and responds accordingly.

The use of plastic in the robot results in a compact, lightweight design. It has a net weight of less than 10 kg, and supports a payload of 2 kg with a reach of 700 mm.

The robot can be tested and operated easily, according to igus, via free control software: it is easy to define and simulate the movements of the robot quickly, which should save on commissioning costs and lessen the dependence on integrators. Those who require further support can also make use of the igus RBTXpert service, which helps in the selection of the right automation solution.
