A retrofittable compensation module with sensors and kinematics in six independent degrees of freedom expands the field for factory automation
Passive and active compensation during joining processes with minimal tolerances
Tactile handling: Touch, grip and place objects safely and flexibly
Quick teaching: automated and manual
Higher productivity thanks to seamless process monitoring and correction

Small component, big effect: The Smart Flex Effector, a new, sensor-based compensation module from Bosch Rexroth, gives robots and Cartesian linear systems human-like sensitivity and thus offers new opportunities for factory automation. Processes which are difficult to manage can now be automated, optimized and monitored through simple retrofitting. Thanks to a kinematics system that works independently in six degrees of freedom, the tactile all-rounder with sensitive touch precisely records the position of the work piece and passes the information to the robot control unit for active compensation purposes. Typical applications are joining processes with minimal tolerances, complex assembly work or difficult handling tasks. Errors and rejects are minimized and teaching and commissioning can be carried out more easily and quickly.
The Smart Flex Effector is designed for handling loads of up to 6 kg. For machine manufacturers and users, it opens up a wide range of new applications which were difficult or not possible to realize with previous equipment such as passive compensation units, force torque sensors and visual systems. The applications range from process automation and quality monitoring to teaching and the controlled handling of objects.
Quantum leap in process automation
With its differentiated kinematics, the tactile all-rounder is able to correct processes with great complexity and tight tolerances, for example in the case of positional deviations between the tool and the work pieces or in complex joining processes with minimal tolerances. Thanks to this tactile sensitivity, tasks that were not automatable can now be performed by robots.
Quicker teaching
In another area, the Smart Flex Effector also reduces the time previously needed for teaching processes. Thanks to the 6D position recording, the robotic control system can read the exact coordinates for gripping and placing points directly. Repeated learning during operation is therefore possible in an automated manner. Robots can also be taught manually – simply by moving them into position by hand.
Sensitive handling of objects
Even during sampling, the Smart Flex Effector can be used to recognize positional deviations and, with the help of the sensor system, to determine the exact position of the object. The robot accurately picks up assembly or handling objects, positions them in a controlled manner and places them reliably or sorts them. Even parts made of glass or other sensitive materials can now be handled safely. In order to ensure maximum productivity, the compensation module can be actively moved into the zero position and electromechanically locked for fast transfer runs.
Improved quality thanks to transparency
As part of process monitoring, the Smart Flex Effector makes not only documentation easier. Quality too can be improved as deviations are recognized immediately and either corrected or reported to the control system. This avoids errors and unnecessary costs owing to rejects or follow-up work.
High connectivity, easy installation
The Smart Flex Effector offers an RS-485 interface as well as an I/O interface for exchanging data. Installation is extremely easy: For a passive compensation function, the Smart Flex Effector is simply screwed to the robot flange and the gripper. The locking function and data transmission are available as soon as the unit is connected to the power supply and the control system.
