The mechatronic SCHUNK SVH 5-finger gripper hand designed for service robot applications, is ready for series production. After an intensive concept phase, SCHUNK, the competence leader for clamping technology and gripping systems, has added the anthropomorphic gripper hand to the standardized line of modules for mobile gripping systems. On option, it is available as a left or right hand. The size, shape, and agility are amazingly similar to the human model. With a total of nine drives, the five fingers can execute diverse gripping operations. Elastic surfaces on the end finger joints ensure a reliable grip on objects.

Moreover, numerous gestures are possible, which facilitate visual communication between man and service robot, and increase acceptance for use in a human environment. Complete integration of the control and power electronics in the base of the hand allows especially compact solutions. Control is possible via either Profibus or CAN-Bus. Defined interfaces enable connection of the SCHUNK SVH to standard industrial and lightweight robots. For use in mobile applications, the power supply is designed for battery-compatible 24 V DC operation.

The mechatronic SCHUNK ERS rotary module allows multiple applications in confined spaces. On request, it is available in a dust- and splash-free version (IP54), and with a pneumatic-electric rotary feed-through.

When competing for the highest speed, flexibility, reliability, and efficiency in production automation, mechatronic modules are rapidly gaining in importance. The SCHUNK ERS rotary modules were developed for rotary movements in the medium load range. The currently most compact mechatronic rotary module on the market is available in unit size 170 with a height of 66 mm, achieving a nominal moment of 5 Nm, and a maximum moment of up to 17 Nm. It is used for implementing flexible and compact system concepts.

The core piece is a torque motor with a hollow shaft. It is light-weight and compact, and is absolutely wear-free, making it very reliable. It can endlessly turn up to 250 rpm to any intermediate position at a repeat accuracy of 0.01°. In contrast to rotary modules with a conventional servo motor, the ERS has no additional interfering contours and no elasticity. This long-lasting module from SCHUNK, the competence leader for clamping technology and gripping systems convinces with high acceleration, swiveling speed, and precision. On request, an integrated pneumatic holding brake ensures that individual positions can be reliably fixed. The center hole allows feed-through of cables, workpieces or the use of a camera.

In order to feed compressed air or signals without hoses or cables through the module, the compact module is also available in a version with pneumatic-electric feed-through, by using a slip ring or air channel of up to eight electric signals (24 V DC/2 A), and a fluid with a pressure of up to 8 bar. For feed-through of higher currents and voltages, slip rings can be also combined. The SCHUNK ERS is available in three sizes with outside diameters of 135, 170, and 210 mm. The version with feed-through is available with outside diameters of 170 and 210 mm. In order to achieve the highest possible flexibility for the control and regulation strategy, it can be actuated with the SCHUNK Motion Controller ECM (48 V version) or a common standard. Every unit size is also available as a dust and splash-proof IP 54 version. Supply and actuation of all the ERS rotary modules is carried out by a standard plug (M9/M17).

Schunk has developed EGL 70 mechatronic parallel gripper, which combines power and intelligence, with variable gripping force between 50 and 600 N, specifically developed for industrial applications. Since the finger position, closing speed, and gripping force are freely programmable within a maximum stroke of 48 mm per finger, diverse components with a weight of up to 3 kg can be precisely handled in force-fit gripping. The gripper fingers can be prepositioned to reduce cycle times.

The entire control and power electronics of the EGL are integrated to save space and to allow decentral operation and even mobile use, thanks to the 24V DC operating voltage. Standard Profibus DP and CAN-Bus interfaces allow fast and easy integration in higher level system controllers. The gripper also features a USB-port as a service interface. A brushless servo motor ensures continuous and reliable operation with no maintenance required.

To maintain the position in the event of a power outage the gripper features an electrically operated brake. Since the EGL fulfills industrial standards and the basic version is connected only by means of industrial connectors, installation time is reduced to a minimum.

The powerful mechatronic gripper is compatible with the world’s most extensive standardized line of modules for gripper systems from SCHUNK. In combination with quick-change systems and other robot accessories it can significantly increase the flexibility and efficiency of handling processes. It is ideal for diverse applications in the field of industrial assembly technology, mechanical engineering, and lab automation.
