The Powerball concept from SCHUNK, takes another giant step forward: This fifth generation lightweight arm presents an especially compact and flexible aid for stationary and mobile applications in service robotics and industrial handling. The module features a weight/payload ratio of 2:1 and is one of the most powerful lightweight arms in the world. At a dead weight of 12 kg, it can dynamically handle loads of up to 6 kg, and has a gripping radius of more than 700 mm. Due to the compact design of the wrist joint, the arm can be easily maneuvered in tight spaces. Its excellent repeat accuracy of 0.06 mm provides for high process stability for demanding measuring and testing tasks. Also, the intelligent design prevents dangerous crushing and shearing movements, making it safe to use around people as well.


Central elements of the lightweight arm are three compact ERB Powerball modules, which combine the movements of two axes. The entire electronic control and regulation circuitry is integrated in the joint drives. Position, speed, and torque can be flexibly regulated. An innovative quick-change system with integrated signal feed-through allows for fast and easy commissioning of the Plug & Performance gripping system. Since the supply lines for gripper and tools are completely within the module, there are no interfering cables on the peripheral devices. Due to the integrated intelligence, universal communication interfaces, and cable technology for data transfer and power supply, the arm can be quickly and easily integrated in existing control concepts. The manipulator is supplemented by an industrial robot controller with an integrated CoDeSys PLC. Teaching and instruction is made easy by means of a hand-held control panel with a touch-screen display.

24 V DC supply voltage enables mobile use as well as use at changing locations. Consistent lightweight construction and the state-of-the-art torque motors keep the energy demands of the lightweight arm down to an average of 80 W. That lowers energy costs, provides for longer work periods when using rechargeable batteries, and also allows the use of small-format batteries. With a price well below any other lightweight arm, and has the potential to pave the way for broad-scale applications.

Model TR1 Tru-Trac

Model TR1 Tru-Trac

The Model TR1 Tru-Trac® linear measurement solution is a versatile option for tracking velocity, position, or distance over a wide variety of surfaces. An integrated encoder, measuring wheel, and spring-loaded torsion arm in one, compact unit, the Model TR1 is easy to install. The spring-loaded torsion arm offers adjustable torsion load, allowing the Model TR1 to be mounted in almost any orientation - even upside-down. The threaded shaft on the pivot axis is field reversible, providing mounting access from either side. With operating speeds up to 3000 feet per minute, a wide variety of configuration options - including multiple wheel material options - and a housing made from a durable, conductive composite material that minimizes static buildup, the Model TR1 Tru-Trac® is the ideal solution for countless applications.
