Wire kinematics offer a larger robot working area
Researchers at the Fraunhofer IPA institute have come up with an alternative robot technology for applications that require short cycle times over large transport distances at high speed. With wire kinematics, they have developed parallel wire robots that they say pave the way for an innovative concept for automation solutions to handle extreme requirements.
Compared with conventional industrial robots, the IPAnema wire robot boasts a large working area (2x2x1.5m), high speeds (up to 10m/s), extreme acceleration (greater than 10g) and a wide payload range from 1kg to 400kg.
These characteristics can also be adjusted in line with a specific problem: The working area can be up to 100 m x 100 m x 30 m depending on the application. The efficient transfer of force through the wires means each wire can support a payload of several tonnes.
The robot is controlled by a real time-capable NC control system which can be programmed easily via the tried-and-tested G-Code (DIN 66025). A programmable logic controller (PLC) can be connected as an option, enabling existing plant to be integrated easily.
Additional wires can easily be inserted into the wire robot to increase safety in the event of individual components failing in safety-critical applications, such as lifting heavy and/or sensitive loads. Alternatively, the working area can be enlarged in this way.
