Use Cases robolink
The igus robolink robot arms in combination with the CPR modular control are intended to solve small automation tasks in manufacturing, research and development, or in education areas.
See the igus robolink page for details on the available versions.
|5 axis small version||5 axis big version|
|Reach*||600mm (450mm)||750mm (580mm)|
|Joint velocities||max 45-60°/s||max 45-60°/s|
*Reach: Approximate values: XXXmm fully extended; (XXXmm) when gripping objects from above. To grip an object from above, the "hand" usually has to be perpendicular to the surface, hence the reach is shorter. Also the quality of the motion is better when the arm is not fully extended.
**Repeatability with identical load.
- Repeatability: better than 0.5 mm with identical load.
Repeatability is the deviation in the position of the end effector when the robot approaches the same position several times.
Absolute Precision is the precision the robot approaches a xyz coordinate with. This is e.g. important in camera-based applications. The absolute precision is always worse then the repeatability.
Velocity and Cycle Times
- The joint velocities are between 45 and 60°/s
- Cartesian velocites are possible up to 300 mm/s, depending on the situation
- Cycle times below 5s are for many cases not quite realistic
Perfectly suited applications are: Pick-and-place, assembly, quality assurance, ...
If the robot is to be used for camera based gripping of small objects, in case of low cycle times, precise path following in milling or writing, etc., we should discuss the application first and potentially verify experimentally that the application is suitable.
We do have several robots in our workshop. It is possible for us to set up verification experiments. This way we can find out, whether the robolink arm is well suited for the application. Please get in contact!
General Pros and Cons
- Low investment cost
- Easy to use graphical programming environment
- Easy maintenance due to straight forward mechanical design and separation of mechanics and electronics
- High speed applications are not supported, joint speed is limited to 45 to 60 °/s
- The application has to conform with the available number of joints and payload / reach limits
