lower cable friction due to Bowden cables with optimized friction couple.
2New design of articulated joint creates torque transfers in the region of approx. 15-20 Nm (or 5-10 Nm in continuous operation). There will also be three versions of articulated rod from the end of December 2009: aluminum (affordable), CFK (extremely light, but more expensive) and GFK as an intermediate solution.
3Integration of magnetic sensors to measure and transfer the positions of the articulated joint. Work is still being done on this. Space for the sensor system is provided and the technical design of the sensor mechanism should be completed and integrated sometime in 2010.
Transferable torque for the pivot movement: 10 Nm
drive force (cable tensile strength) for this: max. 400N
Transferable torque for the rotational movement: 5 Nm
drive force (cable tensile strength) for this: max. 400N
Weight 1 robolink® incl. cables: 380 g
Weight of aluminum rod: 270 g/m
Weight of carbon fiber rod: 150 g/m
Improving the design to increase the transferable torques between the articulated joint and rod
Reduce cable friction by making changes to the design and materials
Above all, integrate magnetic sensors to measure and transfer the positions of the articulated joint.
These, in our view, will provide the necessary improvements, but delay the plans for production.
We hope that, by the end of this year, we will be able to produce the first, finished, articulated robolinks by injection molding.
