robolink® - Multiple-axis joint for robots
user reports

Development partner EvoLogics GmbH is a specialist for bionic inventions (the Fin Ray Effect®, among others). The ideas for the actuation of the joints through "sinews" and the entailing decoupling of the moving masses of the drive technology (bionic model: the foot of a crane. Muscles in the bird's body move the toes of the animal via sinews, the leg is extremely long, thin and therefore light).

 
Evologics plant: the torso.

Each arm has 7 degrees of freedom, 4 of which in the 2 robolink® joints, respectively. Each arm is driven by 7 DC motors; they are stationary in the "breast area".
Due to the decoupling of the drives from the moving arms, each arm only weighs a little over 1 kg. Load capacity per arm is also 1 kg with very high dynamics.
Result: a load to dead weight ratio of 1:1 becomes possible!

New: Angular sensor system
Due to the integrated angular sensors, an arm can also be used directly as "teach-in" arm. Read-out angle information can be saved and called up or even directly transformed into movements (see part 2 of the film). Currently the sensor technology is advanced for series production.
