3D Test Systems

In Short

Complex 3D motion profiles are simulated using a 6-axis robot. Individual human motion data and forces, recorded in our motion lab, are used for programming the robotic system. As a result, the robot can realistically emulate human motion patterns in a force- and position-controlled manner.

In Detail

Evaluating and measuring mechanical stress on products worn on the human body such as orthoses, prostheses, shoes or other technical systems is a highly complex issue. Our daily activities begin when we get up and continue throughout the day as we perform various movements, such as walking upstairs, carrying additional loads, until we finally sit down to rest. However, current test methods only cover some of these daily activities, primarily walking in the sagittal plane. Realistic testing requires an in-depth understanding of user behavior as well as of the test equipment implemented.

Advantages

The innovative, robotic testing method allows real, human motion patterns to be simulated. New information about the strength and wearing behavior of technical products based on realistic load scenarios can be generated. These experiences help better medical products to be developed that meet the requirements of our demanding daily life.
