Direct drive or Indirect? That’s the question.

The lecture will be given by Niels Koenraad, Nobleo Technology

Typical struggles in actuator selection are to balance upsides, such as high force, with the downsides of additional mass, volume and availability. Adding a transmission has its own downsides, such as friction, backlash and hysteresis. But what if a gear ratio can be created with the aid of flexure mechanics, eliminating all these downsides? How does one deal with the parasitic movements, the own guiding stiffness, dynamics and motor choice in a static use case? In this presentation, a pragmatic implementation is presented of an (in)direct-drive actuator that is self-guided and compliant in multiple passive directions to be used in a steady-state multi-axis kinematically coupled system.

We will start at 12:02pm on September 6.
