Continuum Robot Design and Prototyping

At CRL, we create innovative continuum robot designs with novel features such as drastically increased motion capabilities through extensibility, adjustable stiffness through scale sheaths, and higher accuracy through parallel structures.

In terms of designing continuum robots a wide spectrum of compliance and elasticity can be achieved by variation of materials, structure, actuation, etc. We aim at developing particularly small continuum robots which are able to manoeuvre and manipulate in constrained and tortuous environments.

In addition to the physical design of continuum robots, research @CRL is also concerned with computational design. For instance, we are developing evolutionary algorithms and machine learning techniques to explore the infinite parameter space of tubular continuum robots and derive design guidelines.
