In this paper, I explore how bio-hybrid forms can be created and combined when starting out from organic forms. The thesis I advance here is epistemological: the combinatorial practice of bionics, biomimetics, biorobotics, and all design strategies inspired by nature is based not on biomimetic inspiration (i.e., on a kind of imitation of nature) but on a practice of translation. To develop this thesis, I focus on the practices of contemporary biorobotics. I examine the practice of translating natural forms into technical artifacts, as developed by Raoul Heinrich Francé during the early 20th century. I then analyze the making of robots capable of replicating complex systems of locomotion. Finally, I investigate the interaction between robots and living organisms (fish). In the concluding part of the paper, I reflect on the philosophical payoff and broader conditions of possibility for this translational practice. I discuss when and to what extent a translation of biological forms into biotechnical ones is acceptable, and also highlight the conception of form that underlies this practice. I additionally seek to draw attention to the need to philosophically investigate what happens between different domains of knowledge - especially between science and technology. Thus, this article invites philosophers to develop a philosophy in the interstices of knowledge production.
