Abstract: A method for producing a flexible mechatronic system includes: a step of modeling the system by a mesh composed of a given combination of elementary blocks, each block being formed of a predefined assemblage of segments representing elementary beams, the mesh including at least one active block controllable by means of a control signal; a step of simulating the behavior of a terminal node of the model in open-loop response to a control signal; a step of characterizing the response by at least one static mechanical criterion and at least one numerical criterion representative of the decay of the resonance spikes of the response as a function of frequency. The above steps may be repeated. They are then followed by a step of selecting a design as a function of the criteria defined in the characterization step, the system being produced on the basis of the selected model.

Abstract: The invention relates to a longitudinally-steerable structure, comprising essentially longitudinal actuators made from shape memory alloy, Peltier effect elements with N and P doping and electrical control device. The above is characterized in that the actuators are arranged in pairs in an antagonistic manner, each actuator being connected at the ends thereof with a Peltier effect element with N doping and a Peltier effect element with P doping respectively. The invention further relates to an endoscope comprising at least one such structure.
