During the 42 months of activity, the consortium has achieved the following progresses: 1) a measurement system to assess the capability of liquids to respond to electrical stimulation, with a broad band resolution. A dedicated integrated circuit for extracting holonomic features from the colloids 2) We have discovered a protocol for implementation of learning in several liquid systems via a programmable propagation of conductive pathways. Logic gates in colloids were mined and the demonstration of a rudimentary arithmetic logic unit was performed. Extremely promising results on reservoir computing in colloid systems were achieved, including the demonstration of in memory computing, of liquid analogue memory, of liquid state artificial recurrent neural network, and liquid state artificial synapses. 3) Alternative energy supply in the soft cybernetic system was explored with the idea of inducing the conversion of light into heat directly in the liquid phase, avoiding solid interfaces, and to exploit with a mixed composition the resulting thermal gradient into electrical power. By adapting thermogalvanic materials to our scopes, an energy generation capability as high as 1 mW/K has been demonstrated, over the typical surface areas of the final prototype. 4) A great evolution in the synthesis of self-healing polymers for the fabrication of containment skins, and the first prototype of COgITOR truncated icosahedron were achieved. A technological roadmap to shape the skins, to host the pressure sensor, the energy harvesting gels, create the metal electrodes on the inner surface of the sphere, and encase the holonomic chip for the final demonstrator, was settled. A specific composition of the soft skin, allowing room temperature self-healing, has generated a record of invention case and a potential new patent. 5) The discovery of room temperature, non-local effects of probable quantum origin in colloids, which represents by itself a game changing discovery, is under referral and opens a scenario of profound innovation not only in soft robotics, but also in biology, considering that many biological fluids are colloids.
