The mechanism makes use of a sliding-crank linkage to maximise the tolerance between the boat and its target, while working within the tight constraints provided by the boat hatches to allow the mechanisms to be fully retracted when not in use (opening up the potential for the arms of another boat to latch into the mechanism). Once deployed, spring-loaded ‘power-off’ brakes secure the final position without consuming further power. <img width="4032" height="3024" width_o="4032" height_o="3024" data-src="https://freight.cargo.site/t/original/i/254aa9805b2606857f73902949c92f1a47fffd655d4b8c29cafd30fb9744eb1e/IMG_8560.JPG" data-mid="118223214" border="0" src="https://freight.cargo.site/w/1000/i/254aa9805b2606857f73902949c92f1a47fffd655d4b8c29cafd30fb9744eb1e/IMG_8560.JPG" /> <img width="2654" height="1224" width_o="2654" height_o="1224" data-src="https://freight.cargo.site/t/original/i/f599a8446356c1cadc4768db58776a85d1acb31750c08423d93e91dc10b78d86/CAD-both-latching-boxes.png" data-mid="119082829" border="0" src="https://freight.cargo.site/w/1000/i/f599a8446356c1cadc4768db58776a85d1acb31750c08423d93e91dc10b78d86/CAD-both-latching-boxes.png" /> <img width="2500" height="441" width_o="2500" height_o="441" data-src="https://freight.cargo.site/t/original/i/c51f187b854b6e3297914ae2bd605a9cd2ac679764916df91094f0cc6b6bd110/latching-sequence-roboat-_cropped_transparent.png" data-mid="164962703" border="0" src="https://freight.cargo.site/w/1000/i/c51f187b854b6e3297914ae2bd605a9cd2ac679764916df91094f0cc6b6bd110/latching-sequence-roboat-_cropped_transparent.png" /> <img width="3024" height="4032" width_o="3024" height_o="4032" data-src="https://freight.cargo.site/t/original/i/521e80c5f1739fc8e21de12cffd65a83a496f8b342e9c6e30b2d6d81c74531ae/IMG_9512-2.JPG" data-mid="129113309" border="0" src="https://freight.cargo.site/w/1000/i/521e80c5f1739fc8e21de12cffd65a83a496f8b342e9c6e30b2d6d81c74531ae/IMG_9512-2.JPG" /> -- Two latching mechanisms installed in the central bays of the full-scale Roboats at the Marineterrein in Amsterdam.

With weight as a primary constraint, permanent magnets showed superior strength compared to electromagnets in allowing the boats to latch at a reasonable distance (~10 cm). A light-weight origami-inspired mechanism was developed - with a single servo in the centre actuating magnets on all four sides of the boat. The design was broken down into small easily printable parts and strips of rubber for the flexible components. <img width="3024" height="4032" width_o="3024" height_o="4032" data-src="https://freight.cargo.site/t/original/i/4b75912a5e9ddf07012246bb08fa1cf6ed4c022d16604b28417598af90cebf66/IMG_7312.jpeg" data-mid="120497077" border="0" src="https://freight.cargo.site/w/1000/i/4b75912a5e9ddf07012246bb08fa1cf6ed4c022d16604b28417598af90cebf66/IMG_7312.jpeg" /> <img width="1510" height="1198" width_o="1510" height_o="1198" data-src="https://freight.cargo.site/t/original/i/af944d3cbf61630384118040af5b96fd36a3d528bf2778b19fd293a033237d7f/CAD-mini-boat-white.png" data-mid="122519594" border="0" src="https://freight.cargo.site/w/1000/i/af944d3cbf61630384118040af5b96fd36a3d528bf2778b19fd293a033237d7f/CAD-mini-boat-white.png" /> <img width="4032" height="3024" width_o="4032" height_o="3024" data-src="https://freight.cargo.site/t/original/i/ed10a112a5b1fe24b1753e6f4feaa1f9d7a6e2e6fdee138b096814a0a26e398c/bottom-view-_-thrusters-miniboat.jpg" data-mid="169560802" border="0" src="https://freight.cargo.site/w/1000/i/ed10a112a5b1fe24b1753e6f4feaa1f9d7a6e2e6fdee138b096814a0a26e398c/bottom-view-_-thrusters-miniboat.jpg" /> <img width="2284" height="1818" width_o="2284" height_o="1818" data-src="https://freight.cargo.site/t/original/i/dd4ce1ba67a82c7d3bcb1110e83bdd533f77c6c7107bb8b115754f8456ac759a/iso_ish_view_cropped_2.jpg" data-mid="169004846" border="0" src="https://freight.cargo.site/w/1000/i/dd4ce1ba67a82c7d3bcb1110e83bdd533f77c6c7107bb8b115754f8456ac759a/iso_ish_view_cropped_2.jpg" /> <img width="3314" height="2454" width_o="3314" height_o="2454" data-src="https://freight.cargo.site/t/original/i/4d1e76fbca04fec412e33c0691801604265357c0d20ba173fc4cabd31433fa4b/miniboats_square_formation_2.jpg" data-mid="159652680" border="0" src="https://freight.cargo.site/w/1000/i/4d1e76fbca04fec412e33c0691801604265357c0d20ba173fc4cabd31433fa4b/miniboats_square_formation_2.jpg" /> Taking ispiration from earlier experiments in compliant auxetic structures, the mechanism is pieced together from simple 3D printed pieces and rubber strips for the hinges.

Custom-made electromagnets under each key create dynamic areas of repulsion and attraction in response to the evolving harmonies of the music being played. A wearable finger attachment allows the player to get an immediate tactile sense of the musical dissonances and harmonies while they are playing; a musical force-field where the "right" notes attract, and the "wrong" notes repel. [1] Java app coded in Processing, visually highlighting the direction/pull of chord progressions to augment the physical forces being felt by the player.
