Electromechanical kinetic sculpture. Designed, fabricated, and integrated a motor-driven mechanism system that produces organic movement with PLA external shell and internal mechanisms. A silicone membrane inflates to resemble breathing through dual air pumps. Handled the full electrical and mechanical build from CAD through to finished piece.
Technical:
Crankshaft linkage for abdomen movement. Articulated tail with pulley mechanism. MOSFET-driven air pumps for silicone air sack inflation. Arduino motor control with A4988 motor controllers , coded with C++ with randomised organic movement loop. Torque motor selection and tuning. Nema 17 stepper tuning for sound design. Stainless steel laser cutting and TIG welding. 240V to 12V step-down power supply with earthing, PAT testing, and voltage regulation. Thermal management with fans and heatsinks. 2-pack epoxy paint and filler finish. Full electrical wiring and integration.
