| Summary: | This paper presents a lightweight and fully customized fabrication of a 3D printed
microscale tilt-rotor tricopter for search and rescue missions in tight and uncertain environments
where size, agility, cost, and manufacturing time could be of essence. Particularly, we utilize
additive manufacturing for its advantages in low-cost customization of complex lightweight
systems, and rapid on-demand printing and fabrication of parts to meet urgent mission
requirements. Considering the mission requisites, the microscale tilt-rotor tricopter frame is
designed and optimized in a computer-aided design software to compactly incorporate the
electronics with minimal parts and weight. For the desired weight and durability, the parts are
printed with acrylonitrile butadiene styrene in a desktop 3D printer. These methods produce a lowcost and agile microscale tilt-rotor tricopter weighing 532g and sizing 168 (radius) × 98 (height)
mm that can be fully printed in less than 10 hours. Furthermore, we also demonstrate its tracking
control in an indoor motion capture system environment utilizing a nonlinear model predictive
control framework, which is implemented on an on-board Raspberry Pi 3 embedded processor. |
