This year, we were faced with a new set of challenges. Current Events made us entirely rethink the space in which the robot operates. The robot is primarily designed to efficiently move trash from the gyres to the engineer, where sorted micro-plastics can be placed. The segmented arm can detach a ramp and net from both sides, allowing for flexibility for all challenges. All of our engineering is made possible by detailed designs, precision cut by a CNC to minimize weight and function efficiently.
The robot is designed to perform three tasks: rescuing the manikin, removing hazardous chemicals from the site, and putting out the fire. To dispose of the chemical cans, we implemented a lift that captures the cans using three flexible half-pipes. The whole implement is moved vertically by a threaded rod to lift the cans over the wall of the bin. To rescue the manikin, we attached small wires on the underside of the half pipes on the lift which catch the ropes that make up the manikin. Finally, we fling the water by using a wheel with piano wires protruding from a central rotor. The balls are contained in a half-disc so they have time to accelerate until they leave the disc and are released.
