Following an initial group effort, an actuated system was defined to be embeded in a rain harvesting system. As water collection is dependent upon the quality of runoff surface, the system would incorporate a mechanism to only open in the presence of rain. When closed, the structure would insulate catchment surface, this improving collected water quality.
The output subsystem project is actuated using a servomotor coupled to a mechanical transducer—rotational movement is translated into a back and forth linear displacement. An Arduino UNO Microcontroller is used in tandem with Firefly Grasshopper to actuate the system. When combined with input subsystem, the whole system is aware of rain events and deploys in response to them.
