| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 103 === The main objective of the study was to develop a piggy bank robot duck with interactive functionalities that spur savings by users. Specifically, the study required design and implementation of coin handling mechanism, a wing flapping and folding mechanism, a beak motion mechanism and a novel a skin growth mechanism.
Coin recognition was achieved by means of treebagger ensembles with bootstrap bagging algorithm on the hall sensor output. The wing flapping and folding mechanisms were achieved through 4 bar linkage mechanism following Grashof’s principles. A beak motion mechanism was also implemented through a linkage mechanism and was driven by a rack and pinion assembly connected to a servo motor. Lastly, the skin growth mechanism was achieved by coupling shape memory alloy (SMA) compression springs to suspended PLA body structure held in place by medium soft rubber.
In conclusion, all the laid objectives were implemented and the study proposes that in future, natural language processing capabilities be included in the piggy bank robot. In addition, the study proposes a mother piggy bank robot version be developed with coin egg laying capabilities.
