Abstract/Summary

This Senior Project Report document outlines the senior design project for Girl Scouts of California’s Central Coast (GSCCC) led by a team of four Mechanical Engineering students at California Polytechnic State University, San Luis Obispo. The project encompasses the researching, designing, prototyping, and testing of a LEGO robotic arm for the Girl Scouts to learn more about STEM (Science, Technology, Engineering, and Mathematics) and provide support to each Girl Scouts cookie sales in their stores. Their goal was to build a LEGO robotic arm that will interact with customers at the Girl Scout stores and promote the girl scouts' interest in STEM. Therefore, the Mechanical Engineering group was tasked with creating a robotic arm with an interactive feature. Initial sponsor meetings and requirements along with product, customer, and technical research helped the team establish the project specifications. The team constructed a robotic arm that recreates realistic arm movements to execute the Girl Scout honor hand sign through with the use of interactive activation features, as well as safety features. Upon gathering results from initial testing, changes were made to the code and design in order to meet our sponsors' expectations. The final tests were carried out to ensure all specifications were met. Final suggestions for improving the design and testing were made based on the final test results and are presented within this report.
