Dye Penetrant Arm Attachments for BIKE Robot

       For the work period of November 11th through 25th, the team has redone several engineering analyses to accommodate the sponsor company’s additional project scopes and part changes. The sponsor company has stated that they would prefer if the team is able to work with an additional robot to spray the developer during the dye penetrant test. Thus, the team has utilized the same design used in the first robot (Figure 1) and updated it to use the developer spray can (Figure 2). The analysis completed includes static calculations using free body diagrams, flow rate calculations on the nozzle, power calculations between the components, and estimated run time calculations. Several simulations were done in SolidWorks in areas of stress, strain, and flow rate to emulate what the nozzle and arm attachment would experience when using the product. Currently, the team is finalizing the accuracy of the CAD model to calculate the factor of safety with the arm attachments, as well as analyzing

During the weeks of October 28 - 11, we constructed and assembled the CAD components of the arm attachments, selected materials, and completed our initial engineering calculations. Additionally, we scheduled meetings with the clients in order to present our design ideas, gather feedback, and get approval for items for purchase. After last week’s meeting, the client informed us that they would like to add another project scope. The client wants to utilize a second BIKE platform to spray a developer. This incorporates a third action into the team's design. In order to complete the new project scope, we have divided the work into 3 tasks: CAD design for the developer can, building the enclosure for the first BIKE robot, and completing any additional engineering analysis for the developer can assembly.  The team expects to finish the engineering analysis for the project during the timeframe of November 11 through November 25. Such calculations include determining the flow rate of the
