Dye Penetrant Arm Attachments for BIKE Robot

     For the work period of February 4 - 17th, the team has made design updates to the arm to reduce the amount of moment it’s experiencing by elongating the height while decreasing the width. The team made changes to the hinges based on feedback from the sponsors after the initial fabrication experienced errors in printing. The updated hinge design was applied to the developer box, both electronics boxes, and horizontal attachment component box. After fitting the components to the box, the team decided to increase the height of the components box (Figure 1) to better hold the peristaltic pump without causing the tubing to bend. Furthermore, the team started the validation process for peristaltic pump exit pressure and pressure near nozzle.      For the work period of February 17- March 9, the team plans on receiving the new fabricated pieces and test fitting all components, completing all water pressure validation, strain gauge testing for arm attachments,...

     For the work period of December 11-February 3, the team has met with stakeholders to make final adjustments to the design before sending the CADs’ for fabrication. The team redid the stress analysis to simulate a better representation of the load applied to the arm attachment. Currently the team is fabricating fittings for the nozzle and tube connection to allow a seamless attachment for fluid flow. The team is also purchasing a pressure gauge and T-fittings for further project validation.       For the work period of February 4 - February 17, the team plans to assemble all the fabricated components, confirm that the parts work together within the design, and proceed with validating the goals set at the beginning of semester 1. Major milestones the team hopes to achieve include assembly of all the components, validation of the nozzle pressure, distance of the spray, fluid temperatures, and battery life of electronics to cross reference with rea...
