The team had a major milestone this week, wrapping up our SLDR on December 2nd. The review presented an opportunity to share the current status of our system, walk through design decisions, and receive detailed feedback to help guide the next phase of development. Attendees from Johnson and Johnson and the University of Florida discussed various aspects: physical architecture, bill of materials, verification strategy, preliminary manufacturing considerations, early prototype results, and overall project planning. Feedback was positive and shed light on multiple technical priorities in the coming months.
Much of the review was confirmation of the direction of our mechanical and vision subsystems. The panel agreed that it was reasonable to continue the development of a cooking fixture and its camera mount because of its importance in ensuring uniformity in the handling and alignment of components for making a catheter. Strong support was given for the creation of a formal verification box concept, which will facilitate orientation checks and camera alignment by providing a controlled environment in which to take images and perform calibration. This will be important both during algorithm development and in system integration.
The team also confirmed the path forward for completing the one-to-one scale prototype using motors, timing belts, and pulleys. Parts have already been ordered for this build using the existing budget, and the review reinforced the importance of demonstrating the full mechanical assembly in Spring. This prototype will form the basis for validating subsystem interactions and preparing for more advanced automation work.
On the software and sensing side, the reviewers supported our current computer vision approach to detect the copper wire and to identify the proximal and distal tip of the catheter. Iteration of these models will continue to be critical for reliable part verification across a large variation in catheters. Testing will be expanded to include correct and incorrect samples so the vision pipeline can be evaluated against real sources of variation.
Based on the results of the SLDR, we proposed a very clear path forward for each of the subsystems. On the mechanical side, the next few weeks will involve updating the CAD for the cooking fixture and camera mount, printing revised prototypes, and checking functionality. In parallel, concept drafting and a test plan for the verification box will start, along with initial bill of materials planning. The remaining parts for the one-to-one prototype will be assembled as they come in, and the team will start alignment and bring-up testing. Vision work will continue to include model tuning and expanded sample evaluation, while the BOM will be updated to reflect confirmed components and lead times.
All said and done, the SLDR was a productive and energizing moment for the team. The review validated our direction and provided clarity of expectations for the next phase, while strengthening our alignment across mechanical, software, and verification efforts. The insights gathered will be incorporated into the final SLDR report and will help in guiding our work into Spring.
