Underwater Remote Operated Vehicle (U.R.O.V.)
During my spring 2017 semester at Rowan University, a team of 4 electrical engineering students and I created an underwater remotely operated vehicle (U.R.O.V.) to perform a series of tasks while submerged as part of my Sophomore Engineering II course. The U.R.O.V. was designed in SolidWorks and its speed, maneuverability, and stability were optimized using SolidWorks and SolidWorks Flow Simulation. The objectives of the project were as follows:
- Travel along a 10m straightaway in the fastest time possible.
- Successfully navigate a PVC obstacle course.
- Clear a field of debris by collecting and bringing it to the top of the pool.
- Cap an “oil well” by successfully placing a PVC cap on top of a pipe on the bottom of the pool.
- Collect a water sample near the area where the “oil well” is located.
Results & Discussion: During our final test, the U.R.O.V. performed exceptionally well and, even though it was able to collect only one piece of debris from the bottom of the pool, it performed every other task without fail. Since we allocated a considerable amount of time towards maximizing the stability of our UROV using a 2k factorial design process, the device ended up being one of the most maneuverable UROVs developed during the semester, despite being fairly large in size.
To collect the water sample near the area where the “oil well” was located, our team devised a particularly elegant solution. When the PVC cap was placed onto the “oil well” and the UROV would move in reverse, the PVC cap would slide off of our PVC cap holder and cause a small cotter pin holding back a spring-actuated syringe to be yanked out of a small hole. The spring inside the syringe would then actuate, causing the syringe to automatically collect a water sample moments after the “oil well” was capped.
My Contribution: Considering I was the only mechanical engineering major on our team, I did a vast majority of the work related to 3D modeling, performing fluid simulations, and optimizing the U.R.O.V.’s stability . As a result, I learned a ton about SolidWorks modeling, assembly configurations, and flow simulations.
