For RoboSub 2025, ARVP is deploying Kenai, a new AUV designed for maximum reliability and task consistency, alongside our vision-based support robot, Koda. Kenai features simplified mechanical subsystems, standardized electrical architecture, and improved control stability to reduce downtime and increase success rates on previously attempted tasks.

Here’s how we plan to tackle the course:

1. Gate: Kenai will pass through the shark side of the gate, then signal Koda to follow. Koda will perform two barrel rolls for maximum style points before continuing its run.


2. Slalom: Koda will use its updated vision servoing system to navigate between red and white pipes, aligning precisely and repeating this for each pipe set.


3. Dropper: Kenai will proceed directly to the bins, dropping both markers into the shark side. This subsystem remains largely unchanged due to its proven reliability.


4. Pinger: Kenai will use acoustic cues to determine whether to approach the table or torpedo task first. If the table is prioritized, it will backtrack to torpedoes afterward.


5. Torpedo: From 0.3 m away, Kenai will fire at the shark and sawfish holes. The redesigned launcher is faster and more accurate, improving overall task reliability.


6. Table: Kenai will align and surface inside the octagon, then use its new claw—featuring current sensing for grip verification—to pick up bottles and drop them into bins. Vision checks ensure successful deposits.


7. Return Home: After completing the slalom, Koda will navigate home using visual alignment with the back of the gate.
