Development repository for the 2026 Triton Robotics Float.
Overview
The Triton Float is being developed for the 2026 MATE ROV Pioneer competition (Newfoundland). This design iteration is approximately 33% smaller than last year's model, while targeting more than 2× performance improvements in speed and significantly increased precision through layered redundancy and sensor feedback systems. It also includes a dedicated LoRa radio as opposed to last year's 4cm wire antenna, which will increase the reliability and robustness of the system.
Features
Dimensions: 200mm x 4 in diameter. Buoyancy system: PWM pump ranging from 220mL/min to -220mL/min.
Accuracy Strategy:
- Internal pressure sensor for ballast state verification
- Pump movement feedback sensor for closed-loop control
- Pre-calibrated pump flow rate modeling for predictive adjustment
- Additional onboard MCU sensors for reproducible control accuracy

Notes:
Structural Considerations:
Cylindrical housing designed to fit within a 4 in diameter constraint
Internal layout arranged to allow operation in the case of flooding (up to ~50-75% of internal volume) while maintaining core electronic functionality.
PCB mounted using tight-tolerance standoffs to prevent movement under vibration and ease serviceability
Layer system used to keep the float intact when the top flange and shell is removed.
Integration Notes:
Limited internal volume required careful routing of wiring and tubing
Added solderable vias for power, in order to have a secure connection to the battery.
Accessory PCB used to isolate power regulation from main control logic
R3 revision addresses footprint issues and uses a different simpler power system for a working prototype.
Current Status
- Version / Revision: R2
- In progress: R3, with fixed tracing and the internal pressure sensor.
- Completed: R2.
- Next steps: Testing R3 when it comes in.

Questions
How big is the FlightController Chipstyle PCB?
It measures 97 × 95.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FlightController Chipstyle use?
15 parts, built around the MS583702BA01-50 and RFM95W. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the FlightController Chipstyle KiCad files?
From the Simonhajd/Triton-Float repository on GitHub, at the commit this page was made from: the board is PCB/FlightController/FlightController-Chipstyle.kicad_pcb and its schematic ACC PCBs/HallPCB/HallPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FlightController Chipstyle design in my own project?
Its repository states no licence, so its author keeps all rights: ask Simonhajd before reusing the design.
