2 Who We Are Started in January 2015 Principals Jeffrey Smith CEO 20+ years Defense, 10+ years in UUVs John Vestri COO/CFO 8 years in ROVs Dr. Dani Goldberg SW Principal 20+ yrs in Autonomy, 10+ yrs in UUVs 20 Current Employees multiple openings Currently working from Greentown Labs, Somerville, MA Permanent Facility in Plymouth September 2017

3 muuv Overview MOOS-DAWG July 30, 2015 Riptide s First Public Release

4 Vehicle Background May 2015 Riptide kicked off its initial prototype design which concluded with its first in-water trials September 2015 at the ONR Patuxent River Demo. Rapid development timeline was achieved by a small integrated team through extensive use of COTS and rapid prototyping techniques. Since the demonstration we reassessed the vehicle design and made modifications required to support endusers and operators in preparation for initial production deliveries, including utilization of MOOS.

5 muuv Overview Initial Prototype Vehicle (2015) Current Generation 4 7/8 inches in diameter 29 to 60 in length ~20 lbs 300 m rated

6 Vehicle Flexibility Standard Vehicle Mini w/ 900kHz Sonar Standard Vehicle with flooded payload bay Standard Vehicle with additional dry payload bay Standard Vehicle with additional 900 khz Sonar Custom Vehicle w/ ACOMMs & 900 khz Sonar

7 Very Low Logistics

8 Persistence Riptide has driven hydrodynamic and power efficiency way up Riptide has partnered exclusively with L3-Open Water Power to field a breakthrough, highly energy dense power solution At 5 kwh, the muuv has a range of >1500 nmi at 2.8 knots Prototype muuv 18W Hotel Production Mk1 muuv 9.5W Hotel Production Mk2 muuv 3.5W Hotel 2 2.2W Estimated 2 2W 2 1.6W

9 Qualified Deep 200m Rating has increased to 300m standard Alternate Material Options exist to depths of up to 6000m

10 Swarming Riptide is enabling swarming of UUVs by Providing capable, low-logistics vehicles at an affordable price Providing significant persistence

11 Basic Architecture Nose: Vehicle Sensors: Pressure, temp, altitude, IMU Main Computer Power Distribution OLED Display Tail: Propulsion: 350W external motor (3000m rated) Vehicle Control Actuators (fins) Communications (WiFi standard) Emergency Systems: Dropweight / LED strobe GPS Midbody: Power Payload: Dry or flooded volumes

12 MOOS Architecture MOOS MOOS Common Components pantler MOOSDB plogger pmarinepid pnav iriptidemicrouuv Interface to Riptide i2c bus Most sensors and actuators Other Device Interfaces Non-I2C devices E.g., modems Vehicle Hardware UNCLASSIFIED//REL TO USA, NATO

13 Open Source and Architecture Some customers do not want to modify the vehicles (at least not immediately) Other customers view the vehicles as a starting point for their own development, research, etc. We provide a good deal of information to support these customers Source code is available to customers MOOS, of course, but also Riptide-developed source Architecture diagrams provided to customers Signal and power cabling diagrams Provide computer images, development environment, and updates of source code, documentation and executables UNCLASSIFIED//REL TO USA, NATO

14 Customer Development Customers have made many modifications to the vehicles for their efforts, including: Adding multiple new actuators with HW/SW interfaces Adding payload computers running their own algorithms with interfaces to MOOS and hardware Modifying core vehicle software on the vehicles Developing their own battery packs UNCLASSIFIED//REL TO USA, NATO

15 Riptide Development Leveraging open source software such as MOOS has also aided Riptide s development efforts Utilized Goby/MOOS for communications Developed MOOS interfaces for IMU s, the OLED display on the vehicle, camera, etc. Given sets of standard MOOS messages, we have swapped out different sensors with little ripple effect (demonstrating good modularity) UNCLASSIFIED//REL TO USA, NATO

16 Mission Planner Based on OpenCPN Add the notion of depth Translation to MOOS mission format

17 muuv Scalability Riptide is building a Family of Man-Portable UUVs Standard muuv ~22 lbs / 300m Diameter 4 7/8 (A) Standard 1MPUUV ~62 lbs / 300m Diameter 7.5 Standard 2MPUUV ~140 lbs / 600m Diameter 9 3/8 Riptide Proprietary Information
