Unmanned Autonomy
Dynamic Dimension Technologies, LLC
Unmanned Autonomy showcases VxSIM, Dynamic Dimension Technologies’ next-generation digital twin environment for developing and validating advanced autonomous behaviors in maritime systems. Designed to accelerate AUKUS and Indo-Pacific innovation, VxSIM enables defense and industry teams to simulate, test, and refine autonomy before field deployment—reducing risk, cost, and time to readiness.
The system integrates real-time physics-based boat dynamics, navigation stacks, and mission logic across distributed computers to replicate complex maritime conditions and communications constraints. As shown, VxSIM synchronizes remote vessel dynamics with local autonomy planning, allowing collaborative testing of unmanned surface and subsurface vehicles (USVs/UUVs) under dynamic ocean environments.
By supporting live-virtual-constructive experimentation, VxSIM provides a unified platform for human-machine teaming, evidential reasoning, and multi-vehicle coordination—enabling coalition partners to validate AI-driven control algorithms, adaptive routing, and mission resilience. Its open-architecture design supports integration with ROS/ROS2, autonomy toolchains, and national simulation frameworks.
Through VxSIM, partners across the AUKUS alliance and Indo-Pacific region gain a sovereign capability to safely advance next-generation autonomy, enhance maritime interoperability, and strengthen defense collaboration through digital twin–driven experimentation and validation.

Next Generation Naval Design Tools
DDT was awarded an SBIR contract from the US Office of Naval Research to extend our VxSIM simulation technology, to fully embrace computational capabilities in the design process of maritime vehicles. The process leverages the exploration of advanced concepts, the use of big and sparse data (such as operational and experimental data, high- and low-fidelity simulations, and reduced order models), machine learning and artificial intelligence methods, and builds upon rigorous mathematical foundations of multi-disciplinary design optimization. The workflow also includes virtual performance trials to verify the design requirements and can be implemented using either single- or multi-point design approaches. The effort focuses on the transitions of these tools and methods to Engineers, by designing and developing user interfaces to facilitate rapid ship design, optimizations and acquisition (e.g., cost estimation, manufacturing and outfitting).

About
Innovation at Dynamic Dimension Technologies isn't just about technology; it's about creating a safer, sustainable future for all.
Dynamic Dimension Technologies (DDT) builds VxSIM—an applied digital-twin and autonomy testbed that links design, training, and production. We help naval and manufacturing teams rehearse sea states, comms, procedures, and shop-floor automation before deployment. Focus: Next-Gen Naval Design Tools (trade studies, baseline safety/survivability), design-for-manufacturing, robotic cells/arms with controller/PLC bridges, and multi-sensor safety (cameras/LiDAR/radar/light curtains). We deliver scoped pilots with hard metrics that de-risk integration early and translate cleanly to partner delivery.
What we do
• VxSIM platform: physics-grounded sim + controller/PLC bridges + live sensors for naval & manufacturing programs.
• Next-Gen Naval Design Tools: early trade studies, baseline survivability/safety checks, mission-profile rehearsal (radios/controls-in-loop).
• Design for Manufacturing (DfM): link CAD, routing, and cell layout to existing control stacks (PLC-driven cells, vendor motion controllers, EtherCAT/CAN/DDS/Modbus/OPC UA, OEM SDKs).
• Robotic arms & cells: reach/clearance, path planning, cycle-time; validate interlocks in sim first.
• Multi-sensor shop-floor safety: cameras, LiDAR, radar, light curtains into Safe/Slow/Stop logic; test edge cases before install.
• Training & workforce: hands-on twin environments aligned to real tools.

For naval and uncrewed systems, our VxSIM product enables trade studies, baseline survivability/safety checks, and mission-profile rehearsal—with radios and controls in the loop to surface integration issues early. For manufacturers and shipyards, VxSIM supports Design for Manufacturing (DfM) and production readiness: linking CAD and process routing to existing control stacks—PLC-driven cells, vendor motion controllers, EtherCAT/CAN/DDS/Modbus/OPC UA, and OEM SDKs—plus robotic arms (reach/clearance, path planning, cycle-time). Our safety workflows fuse cameras, LiDAR, radar, and light curtains with multi-zone logic (Safe / Slow / Stop) to validate layouts and interlocks before the line goes live.
Outcome: fewer surprises, faster training cycles, and clearer go/no-go decisions. We favor scoped pilots that answer concrete questions—“Is this ship/hull design stable?”, “Can this arm finish the weld with current fixtures?”, “Do our safety zones catch edge cases?”—then scale.
Current projects & proof points
• Naval: mission-profile rehearsal for USV/ACV concepts; exercise radios/controls in loop to surface integration issues early.
• NG-NDT: toolkit for rapid design trades and baseline safety/survivability checks tied to field use.
• Manufacturing/Shipyards: DfM and robotic cells with controller/PLC bridges; validate multi-sensor safety zones before the line goes live.
• Cyber/Human factors: role-based operator surrogates to test procedures/training with realistic timing and comms discipline.
