Most robotics integrators work in software or hardware. ALT does both — simulating robot behavior in Isaac Sim, training policies with reinforcement learning, deploying on ROS2, and fabricating the physical hardware in-house. One team closes the entire loop from simulation to physical deployment.

Technology stack

The ALT robotics engineering stack.

ALT's robotics capability is built on the NVIDIA Isaac ecosystem and ROS2 — the open-standard platforms used by the world's leading robotics research groups and commercial deployments — augmented by ALT's own additive manufacturing and edge AI capabilities to close the sim-to-real gap.

Simulation to deployment

From Isaac Sim training
to real-world deployment.

The sim-to-real pipeline is where most robotics projects lose time and money. ALT's integrated workflow — from URDF design through Isaac Sim training, ROS2 integration, and physical hardware deployment — is designed to minimize the gap between simulated and real-world robot performance.

Why Isaac Sim closes the sim-to-real gap better than alternatives

Traditional robotics simulation (Gazebo, PyBullet) uses simplified physics that creates a large gap between simulated and real behavior — policies trained in these environments often fail on real hardware. Isaac Sim's GPU-accelerated physics, sub-millimeter contact dynamics, and photorealistic sensor simulation produce trained policies that transfer to physical robots with significantly less real-world fine-tuning. For Physical AI applications where real-world failures are costly, this isn't an academic distinction — it's the difference between a deployable system and one that spends weeks in hardware debugging.

Stage 01

Robot modeling & URDF/MJCF

ALT's mechanical design team creates the robot structure in SolidWorks, exports to URDF or MJCF format, and imports into Isaac Sim — with accurate mass, inertia, joint limits, and collision geometry. For Physical AI robots, ALT designs the physical hardware and the simulation model together.

Stage 02

Environment design & domain randomization

We build the simulated environment in Isaac Sim — including terrain variation, lighting randomization, object placement randomization, and sensor noise injection. Domain randomization is the key technique that makes trained policies robust to real-world variation that the simulation never perfectly captures.

Stage 03

RL policy training in Isaac Lab

Thousands of parallel robot instances train simultaneously on GPU — each experiencing different randomized conditions. ALT designs reward functions that encode the physical constraints and performance objectives of your application: stability, efficiency, task completion, safety margins.

Stage 04

ROS2 deployment & hardware integration

Trained policies are exported and deployed via ROS2 on the target edge hardware — NVIDIA Jetson, custom FPGA, or embedded MCU. Isaac ROS packages provide the bridge between trained models and hardware drivers. ALT validates in simulation before touching real hardware, and iterates rapidly when gaps appear.

Reinforcement learning

RL-trained robot policies
for real-world deployment.

Reinforcement learning produces robot behaviors that adapt to variation, handle novel situations, and improve over time — capabilities that scripted automation and classical control cannot match. ALT designs and trains RL policies for locomotion, manipulation, navigation, and perception tasks across multiple robot morphologies.

Locomotion policy training

Legged robots — quadrupeds, bipeds, hexapods — learn stable, energy-efficient gait patterns through RL in Isaac Lab. Policies trained across thousands of terrain variations (slopes, steps, uneven ground, gaps) produce robust locomotion that handles real-world terrain variation without explicit programming. Reward functions encode stability, efficiency, and target velocity tracking.

QuadrupedBipedGait optimizationTerrain adaptation

Dexterous manipulation

Robot hands and grippers learn object manipulation — pick-and-place, in-hand rotation, compliant grasping of deformable objects — through RL in Isaac Sim with physics-accurate contact dynamics. Force sensor feedback enables tactile-guided manipulation policies that adapt grip strength and approach angle to object properties in real time.

GraspingIn-hand manipulationForce feedbackDeformable objects

Autonomous navigation

Mobile robots learn obstacle avoidance, goal-directed navigation, and dynamic environment response through RL — going beyond Nav2's geometric planner to handle crowded, dynamic, and sensor-degraded environments. Policies trained across thousands of randomized environments in Isaac Sim deploy directly to real hardware via ROS2 Nav2 integration.

Multi-agent & swarm coordination

Multi-robot systems — drone swarms, warehouse robot fleets, collaborative manipulation — trained in Isaac Sim's multi-robot environment using multi-agent RL. Coordination policies emerge from individual reward signals without explicit programming of inter-robot protocols. Deployed via ROS2 multi-agent frameworks for real-world fleet operation.

Robot morphologies

Robot types ALT designs,
simulates, and builds.

ALT's robotics capability spans multiple robot morphologies — each requiring different control architectures, RL reward structures, and physical design approaches. The common thread is the Isaac Sim + ROS2 + edge AI stack that ALT applies across all of them.

Legged robots — quadrupeds & bipeds

Four-legged and two-legged robots that navigate terrain impossible for wheeled platforms. ALT trains locomotion policies in Isaac Lab across varied terrain — slopes, stairs, rubble, soft ground — producing gaits that adapt in real time to terrain variation through proprioceptive sensing.

Where ALT robotics systems are deployed.

ALT's robotics capability serves applications where fixed automation fails — where variability, unstructured environments, and real-world unpredictability require systems that perceive, reason, and adapt.

01
Industrial inspection & maintenance robotics
Autonomous inspection robots trained in Isaac Sim to detect structural anomalies, surface defects, and equipment failures in industrial environments — power plants, oil & gas infrastructure, manufacturing facilities. Visual SLAM and nvBlox for 3D environment mapping deployed via Isaac ROS on Jetson edge hardware. Anomaly detection policies trained on synthetic data generated in Isaac Sim using Omniverse Replicator — eliminating the need for large real-world defect datasets before deployment.
02
Adaptive manufacturing robots
Industrial robots that go beyond scripted automation — detecting part variation in incoming materials, adjusting assembly force mid-cycle, and flagging anomalies before they become defects. Force-sensor-guided RL policies trained in Isaac Sim with physical contact dynamics, deployed via ros2_control on real manipulators. Reduces scrap rates and line stoppages on production lines handling high-variation incoming parts.
03

Mobile robots for precision agriculture — crop monitoring, targeted treatment, and selective harvesting in unstructured outdoor environments. Legged platforms trained in Isaac Lab for traversal of varied terrain (furrows, mud, slopes) that wheeled AMRs cannot navigate. Computer vision pipelines for crop status assessment deployed via Isaac ROS on edge hardware in the field.
06
Search, rescue & disaster response
Legged and aerial robots trained for operation in post-disaster environments — rubble fields, collapsed structures, flooded terrain — where human entry is dangerous and wheeled platforms are inoperable. Locomotion policies trained in Isaac Lab across randomized rubble terrain, with sensor fusion architectures that maintain navigation capability when individual sensors degrade in smoke, dust, and low-light conditions.

Why ALT for robotics systems.

Most robotics vendors do software integration or hardware fabrication. ALT does the full stack — from Isaac Sim training and ROS2 deployment through in-house design and fabrication of the physical robot hardware. No integration overhead between the software team and the hardware vendor.

01

Isaac Sim + ROS2 + in-house hardware — one team

ALT trains policies in Isaac Lab, deploys them via ROS2, and fabricates the physical robot hardware in-house. The same engineers who write the RL reward function design the robot's mechanical structure and the edge hardware it runs on. No handoffs between simulation, software, and hardware teams.

02

Additive manufacturing closes the hardware gap

Novel robot geometries — topology-optimized structures, embedded sensor channels, gradient-stiffness components, biomimetic forms — require additive manufacturing. ALT prints robot components in PAHT-CF, PPA-CF, PEEK, and proprietary novel materials in-house, enabling robot hardware that a conventional machining shop cannot produce.

03

Domain randomization for robust sim-to-real transfer

ALT's Isaac Sim environments include systematic domain randomization — lighting, texture, mass, friction, sensor noise, environmental variation — so trained policies are robust to the conditions the simulation never perfectly models. This is what makes the gap between Isaac Sim performance and real-world performance manageable rather than catastrophic.

04

Edge-native deployment — no cloud dependency

Every robot ALT builds runs its perception, planning, and control on embedded edge hardware — Jetson Orin, custom FPGA, or embedded MCU — without cloud connectivity. For field robots, medical devices, and defense applications, cloud dependency isn't an option. ALT designs for edge-first from the start.

05

Novel materials for novel robot morphologies

ALT's synthetic tissue composites, biomimetic ceramic structures, and gradient-stiffness materials enable robot designs that conventional engineering materials can't support. Soft robots, biomimetic actuators, and prosthetic interfaces all require materials that behave like biology — which ALT develops in-house and prints directly into robot structures.

Common questions.

What robotics teams, research institutions, and product developers ask most often about ALT's robotics systems capability.

What is ROS2 and why does ALT use it for robotics?
ROS2 (Robot Operating System 2) is the open-standard middleware used by the majority of advanced robotics research and commercial deployments globally. It provides real-time DDS-based communication between robot components, hardware abstraction layers, and a mature ecosystem of packages for navigation (Nav2), manipulation (MoveIt2), and perception (Isaac ROS). ALT uses ROS2 because it is the standard — systems built on ROS2 integrate with the widest range of sensors, actuators, and third-party components, and benefit from continuous development by the global robotics research community.
What is NVIDIA Isaac Sim and how does it improve sim-to-real transfer?
Isaac Sim is NVIDIA's physics-accurate robotics simulator, built on Omniverse. Unlike traditional simulators (Gazebo, PyBullet) that use simplified physics engines, Isaac Sim provides GPU-accelerated rigid body dynamics, sub-millimeter contact simulation, photorealistic rendering, and realistic sensor models (LiDAR, camera, IMU, depth) that closely match real hardware behavior. The result is a significantly smaller gap between simulated policy performance and real-world robot behavior — trained policies transfer to physical hardware with less real-world debugging and fine-tuning than alternative simulators.
What is reinforcement learning for robotics and how does ALT apply it?
Reinforcement learning (RL) is a training approach where a robot learns behavior by maximizing a reward signal through trial-and-error interaction with its environment. In Isaac Lab, thousands of simulated robot instances train simultaneously on GPU — each accumulating experience across millions of timesteps that would take months to collect in the real world. ALT designs the reward functions that encode your robot's performance objectives, selects the appropriate RL algorithm (PPO for locomotion, SAC for manipulation), and trains policies that transfer to real hardware via domain randomization.
What is domain randomization and why does it matter for sim-to-real transfer?
Domain randomization is the technique of varying simulation parameters — mass, friction, lighting, sensor noise, object textures, joint stiffness — across training episodes, so the trained policy learns to be robust to variation rather than overfitting to a single simulated configuration. When deployed on real hardware, the real world's variations fall within the distribution the policy was trained on — rather than appearing as out-of-distribution inputs that cause the policy to fail. ALT implements systematic domain randomization in every Isaac Sim training environment as a core part of the sim-to-real pipeline.
Can ALT design and fabricate the physical robot hardware as well as the software?
Yes — this is ALT's core differentiator. We design robot structures in SolidWorks, simulate them in Isaac Sim, train control policies in Isaac Lab, deploy via ROS2, and fabricate the physical hardware in-house using additive manufacturing in carbon fiber composites, PEEK, and ALT's proprietary novel materials. Embedded electronics integration and edge AI deployment on Jetson or custom embedded hardware are included in the full-stack engagement. You do not need a separate mechanical engineering vendor or a contract manufacturer — ALT does it all.
What edge hardware does ALT deploy robotics AI on?
ALT primarily deploys on NVIDIA Jetson Orin (for perception-heavy applications requiring GPU inference), custom FPGA platforms (for deterministic real-time control loops), and embedded ARM MCUs (for lightweight control tasks). Model selection and quantization ensure that trained RL policies and perception models meet the latency requirements of real-time robot control on the target hardware — typically sub-5ms for control loops and sub-30ms for perception pipelines.
