Robotics and Physical AI Engineer Intern at NCS3

As a Robotics and Physical AI Engineer Intern, you will be involved in cutting-edge deep tech development of robotics and physical AI systems that mimic human movement and behavior. You'll contribute to building advanced humanoid robotic systems through hands-on work across the full project lifecycle—from planning and simulation to deployment and maintenance. This is an opportunity to work on real-world applications that bridge high-level AI reasoning with physical motor control, bringing intelligent robots to life. Intern's Job Scope You will work across various subsystems of robotics and physical AI, with responsibilities including: Simulation & Environment Development • Design 3D training environments (homes, factories, stairs) using NVIDIA Isaac Sim, Gazebo, or Unity • Build and validate robot behaviors in high-fidelity simulation environments before physical deployment • Create simulation-ready meshes using CAD software (SolidWorks, Autodesk Fusion 360, Blender) • Implement 3D sensor models (LiDAR, depth cameras, IMUs) with realistic noise profiles • Generate synthetic data and apply domain randomization techniquesControl & Locomotion • Develop algorithms for stable bipedal walking, balancing, and recovery from disturbances • Apply reinforcement learning (RL) and whole-body control strategies • Refine forward and inverse kinematics for human-like movement with high degrees of freedom • Author and maintain robot description files (URDF & SDFormat) defining kinematics, joint limits, and inertial propertiesAI Integration & Safety • Bridge high-level AI (vision-language models) with physical motor control • Implement robust safety and fallback systems to prevent physical damage or injury when AI models behave unpredictably • Develop platform orchestration layers managing communication between AI reasoning and motor control with low latencyHardware-Software Integration • Collaborate with mechanical and electrical teams to integrate sensors and actuators using ROS 2 • Maintain digital twin synchronization between 3D simulation models and physical hardware • Design and maintain APIs for subsystem integration • Work with projective geometry, coordinate transforms (TF2 in ROS), and mesh format conversions (STL, OBJ, USD, Collada)Software Engineering & Testing • Emphasize code maintainability, version control (Git), and CI/CD pipelines • Design monitoring tools and fail-safe layers • Work with containerization (Docker) for consistent software deployment • Develop test frameworks for system validation
