About the role
- Apollo relies on a complex, multi-modal perception suite to navigate and manipulate its environment.
- Your mission is to ensure these sensors act as a unified, mathematically perfect system.
- You will be the resident expert on optical physics, 3D geometry, and sensor precision.
Responsibilities
- As a Senior Perception Hardware Engineer focusing on Sensor Calibration, you will own the critical link between the physical world and our robot's autonomy stack.
- You will design the physical fixtures, write the calibration algorithms, and build the scalable factory processes that define the intrinsic, extrinsic, and temporal calibration of our humanoid robots.
- Define and implement robust intrinsic models for various optical sensors (e.g., pinhole, fisheye, Brown-Conrady, Kannala-Brandt) and inertial sensors (bias, scale factors, random walk).
- Develop highly accurate sensor-to-sensor and sensor to kinematic base spatial transformations.
- Sensor Modeling: Define and implement robust intrinsic models for various optical sensors (e.g., pinhole, fisheye, Brown-Conrady, Kannala-Brandt) and inertial sensors (bias, scale factors, random walk).
- Extrinsic Calibration: Develop highly accurate sensor-to-sensor and sensor to kinematic base spatial transformations.
- Hardware & Fixture Design
- Mounting & Stability Validation: Collaborate with mechanical engineers to evaluate and optimize sensor mounting rigidity. Characterize calibration drift caused by thermal gradients, mechanical shock, and joint wear.
- End-of-Line (EOL) Automation: Build the automated calibration pipeline for our manufacturing line, allowing non-engineers to reliably calibrate a multi-sensor humanoid head in minutes.
- Online/In-Field Calibration: Develop lightweight "auto-calibration" or self-diagnostic routines that allow Apollo to detect sensor drift in the field and dynamically adjust its extrinsic transforms without human intervention.
Requirements
- Ability to translate abstract autonomy requirements (e.g., "we need 1cm grasping accuracy at 1 meter") into concrete hardware and calibration tolerances.
- Must be able to lift 15 pounds at times
- Software Proficiency:
Benefits
- Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond.
