Robotics Engineer

VDA Remote | Relay Product | TTP
≥ Focused on resolving customer-reported issues, ensuring stable deployments, and supporting ongoing operations across customer sites such as Apotek, O&M, Walmart, Luxottica, H&M, Sam’s ATL, FHR, and Sedico. Activities included debugging VDA Remote behaviour, resolving robot collisions, tote handling issues, and stabilizing task execution flows to ensure smooth warehouse automation operations.
≥ Provided fixes as per root cause analysis of critical VDA Remote defects including incorrect task completion, pause loops, and running-state deadlocks, providing both immediate hotfixes and long-term solutions.
≥ Debugged and resolved tote-handling issues such as unassignment, data mismatches, and unload inconsistencies, while supporting robot-collision and operational-failure investigations.
≥ Applied a data-driven debugging approach using logs and system behavior analysis, effectively communicating findings during cross-team RCA discussions.
≥ Delivered features and fixes for Relay deployments (Apotek, O&M, Walmart) within committed timelines and quality targets.
≥ Contributed to product stability through feature development, debugging, testing, integration, and production support.
≥ Supported release activities and ensured smooth deployment of enhancements and bug fixes.
≥ Developed error-handling workflows for charging, ODS, and retrace scenarios to improve operational robustness.
≥ Implemented CIP-based safety pause functionality and ODS zone support for enhanced safety compliance.
≥ Added support for new bot variants and contributed to VTM/HTM workflow enhancements.
≥ Performed broader codebase improvements, integrations, and system-level optimizations.

PPTL (Electronics Hardware / Firmware)
≥ Stepped in to support the Peripherals team in the absence of dedicated resources and delivered PPTL firmware releases.
≥ Modified firmware to support 2¹⁶+ field IDs while maintaining backward compatibility with existing deployments.
≥ Upgraded the bootloader to support new firmware versions without impacting legacy devices.
≥ Enhanced the programmer tool (C & Python) to support both old and new firmware, reducing maintenance overhead.
≥ Developed and executed test cases to validate firmware functionality and reliability.

IMB (Integrated Motherboard)
≥ Worked on Integrated Motherboard (IMB) systems, handling both hardware and Linux-based software integration in an industrial environment.
≥ Set up and manage Linux automation workflows using Supervisor, crontab, and system-level process control.
≥ Built a strong understanding of industrial Linux filesystem architecture, application structure, configuration management, and supporting services.
≥ Troubleshoot hardware issues through schematic analysis and collaborating on implementing effective solutions.

RTP (Orin Nano & IMB Bring-Up)
≥ Supported RTP hardware bring-up activities for NVIDIA Orin Nano and IMB platforms.
≥ Re-stabilished and debugged camera, ODS, and Non-RT issues during platform integration.
≥ Performed benchmarking, system validation, and integration testing to ensure platform readiness.
≥ Assisted in resolving hardware and software interoperability challenges across the RTP stack.

Diagnostics & Automation Tools
≥ Developed phased LiDAR error reporting mechanisms to improve diagnostics and troubleshooting.
≥ Created LiDAR alignment automation scripts (GFC-2) for faster deployment and calibration.
≥ Built Ethernet debugging utilities and CPU/NVMe performance monitoring tools.
≥ Improved observability through enhanced logging, navigation-log analysis, and user-friendly firmware flashing solutions.

Validation & Release Support
≥ Conducted trial runs, sanity testing, and verification activities to ensure release stability.
≥ Supported production deployments and post-release monitoring for VDA Remote and Relay products.
≥ Collaborated with cross-functional teams to validate fixes, features, and system behavior before release.

Embedded Engineer

IPU Algorithm Enhancement
≥ Released a stable Image Processing Unit (IPU) version, improving accuracy from 55% to 93%.
≥ Developed a Python-based data matrix decoding algorithm, reducing "DM not found" issues.
≥ Increased decoding capabilities by 40% and accuracy by 30%.
≥ Solved challenges like uneven lighting and LED inconsistencies.

Lidar Enhanced Vision Development
≥ Improved bot navigation by enabling Lidar to ignore specific objects and slow down for safety.
≥ Ensured non-human obstacles (e.g., rack legs) were ignored while detecting real obstacles.
≥ Enhanced bot safety and performance in complex environments.

Lidar Diagnostics
≥ Developed and tested a module for detecting and reporting diagnostic issues.
≥ Designed test cases to verify shell placement for Lidar stability.

Lidar Internal Warnings & Error Reporting
≥ Integrated a standalone C++ open-source project into a ROS-based system for error reporting.
≥ Extended functionality to work with the navigation interface (non_rt_interface).
≥ Created JSON-based feasibility analysis for development.
≥ Designed and tested cases to log and verify internal Lidar warnings and errors.

Lidar OTA
≥ Implemented Over-the-Air (OTA) firmware updates for Lidar, enabling remote updates via Windows → Server → TX2 → Lidar.
≥ Focused on networking aspects of the update process.
≥ Successfully executed and validated OTA updates.
