Troubleshoot communication failures and implement appropriate retry/error-handling mechanisms.

1. Robotics & Motor Control

Work with motor controllers, motors, encoders, and related hardware. Support robot movement and control-related firmware.

Understand basic concepts of motor control, feedback, sensors, and safety mechanisms.

1. HardwareSoftware Integration

Interface embedded firmware with sensors, motor drivers, battery-monitoring systems, and other electronic components. Perform hardware bring-up and board-level testing.

Use datasheets and hardware schematics to understand interfaces and troubleshoot issues.

1. Debugging & Testing

Debug firmware and identify root causes of hardware/software issues. Perform unit, integration, functional, and system-level testing.

Analyze logs, CAN messages, serial output, and other diagnostic information.

Reproduce, document, and resolve field/test failures.

1. System Monitoring & Diagnostics

Implement system health monitoring and fault detection. Develop diagnostic logs and error-handling mechanisms.

Support development of mechanisms for detecting communication, sensor, battery, and motor-related failures.

1. Documentation

Create and maintain technical documentation for firmware, interfaces, test procedures, and troubleshooting. Document bugs, root causes, corrective actions, and test results.

Maintain transparent code comments and development records.

1. Collaboration

Work closely with hardware, firmware,



mechanical, testing, and system engineering teams. Participate in design discussions, code reviews, testing, and technical problem-solving.

Support engineers during robot integration and validation.
