Charles Shaju

Robotics and embedded engineer with 2+ years in marine robotics (ASVs, underwater ROVs), now pursuing an MCA to move into perception and autonomy. Tuned PID control on an 80 kg catamaran ASV used for dam surveys at 4 sites; building a ROS2 mobile robot with EKF sensor fusion on Raspberry Pi and ESP32.

Embedded Systems Engineer at i4 Marine Technologies Pvt Ltd (2023-08 – Present)

Present (part-time since June 2025)

• Tuned steering, speed and acceleration gains on an ArduPilot/Pixhawk catamaran ASV (80 kg payload), using Mission Planner gyro graphs and logs to remove path zigzag; held planned survey lines within 1 m during bathymetry and dam-wall inspection at 4 dams.
• Set up UDP telemetry over radio modems and a live sensor-data UI for the ASV up to 2-3km
• Wired, configured, calibrated and tested underwater ROVs, including a commercial BlueROV.
• Built IoT speed-control modules for electric canoes; currently building GPS IoT modules for [spell out OBM] and a precision barometer.

EdTech & Robotics Solutions Engineer (Intern) at Jobin & Jismi (2026-04 – 2026-05)

Internship

• Built a browser-based block-programming platform (Google Blockly + JavaScript) that connects over Bluetooth to an ESP32 Otto robot, so students can drive it and program it with blocks.
• Tested and debugged the Edu robot’s motor control and movements.

Robotics Intern at Shristi Robotics (2023-01 – 2023-07)

• Built a 6-thruster underwater ROV (Pixhawk, ArduSub) on a funded project: wiring, calibration and testing; deployed for inspection
• Operated a 3D printer to produce ROV components.
• Taught mobile robotics, sensors and Arduino: a 2-week summer course for school students and one-day workshops for college students.
