Research

RESEARCH & ENGINEERING

Research shaped by real systems. Building and testing robots has raised practical questions around perception, heat, communication, localization, and control. Current direction: reliable autonomous robots that keep working when conditions become difficult. Open to graduate research, R&D opportunities, and selected robotics projects.

01

Onboard Perception in Real Conditions

YOLOv8 Nano initially ran at 25 ms per frame (~15 FPS) on a Raspberry Pi 5. During sustained operation in 34°C ambient heat, inference increased to 32 ms as the processor reached 76°C. A five-frame verification method rejected 88% of temporary false detections during field tests.

02

Autonomy with Unreliable Communication

The UAV maintained stable video and MAVLink telemetry to 180 m over a 5 GHz link. Beyond 200 m, packet loss caused video delays of up to 3 seconds, while onboard detection continued to run. This made local decision-making an important part of the system design.

03

Localization, Mapping & Navigation

Research work at NCAI included ROS 2 Jazzy, Gazebo, URDF/XACRO, Cartographer SLAM, and Azure Kinect integration with Jetson Nano. In later UAV field tests, GPS-guided navigation reached a measured lateral tolerance of ±1.5 m.

04

Embedded Flight & Control

A custom ESP32 + MPU6050 flight controller achieved stable hover and attitude control, with PID gains adjustable live through a browser interface. Other embedded work includes local vision-based motor control on ESP32-CAM and bare-metal firmware development on the 8051.

Process

How I build systems

Every build starts with the limit most likely to shape the system, weight, power, sensing, control, compute, or range. I test that early, integrate the subsystems around it, then validate the complete system with real measurements.

Stable telemetry range

UAV testing covered communication range, waypoint accuracy, inference speed under heat, and flight time. The video and MAVLink link stayed stable up to 180 m, which made it easier to see where the system was reliable and where it still needed work.
