We make UAS systems that you can trust, WE dont do this to live rather we live for it

Selected Work

GSoC 2024

Visual Follow Me For Copters

Wrote the tracking pipeline that lets an ArduPilot copter lock onto a person or vehicle in a camera feed and follow it autonomously. Algorithms onboard, MAVLink close the loop to the flight controller no cloud dependency.

Camera & Gimbal Enhancements

Added time-interval photo triggering, point-at-circle-center mode, and vehicle-follow tracking to ArduPilot's camera/gimbal subsystem. All merged upstream this code now runs on every ArduPilot copter that uses a gimbal.

Autonomous VTOL Landing on Moving Platform

Built the full autonomy stack for a hybrid VTOL detect a moving ground platform via vision, estimate its velocity, compute the intercept trajectory, and land with centimetre-level precision. Integrated battery-swap mechanism for continuous ops.

Field Robots Rovers & Quads

End-to-end agriculture autonomy: Rovers, Tracktors and Quads. Make farmers more productive.

Swarming

Multi-Drone Swarm Coordination

Built both mesh-network (decentralised) and server-client (centralised) swarm architectures on ArduPilot/PX4. Each drone is smart, with built-in collision avoidance, formation flying, and dynamic task reassignment all running in real time.

What We Build

01

Autonomous UAVs

Full-stack drone development flight controller firmware, companion computer setup, sensor integration, and mission logic. We've shipped copters, planes, and VTOLs from prototype to production.

02

Intelligent Robotics

Ground vehicles that navigate without GPS, pick objects with vision-guided arms, and coordinate with aerial assets. ROS2 on Jetson, sensor fusion, and real-time path replanning.

03

Computer Vision Pipelines

Object detection and tracking that runs on edge hardware. custom models for domain-specific targets boats, vehicles, people, crop health.

04

Simulation & Digital Twins

SITL and HITL testing before anything flies. Gazebo, CARLA, AirSim realistic sensor models, physics, and terrain. We catch bugs in simulation so you don't catch them in the field.

05

Navigation & State Estimation

EKF-based sensor fusion GPS, IMU, magnetometer, barometer, optical flow, visual odometry. GPS-denied navigation. The math that turns noisy sensor data into a position you can trust.

06

Embedded Firmware

Bare-metal C on STM32, RTOS on flight controllers, Linux on companion computers. Code that runs in 400Hz control loops with deterministic timing no garbage collection, no surprises.
