Aathi Jeyakumar

Hardware security and embedded systems engineer with experience in fault injection, custom tooling (Python/C++), PLC design, and microcontroller-based control systems for fault injection, and secure system analysis.

Inverted Pendulum

• Designed and built a self-balancing inverted pendulum system using a PID control loop
• Programmed control algorithms on an Arduino microcontroller to maintain upright stability and correct for disturbances. This system controls the body position along the rail, which changes its orientation.
• Brought together motor drivers, sensors, and actuators into a working control feedback loop.

Automatic Plant Watering System

• Built an automatic plant watering system using an Arduino Uno, integrating temperature, humidity, and soil moisture sensors to monitor real-time environmental conditions.
• Programmed sensor-based decision-making logic using if statements and loops to activate a water pump through a 5V relay.
• Simulated sensor behavior and control logic in Simulink to visualize system performance and validate decision-making before hardware implementation.

Four Leg Tripod 

• Designed a four-legged robot that can navigate human environments by relying primarily on mechanical components

• The robot consists of motor subassemblies, leg subassemblies, gait control subassembly, the direction change subassembly, and the balance control subassembly

Gyroscopic Simulation and Torque Analysis

• Used MATLAB to simulate how a gyroscope responds to changing forces, tracking its position, speed, torque, and power over time.
• Modeled the system using rotational dynamics and linked local and global axes to capture realistic gyroscopic motion.
• Showed that the gyroscope could successfully resist external disturbances throughout a full rotation cycle (0 to 2π seconds).
