High Speed Closed-Loop Control for Sawyer Motors
Development of Autopilot Hardware for Autonomous Helicopter
Hardware-In-The-Loop Helicopter Simulator
MEMS Based Inertial Measurement Unit (IMU)

Senior Year Project : MC68HC11 Based Programmable Micromouse
A Micromouse is a small robot which is normally built for competitions in maze solving, duel, etc. This Micromouse was designed and developed to be programmable to suit various applications through a RS232 communication link. Designed a microcontroller board, a sensor interface board and a stepper motor control board for the Micromouse. A Visual C++ program was written to interface to the serial port of the microcontroller board to transfer applications.
