Autonomous control
and robot iteration.
I competed in VEX Robotics for three years and mentored underclassmen for one year. The 2021–22 notebook identifies me as the main programmer; the 2023 team biography records my later role as captain.
My contributions
- Co-developed tracking-wheel and gyro-based odometry with a teammate, including a rotation routine to estimate tracking-wheel offsets.
- Developed modular C++ autonomous motion routines with four modes: acceleration to constant speed, constant speed, deceleration, and combined acceleration/deceleration.
- Proposed a pneumatic ring-handling mechanism and collaborated on prototype iteration and robot integration.
Design iteration
The initial ring-container concept used passive pickup and a pneumatic release. Testing exposed friction that made pickup and reset difficult. The team refined the mechanism with a one-way trapdoor and integrated it near the robot's front clamp.
The control routines were used to combine movement segments during autonomous operation. The notebook records qualitative observations; it does not establish a measured localization error or a quantified performance improvement.
A teammate and I developed the tracking algorithm. Teammates identified friction and release issues during prototype testing and proposed the trapdoor refinement. These were collaborative engineering decisions.
