Collaborated with a team of 4 to design an autonomous delivery robot with a 2‑point hitch trailer for use in hospitals. The system navigates pre‑mapped indoor paths, avoids obstacles, and maintains localization despite wheel slip.

Implemented a weighted undirected graph in C++ with Dijkstra's algorithm for shortest‑path navigation, prototyped encoder‑based localization, designed a caster‑wheeled trailer in Onshape, and built a wireless prototype interface using Arduino WiFiNINA and a web UI.

• Achieved functional navigation and localization subsystems and a working wireless prototype interface.

Designed, built, and programmed a functional model elevator that leverages data structures to efficiently manage user requests for pick-ups and drop-offs.

Implemented two doubly linked lists to track active elevator requests and a separate node for priority users, optimizing efficiency in request handling. Designed the model elevator using Onshape. Developed the hardware system including a 1-inch LCD display, a motor driver to control elevator movement, and a magnetic encoder to accurately track the elevator's position.

• All implemented data structures and algorithms functioned as expected for Call, Delete Call, and Priority Requests.
• Mechanical components performed reliably: functional floor buttons, priority button, and smooth door operation.

Programmed a MiniBot to follow a black line and pick up blocks using an IR sensor. The goal was to have the MiniBot follow the line in a circle and pick up blocks three times with a minimum of 5 per time.

Calibrated sensor voltage readings for line detection and coded Arduino control to adjust wheel speeds to stay on the line. Used an optimized block layout to maximize pickups per run.

One of two groups to pick up all 50 blocks, creating a tie for first.
