problem
- ›Building a small autonomous platform that could track and follow a person in real time.
- ›Ultrasonic sensing alone gives no directional feedback — the chassis had to decide where to steer.
architecture
- ›Arduino Uno as the controller.
- ›Multiple ultrasonic sensors arranged to give left/center/right distance readings.
- ›Motor driver + differential drive chassis for steering decisions.
technologies
- ›Arduino Uno
- ›Ultrasonic sensors
- ›Motor driver
- ›C++ (Arduino)
security
- ›Not applicable — prototype hardware with no network exposure.
what i built
- +Sensor array mounting and wiring.
- +Decision logic for follow, stop and re-acquire.
- +Chassis calibration for straight-line tracking.
what i learned
- +Sensor noise dominates — averaging readings beats trusting a single ping.
- +Simple reactive logic goes a long way without any AI.
- +Prototype assembly time is mostly cable management.
current status
Complete as a prototype and demonstrated at UniKL. Retired to the shelf while I focus on network-focused projects.
