01 — Overview
Designed and built a fully autonomous robot capable of navigating complex environments including line-following, wall-following, and 4-way junction obstacle avoidance with mobile app control.
02 — Problem Statement
Autonomous navigation in unstructured environments requires robust sensor fusion and decision-making algorithms that can handle edge cases like dead zones and multi-path junctions.
03 — Objectives
- 01Implement reliable line following using IR sensors
- 02Add wall following mode using ultrasonic sensors
- 03Handle 4-way junction decisions with obstacle avoidance
- 04Provide mobile app manual override and dead-zone recovery
04 — Key Outcomes
Multi-mode navigation: line following, wall following, obstacle avoidance
Intelligent 4-way junction handling with priority logic
Mobile app control with real-time mode switching
Dead-zone recovery algorithm for stuck-state resolution
