Design Human Avoidance for Warehouse Robots

Company: Amazon

Role: Software Engineer

Category: System Design

Difficulty: medium

Interview Round: Technical Screen

Design a software module that allows an autonomous warehouse robot to avoid humans while navigating. Your answer should cover: - Which sensors you would use and why. - How sensor data flows through the system. - What data structures you would use to represent nearby humans, obstacles, and the robot's planned path. - How the robot decides whether to continue, slow down, stop, or re-plan. - Pseudocode for the core collision-avoidance loop. - A high-level architecture showing the main components and their responsibilities. Assume the robot operates indoors in a warehouse, moves among shelves and people, and must prioritize human safety over speed.

Quick Answer: This question evaluates competencies in robotics perception, sensor fusion, motion planning, obstacle and human representation, real-time decision-making, and safety-critical system architecture within the system design domain.
