#### 2.4A robotics instructor is programming a robot to move in a precise path that consists of 120 equally spaced waypoints. The robot starts at the first waypoint and moves to the last, covering the distance between each consecutive pair in 1.5 seconds. How many seconds does it take the robot to complete the entire path, including the final stop at the last waypoint? - Parker Core Knowledge

How Long Does It Take a Robot to Follow a Path of 120 Waypoints? A Clear Breakdown
In today’s automation-driven world, precise robotic motion is reshaping industries from manufacturing to delivery and beyond. Users often ask: how long does it take a robot-like system to traverse a sequence of 120 equally spaced waypoints when moving smoothly between each, spending 1.5 seconds per step and stopping at the final point? This question reflects growing interest in how real robots execute planned trajectories efficiently. Behind the short answer lies a straightforward calculation rooted in timing logic—ideal for those curious about robotics programming and motion timing in automated systems.
This detailed breakdown reveals how robot paths are timed using consistent intervals, offering clarity to curious learners, educators, and professionals navigating automation technology.
Understanding the Context
The Mechanics of Precise Motion: Breaking Down the Timing
When a robot follows a path of 120 equally spaced waypoints, movement occurs in 119 intervals—since it starts at the first waypoint and ends after completing motion to the 120th. Each interval between adjacent waypoints takes 1.5 seconds, so the total travel time spans from start to final stop. Multiplying the number of intervals by duration per interval gives:
119 intervals × 1.5 seconds = 178.5 seconds

Key Insights
Adding the final second of full completion at the endpoint, the full cycle takes 178.5 seconds to complete—ensuring accuracy even at the endpoint.
Why Precise Timing Matters in Robotics
Accurate timing isn’t just a technical detail—it defines responsiveness and reliability in automation. In real-world applications, robots following coordinated paths must align with sensors, safety checks, and scheduling systems. Using a consistent interval like 1.5 seconds per waypoint prevents timing drift, ensuring synchronized operation across multiple units. This predictability supports efficient workflow, reduces cycle delays, and builds trust in robotic task execution.
