Cycle time for a pick-and-place task is typically computed by summing which components?

• A. Pick, Transit, Release, and Dwell
• B. Pick, Transit, Release
• C. Pick, Transit, Release, Dwell, and Acceleration/Deceleration Phases, including Sensor Waits and Path Planning Delays
• D. Transit and Dwell only

Answer: (C)

Cycle time is the total time to complete one pick-and-place cycle, from the moment the cycle starts until it’s ready to begin the next one. To capture the true duration, you must include every phase that adds latency: the time to pick the part, the transit time as the arm moves to the destination, the release time, and any dwell time required for stabilization or verification. Don’t forget the time spent accelerating to speed and decelerating to stop, which can be substantial in fast systems. Also include delays from sensors (vision or measurement waits) and path planning (computing safe trajectories or re-planning in dynamic conditions). Because all these parts accumulate, the cycle time is the sum of Pick, Transit, Release, Dwell, and the Acceleration/Deceleration Phases, along with Sensor Waits and Path Planning Delays. Other options omit one or more of these elements, which would underreport the true cycle time.
