Reducing Pick-and-Place Cycle Time: Approaches and Trade-offs
Pick-and-place cycle time is determined by motion time plus settling time plus process time (gripper actuation, vision confirmation). Settling time is often the largest controllable variable.
Unlocking Hidden Capacity in Existing Pick-and-Place Automation
Manufacturers invest in pick-and-place automation expecting a specific throughput. In practice, vibration at each stop point can force pauses that strand capacity in existing equipment.
Why Your Pick-and-Place Robot Isn't as Fast as It Should Be
The robot's spec sheet says it can move fast enough. The trajectory looks efficient. But actual throughput is lower than the math suggests because vibration forces a wait at every pick and place.
Settling Time as the Binding Constraint in High-Speed Pick and Place
In pick-and-place applications, cycle time is often assumed to be limited by the robot's maximum joint velocity or acceleration. In practice, the binding constraint is frequently settling time.
Dynamic Vibration Compensation for Industrial and Collaborative Robot Arms
Learn how residual TCP vibration increases robot settling time, and how model-based feedforward compensation can reduce vibration without replacing the robot.
The Hidden Cycle-Time Cost of Robot Vibration
Your robot reaches a precision stop — a pick point, a weld start, a dispense location — and the tool vibrates before it settles. You see it in inconsistent bead width at corners, scrap from…
