The Hidden Cycle-Time Cost of Robot Vibration

The symptom

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 misplaced parts, or a cycle time that should be faster but isn't.

Slowing the robot down helps, but costs throughput. Adding dwell time at each stop works, but the line is waiting instead of producing.

What's happening

Every robot arm flexes during motion. When the process requires the robot to stop accurately, the line has to allow enough time for that residual vibration to settle before the next operation begins. That wait adds up — across hundreds or thousands of precision stops per day, it can represent a meaningful share of your cycle time.

How Shaper addresses this

Reforge's Shaper is software that reduces the excitation of robot vibration. It learns how your specific robot arm vibrates, then modifies the motion commands so the arm arrives at position with less overshoot and less oscillation.

Shaper works through the robot's existing command interface without modifying its mechanical system or replacing its controller. No permanent sensors or mechanical modifications. Deployment can be scheduled around planned production downtime.

An initial calibration is performed for each robot. If payload, tooling, or mounting changes significantly, the model can be revalidated and fine-tuned.

Results

In testing, Shaper has demonstrated:

• More than 80% reduction in vibration

• Up to 2x throughput improvement by eliminating settling time overhead

• Shorter cycle times using existing equipment, without buying a faster robot or adding a second arm

Example

In an application where Shaper reduces total endpoint dwell by two seconds per cycle — across 1,000 daily cycles and 260 operating days — it can free approximately 144 robot-hours of annual production capacity per arm.
