Robot Pick Rate Calculator

Robot pick rate is the sustained throughput a pick-and-place, palletizing, or case-packing cell can actually hold over a shift, expressed in picks per hour. It is the number automation engineers and line managers quote when sizing a delta robot, SCARA, or 6-axis handling cell against a demand rate. Raw throughput looks great on a data sheet, but once you derate it for downtime, jams, vision misses, and micro-stops, the sustained rate is what feeds a realistic capacity plan. This calculator separates the two so you can commit to a number you will still hit at 3 p.m. on a Friday.

What this calculator does

  • Estimate sustained robot pick rate in picks per hour from logged picks, runtime, and a realistic cell efficiency.
  • Use it for delta, SCARA, or 6-axis pickers on conveyor, blister, or kitting lines when you need a pick rate you can defend to operations.
  • It computes sustained robot pick rate by dividing picks completed by measured runtime and then multiplying by expected cell efficiency.

Formula used

  • Pick throughput = picks completed / cell runtime
  • Sustained robot pick rate = pick throughput x expected cell efficiency

Inputs explained

  • Picks completed in the window:
  • Cell runtime measured:
  • Expected cell efficiency (uptime x quality):

How to use the result

  • Use it when validating a vendor's cycle-time claim, sizing a cell to a takt requirement, or converting an observed pick count into a plannable hourly rate.
  • Efficiency here is a single blended factor; if a real cell loses time to distinct causes (starvation, blocking, vision retries) you should measure each rather than trusting one guessed percentage.

Current U.S. benchmarks

  • Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.

Common questions

  • How do you calculate robot pick rate? Divide picks completed by cell runtime to get raw throughput, then multiply by expected cell efficiency. With 28,800 picks over 8 hours at 85% efficiency, raw throughput is 3,600 picks/hr and the sustained rate is 3,060 picks/hr.
  • What is a good pick rate for a delta robot? Fast delta robots on light, well-presented parts can hit 150-200 picks/min per arm (9,000-12,000/hr) in bursts, but sustained cell rates after vision and infeed losses are usually a fraction of that. Judge your number against takt, not the data sheet peak.
  • Why is my sustained rate lower than the raw throughput? Raw throughput assumes zero lost time. Sustained rate applies your efficiency factor for micro-stops, jams, changeovers, and vision retries. The 540 picks/hr gap in the example (3,600 vs 3,060) is exactly that 15% loss.
  • Pick rate vs cycle time - what's the difference? Cycle time is seconds per pick for one motion; pick rate is picks per hour across the whole cell including losses. A 1.0-second cycle implies 3,600 picks/hr in theory, but the sustained pick rate tells you what the line delivers.
  • What efficiency should I assume for a new cell? For a mature, well-fed cell, 85-92% is realistic. New installs and cells with vision-dependent picking often run 70-80% until infeed presentation and grip reliability are tuned. Use conservative numbers for capacity commitments.
