Sizing tool
Find a robot by payload and reach
Payload is how much the arm can carry. Reach is how far it can stretch. Set both floors on the chart, drag the amber handles, and the Match count updates live against all 91 published robot profiles in the catalog, ranked by the tightest fit.

Specs come from each model’s verified datasheet fields. This is a sizing shortlist, not a cell design: end-effector mass, inertia, mounting, and duty cycle still decide whether an arm actually fits the job. Open a model page for the full sheet, browse the full catalog, or compare two arms.
How this shortlist works
This tool builds a sizing shortlist by comparing your minimum payload and reach floors against verified datasheet specs from our published robot catalog. It ranks arms that clear both floors by how little they oversize the job, then flags close calls that just miss one axis.
How matching works
You set a minimum payload in kilograms and a minimum reach in millimeters. Those two values are hard floors, so a robot only counts as a match when its rated payload meets or exceeds your payload floor and its reach meets or exceeds your reach floor. The chart amber handles let you drag both thresholds, and the Match count updates live as you move them.
Optional brand and robot class filters run before the floor check, so anything outside those filters drops from the pool first. Every spec in the comparison comes from the same verified datasheet fields shown on each robot model page. Nothing here is estimated on your behalf.
How ranking works
Matches are ranked by least oversizing, which we track as a waste score. The score is (payload minus needed payload) divided by needed payload, plus (reach minus needed reach) divided by needed reach, so a lower score means a tighter fit that still clears both floors. Ties break alphabetically by model name, and each match also shows its payload and reach headroom above your requirement.
Near-misses
A near-miss is a robot that meets one floor but falls short on the other by no more than 20 percent of that requirement. The axis that is not short must still clear its floor, so a near-miss is never short on both payload and reach at once. We surface these because a small floor adjustment or a lighter end effector sometimes brings a strong candidate into range, and near-misses are sorted by the smallest shortfall first.
What this tool does not do
This is a sizing shortlist, not a cell design or payload curve calculator. It does not model tool center point offset, wrist inertia, duty cycle, or how rated payload drops as the arm extends. Treat the results as a starting list to verify against full datasheets and your own application load case.
Worked examples
Here are three common ways technicians use the floors to shape a shortlist.
1. Light machine tending
For a small machine tending cell handling light parts and a compact gripper, set payload near 5 kg and reach near 900 mm. The shortlist returns arms that clear both floors, ranked so the tightest fit sits on top instead of an oversized arm you do not need.
2. Mid payload packing and reach
For case packing or light palletizing, raise the payload floor to about 20 kg and push reach past 1600 mm to cover the pallet footprint. The waste score keeps arms with huge extra reach lower in the list, so you can weigh headroom against cost.
3. Near-miss on one axis
Say you need 10 kg and 1400 mm, and an arm is rated 10 kg but only 1300 mm. It misses reach by 100 mm, which is about 7 percent, so it appears as a near-miss rather than a match. Trimming your reach floor or shortening the tool may pull it into the hard matches.
Next steps
Open any model link to review the full datasheet in the robot catalog and confirm the specs against your load case. When two candidates line up, use the compare link to see them side by side before you shortlist. Start from the defaults of 10 kg payload and 1000 mm reach, then adjust the floors to your real requirement.
